Basic concepts of survival

Human life has always been fraught with danger. It is no coincidence that our distant ancestors, taking their first steps along the path of evolution, learned to use the stone not only as a tool of labor, but also as a weapon.

The struggle for existence forced people by hook or by crook to cling to life, to adapt to any adversity, no matter how difficult they may be, to boldly go towards dangers. The desire to achieve the seemingly impossible, permeating the entire history of mankind, helps to understand the incredible efforts made by people in various parts of the world in order to adapt to the harsh natural conditions. Man has always had the ability to adapt to the natural and artificial environment - from primitive hunters who went out to the beast with a stone ax in their hands, to space travelers of the second half of our century, who have been in a state of weightlessness for a long time, mobilizing all their physical and mental capabilities. Survival is active, expedient actions aimed at preserving life, health and performance in an autonomous existence. It is for people whose lives are constantly fraught with dangers that preliminary preparation, both physical and psychological, is very important. Rescuers, military personnel of many branches of the military, tourists who go on long routes, many scientists and researchers must first go through a complete adaptation process, as a result of which the body gradually acquires resistance to certain factors that was previously absent environment and thus gets the opportunity to "live in conditions previously incompatible with life", which means complete adaptation to the conditions of polar cold, hot deserts or lack of oxygen at mountain heights, fresh water in the salty sea. People who have undergone full adaptation have a chance not only to save life itself, but also to solve problems that were previously unsolvable.

The adaptation process is very complex and multi-stage. At its first stage, the stage of adaptation to any new factor, the body is close to the maximum of its capabilities, but it does not solve the problem that has arisen completely. However, after some time, if a person (or animal) does not die, and the factor requiring adaptation continues to act, the possibilities of the living system increase - the extreme, or urgent, stage of the process is replaced by the stage of effective and stable adaptation. This transformation is the key link in the whole process, and its consequences are often striking. Extreme conditions - an event (or a sequence of events) in which a person, through his own preparedness, the use of equipment and gear, as well as the involvement of additional, pre-prepared resources, has the opportunity to prevent an emergency, and, if necessary, help himself and others after an emergency. An extreme situation is an event outside of personal human experience, when a person is forced to act (or remain inactive) in the complete absence of equipment, equipment and initial training. (Basic information about ways to overcome the ES is not formalizable in principle, based on the very definition of an extreme situation). Most people and animals placed in extreme situations from which there is no way out do not die, but acquire one or another degree of adaptation to them and save their lives until better times. Such stressful situations - long periods of hunger, cold, natural disasters, interspecific and intraspecific conflicts - are always widely represented in the natural habitat of animals. The same scheme operates in the human social environment. During a relatively short period of its history, humanity went through periods of slavery, serfdom, world wars, but did not degrade, demonstrating high efficiency of adaptation to extreme situations. Of course, the price of such adaptation is unreasonably high, but these indisputable facts inevitably lead to the conclusion that the body must have sufficiently effective specialized mechanisms that limit the stress response and prevent stress damage and, most importantly, allow one to save life and health. In general, all this corresponds to a well-known everyday observation - people who have gone through severe life tests acquire a certain resistance to damaging environmental factors, i.e. resilient in any extreme situation. Imagine that a miracle happened, and today's man suddenly found himself in the primitive conditions of the existence of mankind. Making his way along the damp walls of the cave, to the sonorous chatter of his own teeth, our hero recalls the fire with unexpected joy. What about chopping wood? Well, okay, you can break the branches. He habitually hits himself in the pocket. Oh, horror, no matches! At first, our time traveler does not realize the full depth of the catastrophe that has befallen him. But in a minute it is covered with cold sweat. He has no idea how to make a fire without matches! Feverish attempts to make fire by rubbing wooden sticks against each other, cutting sparks lead to nothing - kindling stubbornly does not want to flare up. Further, with inexorable consistency, it turns out that a representative of our time cannot hunt without a gun, fish without lines and hooks, cannot build even the most primitive shelter, has no idea how to protect his mortal body from hundreds of dangers lurking from all sides. Hunted looking around, he rushes through the ancient forest, occasionally attacking the berries, which do not saturate at all. Our contemporary is doomed. He has to survive in conditions of autonomous existence. Autonomous existence is the activity of a person (a group of people) without outside help. The only chance to prolong their existence is to seek help from the local natives. It's nothing you can do! And then he meets the real masters of that era: the genius of getting food, the genius of making fire. With great effort, starting from the very basics, the unlucky traveler comprehends the science of "survival", with difficulty pulling himself up to the level of development of primitive man. There is nothing exaggerated in this fantasy. Even astronauts, before taking their place in spaceship, walk hundreds of kilometers along the paths of survival - forest wilds, hot sands of deserts. Modern man, and even more so, a professional rescuer, regardless of the planned actions and the route of movement in terrestrial and extraterrestrial space, timing and geographical location, must be ready to act in an emergency, without communication with the outside world, when you can rely only on yourself. For a person who finds himself in an extreme situation due to unforeseen circumstances, such as a plane crash, a shipwreck, military personnel, as well as lost tourists, survival is mainly a psychological issue, and the most important factor in this case is the desire to survive. Regardless of whether a person is left alone or as part of a group, emotional factors may appear in him - experiences due to fear, despair, loneliness and boredom. In addition to these mental factors, trauma, pain, fatigue, hunger, and thirst also influence the will to survive. How long will a person in trouble have to stay in conditions of autonomous existence in extreme conditions? It depends on a number of reasons that determine the duration of autonomous existence.

The reasons for the duration of autonomous existence:

Remoteness of the area of ​​search and rescue operations from settlements;

Violation or complete absence of radio communications and other types of communications;

Unfavorable geographical, climatic and meteorological conditions of the area of ​​search and rescue operations;

Availability of food stocks (or lack thereof);

The presence in the area of ​​search and rescue operations of additional search and rescue forces and means.

Goals and tasks of rescuers on survival issues

The purpose of training rescuers for survival is to develop in them stable skills for actions in various conditions of the situation, to develop high moral and business qualities, self-confidence, reliability of rescue equipment and equipment, and the effectiveness of search and rescue support.

The basis of survival is solid knowledge in various fields, from astronomy and medicine to the recipe for cooking dishes from caterpillars and tree bark.

Survival techniques in each climatic and geographical region are different. What can and should be done in the taiga is unacceptable in the desert and vice versa.

A person must know how to navigate without a compass, give a distress signal, go to a settlement, get food with the help of gathering, hunting, fishing (including without a gun and the necessary gear), provide himself with water, be able to protect himself from natural disasters and much more. other.

The practical development of survival skills is extremely important. It is necessary not only to know how to behave in a given situation, but also to be able to do it. When the situation becomes threatening, it is too late to start learning. Before high-risk trips, it is necessary to conduct several emergency field exercises that are as close as possible to the real situation of future routes. It is necessary to calculate in advance theoretically and, if possible, check almost all possible emergencies.

The main tasks of training rescuers for survival are to provide the necessary amount of theoretical knowledge and teach practical skills for:

Orientation on the ground in various physical and geographical conditions;

Providing self- and mutual assistance;

The construction of temporary shelters and the use of improvised means of protection from the effects of adverse environmental factors;

Obtaining food and water;

Use of means of communication and signaling for the withdrawal of additional forces and means to the area of ​​search and rescue operations;

Organization of crossings through water barriers and swamps;

Use of rescue boats;

Preparation of sites for landing helicopters;

Evacuation of victims from the disaster area.

Factors affecting survival

Training in survival actions is the main factor determining the favorable outcome of autonomous existence.

Risk factors

Climate. Adverse weather conditions: cold, heat, strong wind, rain, snow can reduce the limit of human survival many times over.

Thirst. Lack of water entails physical and mental suffering, general overheating of the body, rapidly developing thermal and sunstroke, dehydration in the desert - inevitable death.

Hunger. Prolonged lack of food depresses a person morally, weakens physically, increases the impact on the body of adverse environmental factors.

Fear. Reduces the body's resistance to thirst, hunger, climatic factors, leads to the adoption of erroneous decisions, provokes panic, mental breakdowns.

Overwork. It appears as a result of strenuous physical activities, insufficient food supply, difficult climatic and geographical conditions, due to the lack of proper rest.

Natural disasters: hurricanes, tornadoes, snowstorms, sandstorms, fires, avalanches, mudflows, floods, thunderstorms.

Diseases. The greatest threat is posed by injuries, diseases associated with exposure to climatic conditions, and poisoning. But we should not forget that in an emergency, any neglected callus or microtrauma can lead to a tragic outcome.

Survival Factors

Will to live. With a short-term external threat, a person acts on a sensual level, obeying the instinct of self-preservation. Bounces off a falling tree, clings to stationary objects when falling. Another thing is long-term survival. Sooner or later, a critical moment comes when exorbitant physical, mental stress and the seeming senselessness of further resistance suppress the will. A person is seized by passivity, indifference. He is no longer afraid of the possible tragic consequences of ill-conceived overnight stays, risky crossings. He does not believe in the possibility of salvation and therefore perishes without exhausting his reserves of strength to the end.

Survival, based only on the biological laws of self-preservation, is short-lived. It is characterized by rapidly developing mental disorders and hysterical behavioral reactions. The desire to survive must be conscious and purposeful. You can call it the will to live. Any skill and knowledge becomes meaningless if a person resigns himself to fate. Long-term survival is ensured not by the spontaneous desire “I don’t want to die”, but by the goal set – “I must survive!”. The desire to survive is not an instinct, but a conscious necessity! Survival tool - various standard and homemade emergency kits and emergency supplies (for example, a survival knife). If you are going on a dangerous journey, you need to complete emergency kits in advance, based on the specific conditions of the trip, terrain, time of year, and the number of participants. All items must be tested in practice, repeatedly checked, duplicated if necessary. General physical preparation does not require comments. Psychological preparation consists of the sum of such concepts as the psychological balance of each member of the group, the psychological compatibility of the participants, the similarity of the group, the real idea of ​​the conditions of the future route, training trips that are close in terms of loads and climatic and geographical conditions to the real upcoming ones (or better twice exceeding them). Of no small importance is the correct organization of rescue work in a group, a clear distribution of duties in marching and emergency modes. Everyone should know what to do in the event of a threat of an emergency.

Naturally, the above list is far from exhausting all the factors that ensure long-term survival. Once in an emergency, first of all, it is necessary to decide what tactics should be followed - active (independent exit to people) or passive (waiting for help). With passive survival, when there is absolute certainty that the missing person or group is being sought, that the rescuers know their whereabouts, and if there is a non-transportable victim among you, you should immediately start building a capital camp, installing emergency signals around the camp, providing food on the spot.

Life support. Assessing the situation and making an informed decision

How to behave in extreme cases? Let's start with the basics and remember the key word for this situation "SURVIVAL":

S - assess the situation, recognize dangers, look for ways out of a hopeless situation.

U - excessive haste harms, but make decisions quickly.

R - remember where you are, determine your location.

V - conquer fear and panic, constantly control yourself, be persistent, but if necessary - obey.

I - improvise, be creative.

V - cherish the means of existence, recognize the limits of your capabilities.

A - act like a local, know how to evaluate people.

L - learn to do everything yourself, be independent and independent.

A group of people. First of all, it is necessary to choose an elder, a person who knows and is able to take all the necessary measures aimed at survival. If your group takes the following tips into account, then the chances of being rescued and returning home will increase significantly. Should:

Decisions are made only by the senior of the group, regardless of the situation;

Follow the orders of the senior group only;

To develop a sense of mutual assistance in the group.

All this will help to organize the activities of the group so that the best way ensure survival.

First of all, it is necessary to assess the current situation, which in turn consists of an assessment of the factors affecting survival.

The health status of group members, physical and mental condition;

The impact of the external environment (air temperature and the state of atmospheric conditions in general, terrain, vegetation, the presence and proximity of water sources, etc.).

Availability of emergency supplies of food, water and emergency equipment.

Provide self- and mutual assistance (if necessary) and draw up an action plan based on specific conditions, which should include:

Carrying out orientation on the ground and determining your location;

Organization of a temporary camp. Choice suitable place for the construction of a shelter, taking into account the relief, vegetation, water sources, etc. Determination of the place of cooking, food storage, placement of a latrine, location of signal fires;

Provision of communication and signaling, preparation of radio equipment, operation and maintenance of them;

Distribution of responsibilities among group members;

Establishment of duty, tasks of duty officers and determination of the order of duty;

Preparation of visual signaling means;

As a result, an optimal mode of behavior in the current situation should be developed.

Help from local residents.

In most areas where a person or group of people injured in a disaster may be, there are always local residents. If you find yourself in a civilized country, the locals will always come to your aid and do everything necessary to get you home as soon as possible.

To enlist the support of local residents, be guided by the following:

It is better if the locals make contact first;

Deal on all matters with a recognized leader or leader; - Show friendliness, courtesy and patience. Don't show that you are afraid;

Treat them like human beings;

Respect their local customs and habits;

Respect the personal property of local residents; treat women with special respect;

Learn from the locals how to hunt and get food and water. Heed their advice regarding dangers;

Avoid physical contact with them, but in a way that is imperceptible to them;

Leave a good impression of yourself. Other people after you may need the same help.

When conducting RPS, rescuers often have to perform tasks far from populated areas, spend several days in the “field conditions”, and face a variety of extreme situations which imposes additional requirements on their ability to work in these conditions. Solid knowledge in various fields, the ability to use them in any conditions are the basis of survival. Going to the RPS, rescuers must, along with tools and protective equipment, have the following set of necessary items that can be useful in any climatic and geographical zone: a signal mirror, with which you can send a distress signal at a distance of 30-40 km; hunting matches, a candle or tablets of dry fuel for making a fire or heating a shelter; whistle for signaling; a large knife (machete) in a sheath, which can be used as a knife, ax, shovel, spear; a compass, a piece of thick foil and polyethylene, fishing equipment, signal cartridges, an emergency kit of medicines, a supply of water and food.

Signaling

Rescuers must know and be able to put into practice special signals. Rescuers can use fire smoke during the day and bright lights at night to indicate their location. If you throw rubber, pieces of insulation, oil rags into a fire, black smoke will be emitted, which is clearly visible in cloudy weather. For getting white smoke, which is clearly visible in clear weather, green leaves, fresh grass, and damp moss should be thrown into the fire.

To give a signal from the ground to an air vehicle (aircraft), a special signal mirror can be used (Fig. 1). It is necessary to keep it at a distance of 25-30 cm from the face and look through the sighting hole at the plane; turning the mirror, match the light spot with the sighting hole. In the absence of a signal mirror, objects with shiny surfaces can be used. For sighting, you need to make a hole in the center of the object. The light beam must be sent along the entire horizon line, even in cases where the noise of the aircraft engine is not heard.

Rice. 1 Special signal mirror.

At night, the light of a hand-held electric flashlight, a torch, a fire can be used for signaling.

A fire built on a raft is one of the distress signals.

Good means of signaling are brightly colored objects and a special coloring powder (fluorescein, uranine), which are scattered on snow, earth, water, and ice when an aircraft (helicopter) approaches.

In some cases, sound signals (shout, shot, knock), signal rockets, smoke bombs can be used.

One of the latest developments in target designation is a small rubber Balloon with a nylon sheath, covered with four luminous colors, under which a light bulb flashes at night; the light from it is clearly visible at a distance of 4-5 km. Before launch, the balloon is filled with helium from a small capsule and held at a height of 90 m by a nylon cable. The mass of the kit is 1.5 kg.

In order to facilitate the search, it is advisable to use the International code table of air signals "Ground - Air" (Fig. 2). Its signs can be laid out with the help of improvised means (equipment, clothing, stones, trees), directly by people who must lie down on the ground, snow, ice, trampled on the snow.

Along with the ability to give signals, rescuers must be able to work and live in the field, taking into account meteorological (weather) factors. Monitoring the state and forecasting of the weather is carried out by special meteorological services. Weather information is transmitted by means of communication, in special reports, is applied to maps using conventional signs.

In the absence of information about the weather, rescuers must be able to determine and predict it according to local characteristics. To obtain reliable information, it is advisable to make a weather forecast simultaneously for several of them.

Cloudiness is decreasing.

Frost appears on the grass land and trees.

The blue spots over the forest weaken and soon completely disappear.

The weather imposes certain requirements on the organization of a bivouac, temporary housing, life and rest during multi-day RPS. With this in mind, rescuers organize a bivouac. It should be located in avalanche-safe and rock-fall-safe areas, close to a source of drinking water, have a supply of deadwood or firewood. It is impossible to arrange a bivouac in the dried up beds of mountain rivers, near the shallows, in dense shrubs, coniferous thickets, near dry, hollow, rotten trees, in thickets of flowering rhododendron. After removing stones, branches, debris from the site and leveling it, rescuers can proceed with setting up the tent. (Fig. 3)

Tents differ in design features, capacity, material. Despite this, they are all designed to protect a person from cold, rain, wind, dampness, and insects.

The procedure for setting up the tent is as follows:

Expand the tent;

Stretch and secure the bottom;

Install the racks and tighten the guys;

Fasten the exit and tighten the roof braces;

Eliminate creases on the roof by tightening (loosening) the braces;

Dig a ditch around the tent with a width and depth of 8-10 cm to drain water in case of rain.

Under the bottom of the tent, you can put dry leaves, grass, ferns, reeds, moss. When setting up a tent on snow (ice), empty backpacks, ropes, windbreakers, blankets, and foam rubber should be placed on the floor.

The pegs are hammered at an angle of 45° to the ground to a depth of 20-25 cm. Trees, stones, ledges can be used to secure the tent. The back wall of the tent must be placed in the direction of the prevailing winds.

In the absence of a tent, you can spend the night under a piece of tarpaulin, polyethylene, or equip a hut from improvised materials (branches, logs, spruce branches, leaves, reeds). It is installed on a flat and dry place, in a clearing or the edge of a forest.

In winter, the campsite should be cleared of snow and ice.

Fig.3 Options for setting up tents.

In snowy winter conditions, rescuers must be able to arrange shelters in the snow. The simplest of them is a hole dug around a tree, the size of which depends on the number of people. From above, the pit must be closed with branches, dense cloth, covered with snow for better thermal insulation. You can build a snow cave, a snow dugout, a snow trench. When entering a snow shelter, you should clean your clothes from snow and dirt, take a shovel or knife with you, which can be used to make ventilation holes and a passage in case of snow collapse.

For cooking, heating, drying clothes, signaling, rescuers use fires of the following types: "hut", "well" ("log house"), "taiga", "nodya", "fireplace", "Polynesian", "star", " pyramid". "Shalash" is convenient for making tea quickly and lighting the camp. This fire is very "gluttonous", it burns hot. “Well” (“log house”) is kindled, if you need to cook food in a large bowl, dry wet clothes. In the "well" the fuel burns out more slowly than in the "hut"; a lot of coals are formed, which create a high temperature. On the "taiga" you can cook food at the same time in several pots. On one thick log (approximately 20 cm thick), several thinner dry logs are placed, which approach each other at an angle of 30 °. necessarily on the leeward side. Fuel burns for a long time. Near such a fire you can stay for the night. "Nodya" is good for cooking food, heating during the night, drying clothes and shoes. Two dry logs up to 3 m long are placed close to each other, flammable fuel (thin dry twigs, birch bark) is ignited in the gap between them, after which a third dry log of the same length and 20-25 cm thick is placed on top. To prevent the logs from rolling out, with flyers are driven into the ground on two sides of them. They will simultaneously serve as supports for the stick on which the bowlers are hung. The “nodya” flares up slowly, but it burns with an even flame for several hours. Any fire must be made only after careful preparation of the site: collection of dry grass and deadwood, making a deepening in the ground, fencing with stones the place where it will be bred. The fuel for the fire is dry forest, grass, reeds, shrubs. It has been noticed that burning spruce, pine, cedar, chestnut, larch give a lot of sparks. Oak, maple, elm, beech burn quietly. To quickly kindle a fire, kindling is needed (birch bark, small dry branches and firewood, a piece of rubber, paper, dry fuel). It is tightly packed with a “hut” or “well”. To make the kindling light up better, put a piece of candle in it or put dry alcohol. Thicker dry branches are laid around the kindling, then thick firewood. In wet weather or during rain, the fire must be covered with a tarpaulin, a backpack, a thick cloth. You can light a fire with matches, a lighter, sunlight and magnifying glass, friction, flint, shot. In the latter case, you need:

Open the cartridge and leave only gunpowder in it;

Lay dry cotton wool on top of the gunpowder;

Shoot at the ground, while observing safety measures;

The smoldering cotton wool will ensure the kindling of the fire.

For making a fire in winter time it is necessary to clear the snow to the ground or build a deck of thick logs on the snow, otherwise the melted snow will extinguish the fire. To prevent a fire from causing a fire, it should not be made under low tree branches, near flammable objects, on the leeward side, relative to the bivouac, on peat bogs, near reeds and reeds, dry grass, moss, in spruce and pine undergrowth. In these places, the fire spreads from high speed and difficult to extinguish. In order to prevent the spread of fire, the fire must be surrounded by a ditch or stones. The safe distance from the fire to the tent is 10m. To dry clothes, shoes, equipment near the fire, they should be hung on poles or ropes located on the leeward side at a sufficient distance from the fire. An obligatory rule is to extinguish the fire (with water, earth, snow) when leaving the bivouac. Successful fulfillment by rescuers of the tasks assigned to them is possible only if the body restores and maintains high mental and physical performance throughout the entire period of work. This is based on a balanced diet. It is important not only the correct ratio of proteins, fats and carbohydrates in food, but also the mandatory presence of vitamins and other biologically active substances in it. active substances The rescuer's daily diet should include at least 1.5 g of protein per kilogram of body weight, almost the same amount of fat and 4 times more carbohydrates, as well as about 30-35 g of table salt, vitamins, water, etc.

Even today, it is not uncommon for a person, as a result of the prevailing circumstances, to find himself in conditions of autonomous existence, the favorable outcome of which largely depends on his psychophysiological qualities, sound knowledge of the basics of survival and other factors. The main task of a person in an autonomous situation is to survive. The word "survive" has always been used in a very specific sense - "stay alive, survive, protect yourself from death." Survival is understood as active, intelligent actions aimed at preserving life, health and performance in an autonomous existence. But an extreme situation is easier to prevent than to get out of it. Therefore, do not go anywhere without telling someone your route and the approximate time of return, know the area of ​​\u200b\u200btravel, when setting off, take with you: a first aid kit, comfortable shoes and clothes for the season, a cell phone / pager / walkie-talkie. And offline:

To survive you need:

1. OVERCOME FEAR.

Under any circumstances, the survival of a person primarily depends on himself. It's not just about his skills. More often than not, a situation of autonomy arises unexpectedly, and the first reaction of anyone who finds himself in a dangerous situation is fear. But the obligatory conditions for the successful overcoming of all difficulties in an autonomous situation are the manifestation of will, perseverance, and competent action. Panic and fear dramatically reduce the chances of salvation.

With a short-term external threat, a person acts on a sensual level, obeying the instinct of self-preservation: bounces off a falling tree, clings to immovable objects when falling, tries to stay on the surface of the water in case of a threat of drowning. There is no need to talk about some kind of will to live in such cases. Another thing is long-term survival. In the conditions of autonomous existence, sooner or later, a critical moment comes when exorbitant physical and mental stress, the seeming senselessness of further resistance suppress the will. A person is seized by passivity, indifference. He is no longer afraid of the possible tragic consequences of ill-conceived overnight stays, risky crossings. He does not believe in the possibility of salvation and therefore perishes without exhausting his reserves of strength to the end, without using food supplies.

Survival, based only on the biological laws of self-preservation, is short-lived. It is characterized by rapidly developing mental disorders and hysterical behavioral reactions. The desire to survive must be conscious and purposeful, and must be dictated not by instinct, but by conscious necessity.

Fear is an emotional response to danger that can be accompanied by physical sensations such as trembling, rapid breathing, and a strong heartbeat. This is a natural reaction, and it is characteristic of every normal person. It is the fear for one's life that causes the desire to act in the name of one's own salvation. If a person knows how to act, fear sharpens the reaction, activates thinking. But if he has no idea what to do, feels pain or weakness from blood loss, then fear can lead to stress - excessive tension, inhibition of thoughts and actions. These sensations can be so intense that sudden intense fear can lead to death. There are various ways to overcome fear. If a person is familiar with the auto-training technique, then he will be able to relax, calm down, and analyze the situation impartially in a matter of minutes. If not, then thinking about something else will help the person relax and be distracted. Breathing exercises also have a good effect. You need to take a few deep breaths. When a person experiences fear or stress, his pulse speeds up, and he begins to breathe very quickly. Forcing yourself to breathe slowly means convincing the body that the stress is passing, whether it has passed or not.

In addition, a person cannot act successfully if he does not have a clear goal and a plan to achieve it. Sometimes it seems that professional rescuers, pilots, military difficult situations act without thinking. But this is not so: they just have a ready-made, often already proven plan, or even several options. At first, it may seem to a person that he knows nothing and can do nothing. But one has only to divide the situation and tasks into its component parts, as it turns out that much is within his power. in the surest way to overcome fear and confusion is the organization of systematic actions to ensure survival. To do this, a person needs to set himself a clear attitude to act in a possible extreme situation.

2. HELP THE VICTIMS

(including self help)

It is good to have a first aid kit to help, so when you go on a trip, it is better to take it with you. The set of necessary medicines depends on climatic conditions. For example, in the desert you need serum against snake venom, sunburn cream, etc. In a tropical first-aid kit, there should be repellent against leeches, insects, powder for fungal diseases, and an antimalarial drug. Every first aid kit should have:

• individual dressing package for each
• bandages
• sterile wipes
• plaster (bactericidal and simple)
• potassium permanganate
• medical alcohol
• syringe tubes of morphine or other pain medication
• broad spectrum antibiotics
• nitroglycerine
• corvalol/validol
• caffeine solution
• adrenaline solution
• synthomycin emulsion (for burns / frostbite)
• tetracycline ointment (for eye inflammation)
• pantocide (for water disinfection)

You should have medicines individually selected for everyone in sufficient quantities (at least the required minimum). Names and uses of medicines must be signed with indelible pencil/ink. Pack the first-aid kit carefully, excluding the possibility of damage to medicines. Scissors or a scalpel, if not available, can be replaced with a disinfected razor blade.

Must be able to use medicinal herbs, as well as

distinguish them from poisonous plants. Only well-known herbs can be used, therefore, when going to another climatic zone, it is better to remember local poisonous plants and at least 5 medicinal / edible ones in advance. For example, strawberries, celery, elm bark help with fever. Lilac, sunflower, nettle tincture with garlic, wild rose, willow bark help against malaria.

To provide medical assistance immediately after an accident or if a long autonomous existence is necessary, skills are needed, therefore everyone should be able to provide first aid. With autonomous survival, the most likely:

• BURN. The burnt place should be cooled, wiped with an alcohol solution, apply a dry bandage. The affected area can be rubbed with a decoction of oak bark, raw potatoes, urine. Do not lubricate the burn with oil, do not open the resulting bubbles.
• BLEEDING. Press the damaged vessel (artery - from above, except for the arteries of the head, neck) or apply a tourniquet / pressure bandage from improvised means (except for wires, ropes, cords). Treat the wound with iodine / hydrogen peroxide / brilliant green and close with a plaster / bandage. You can apply viburnum berries, wild rose, plantain, aloe to a bleeding wound. For purulent wounds, a decoction of burdock is applied. The tourniquet can not be kept longer than 1.5 hours in summer and 30 minutes. in winter.
• FRACTURES / DISTRUCTIONS. The injured limb must be immobilized (for which a splint or stick/ski/board is used). Pain can be reduced by applying ice. Finely chopped onion helps (with dislocations). You can not take painkillers, you can not try to set the limb yourself.
• CPR/HEART MASSAGE necessary in case of clinical death (no pulse and breathing or convulsive breathing, pupils do not react to light). The caregiver inhales air into the mouth / nose of the victim about 24 times per minute. The nose / mouth of the victim should be clamped. Circulation can be restored by pressing on the chest. The patient should lie on a hard surface, unbutton the clothes. Death occurs within 5 minutes. after clinical death, but resuscitation should be continued for 20-30 minutes. Sometimes it works.
• FAINTING. If breathing and cardiac activity are not disturbed, it is enough to unfasten the clothes, bring a swab with ammonia to the nose, and lay the person down so that the head is lower than the legs.

In case of any injuries, it is best to try to deliver the victim to a doctor.

3. ORIENTATE ON THE TERRAIN.

When traveling in unfamiliar terrain, it is best to have a map. If it is not there, you can navigate without it.

The sides of the horizon can be determined by a compass, celestial bodies, according to some signs of local objects. When unbraked, the compass needle is set with its northern end in the direction of the north magnetic pole, respectively, the other end of the arrow will point south. The compass has a circular scale (limb), which is divided into 120 divisions. The price of each division is 3 or 0-50. The scale has a double digit. The inner one is applied clockwise from 0 to 360 degrees in 15 degrees. For sighting on local objects and taking readings on the compass scale, a sighting device and a reading pointer are fixed on the rotating compass ring. When working with a compass, you should always remember that strong electromagnetic fields or closely spaced metal objects deviate the magnetic needle from its correct position. Therefore, when determining compass directions, it is necessary to move 40-50 m away from power lines, railway tracks, combat vehicles and other large metal objects.

You can determine the sides of the horizon by celestial bodies:

• according to the sun: the sun at 7 o'clock in the morning is in the East, at 13 o'clock in the South, at 19 o'clock in the West;
• by the sun and the clock with arrows. To determine the direction in this way, it is necessary to hold the clock in a horizontal position and turn it so that hour hand its sharp end was directed towards the sun. A straight line dividing the angle between the hour hand and the direction of the number 1 indicates South.
• By moving the shadow from a vertically placed stick, it will show the approximate East-West direction;

At night, the sides of the horizon can be determined by the North Star. To do this, you need to find the constellation Ursa Major with a characteristic arrangement of stars in the form of a bucket with a handle. An imaginary line is drawn through the last two stars of the bucket, and the distance between these stars is plotted on it 5 times. At the end of the fifth segment there will be a bright star - Polaris. The direction to it will correspond to the direction to the north. The sides of the horizon can be determined by some signs of local objects.

1. The bark of most trees is rougher on the north side.
2. Stones, trees, wooden, tiled and slate roofs on the north side are covered with moss earlier and more abundantly. On coniferous trees, resin is more abundant on the south side. It is useless to look for all these signs on the trees among the thicket. But they are clearly expressed on a separate tree in the middle of a clearing or at the edge.
3. Anthills are located on the south side of trees and stones.
4. Snow melts faster on the southern slopes of the hills and mountains.

Magnetic azimuth is used - a horizontal angle measured clockwise from 0 degrees to 360 from the north direction of the magnetic meridian to the direction to be determined.

For determining magnetic azimuth it is necessary: ​​to stand facing the observed object (landmark), release the brake of the compass needle and, having given the compass a horizontal position, turn it until the northern end of the arrow is against the zero division of the scale. While holding the compass in an oriented position, turn the rotating cover to direct the line of sight passing through the slot and the front sight in a given direction to a given object. The average error in measuring the azimuth with a compass is about 2 degrees. Movement, during which a given direction is maintained and an accurate exit to the designated point is carried out, is called movement in azimuth. Movement along azimuths is used mainly in the forest, in the desert, at night, in fog and tundra, and other terrain and visibility conditions that make visual orientation difficult. When moving in azimuth, at each turning point of the route, starting from the initial one, they find the desired direction of the path on the ground using the compass and move along it, counting the distance traveled. When moving in azimuth, it becomes necessary to bypass obstacles that cannot be overcome directly. In doing so, proceed as follows. They notice a landmark on the opposite side of the obstacle in the direction of movement, determine the distance to it, add it to the distance traveled. After that, having bypassed the obstacle, they go to the chosen landmark and determine the direction of movement by the compass.

In mountainous terrain, landmarks are chosen so that they are distributed in the direction of action of the subunits not only along the front and in depth, but also in height. In a forest area, maintaining a route of movement passing along dirt roads and clearings requires the ability to accurately recognize on the ground those of them along which the path selected on the map passes. At the same time, it should be taken into account that forest roads are often hardly visible on the ground, and some of them may not be shown on the maps. At the same time, you can find roads that are not shown on the map, but at the same time they are well traveled. As landmarks in the forest, roads, clearings, intersections, and forks in roads and clearings, rivers and streams, glades crossing the route of movement are used. Clearings are usually cut in mutually perpendicular directions, as a rule, in a northerly direction, respectively, west-east.

There are several ways to measure angles and distances on the ground.

1. Measuring angles on the ground with binoculars.

In the field of view of the binoculars there are two perpendicular goniometric scales for measuring horizontal and vertical angles. The value (price) of one large division corresponds to 0-10, and the small one - 0-05. To measure the angle between two directions, looking through binoculars, combine any stroke of the angular scale with one of these directions and count the number of divisions to the second direction and count the number of divisions to the second direction. Multiplying, then, this reading by the division price, we get the value of the measured angle in "thousandths".

1. Measuring angles with a ruler.

In some conditions of the situation, a situation may arise when there is no binoculars at hand, then it can measure angular values ​​using a ruler. To do this, you need to hold the ruler in front of you at eye level at a distance of 50 cm. One millimeter of the ruler will correspond to 0-02. The accuracy of measuring angles in this way depends on the ability to maintain distances from the eyes (50 cm), which requires some training.

3. Measuring angles with improvised means.

Instead of a ruler, you can use various objects whose sizes are well known: a matchbox, a pencil, fingers and palms of your hands. You can measure angles with a compass. Measuring angles on the ground is a preparation for determining distances on the ground. Various methods and instruments are used to determine distances on the ground. Often people are forced to determine distances different ways: visually or according to the measured angular magnitude of objects on the ground, according to the speedometer of the car, measured in steps, according to the average speed of movement.

EYE - the main way and the easiest way to determine distances, available to everyone. This method does not give high accuracy in determining distances, but with some training, you can achieve an accuracy of up to 10 m. To develop your eye, you need to constantly practice in determining distances on the ground.

One way to measure distances on the ground is to use known distances on the ground (power lines - distance between supports, distance between communication lines, etc.).

For a rough estimate of distances on the ground, the following data can be used:

For each person, this table can be refined by him.

Determination of distances by the angular dimensions of objects is one of the main methods for determining distances and has a fairly high accuracy. To determine distances by angular values, it is necessary to know the linear dimensions of a local object, determine the angle at which it is visible, and then determine the distance to this object using the formula:

D= 1000*B

At

In this formula: D - range

H - height

Y - the angle in "thousandths" under which the object is visible; 1000 - constant coefficient.

Measuring distances in steps.

It is necessary for each commander to know that a person's step is approximately equal to 0.75 m, but it is inconvenient to make calculations at this size and, therefore, it is assumed that a couple of steps are equal to 1.5 m. In this case, it is much more convenient to carry out calculations. With this method, the accuracy of determining distances can be 98%.

It is advisable to determine distances by the speed of movement and by the speedometer of the car in cases of movement. One of the ways to determine distances can be a method by sound, flashes. Knowing that the speed of sound in air is 330 m/s i.e. rounded 1 km. For 3 sec. you can determine the distance by doing a little calculation. In some cases, the distance can be determined by ear, i.e. listening to different sounds. From the experience of assessing the audibility of various sounds, it becomes clear that:

• walking on a dirt road can be heard at a distance of 300 m, and when driving on a highway - 600 m.
• movement of cars on a dirt road - 500 m, on a highway - up to 1000 m.
• Loud screams - 0.5 - 1 km.
• Driving stakes, felling trees - 300-500m.

The given data is very approximate and depends on the hearing of the person.

At the heart of any method of determining distances is the ability to select landmarks on the ground and use them as marks indicating the desired directions, points and boundaries. Landmarks are usually called well-visible objects on the ground and relief details, relative to which they determine their location, direction of movement and indicate the position of targets and other objects. Landmarks are chosen as evenly as possible. The selected landmarks can be numbered by choosing a direction, or given a conventional name. To indicate your location on the ground relative to a landmark, determine the direction and distance from it.

1. TRY TO GET OUT

Getting out as soon as possible is especially important if there are wounded among the lost or if the lost are in a dangerous zone. It is difficult to move among the rubble and windbreaks, in thick forests overgrown with shrubs. The apparent similarity of the environment - trees, terrain folds, etc. - can completely disorient a person, and he often moves in circles, unaware of his mistake.

In order to maintain the chosen direction, some well-marked landmark is usually marked every 100-150 m of the route. This is especially important if the path is blocked by a blockage or a dense thicket of shrubs, which force you to deviate from the direct direction. Trying to go ahead is always fraught with injury, which will aggravate the already difficult situation of the person in distress. But it is especially difficult to make transitions in the swamp zone. It is not easy to find a safe walking path among the shifting green space.

Of particular danger in the swamp are the so-called windows - areas of clear water on the gray-green surface of the swamps. Sometimes their sizes reach tens of meters. It is necessary to overcome the swamp with the utmost care and be sure to arm yourself with a long, strong pole. It is held horizontally at chest level. Having failed, in no case should you flounder. It is necessary to get out slowly, leaning on the pole, without making sudden movements, trying to give the body a horizontal position. For a short rest when crossing the swamp, you can use outcrops of hard rock. Water obstacles, especially rivers with a fast current and a rocky bottom, are overcome without taking off their shoes, for greater stability. Before taking the next step, the bottom is probed with a pole. It is necessary to move obliquely, sideways to the current, so that the stream does not knock you down.

In winter, you can move along the beds of frozen rivers, while observing the necessary precautions. So, it must be remembered that the current usually destroys the ice from below, and it becomes especially thin under snowdrifts near steep banks, that in the channels of rivers with sandy shallows, streaks often form, which, when frozen, turn into a kind of dam. At the same time, water usually finds a way out along the coast under snowdrifts, near snags, rocks, where the current is faster.

In cold weather, the streaks soar, resembling the smoke of human habitation. But much more often, streaks are hidden under deep snow, and they are difficult to detect. Therefore, all obstacles river ice better bypass; in places where rivers bend, one must stay away from the steep bank, where the current is faster and therefore the ice is thinner.

Often after a river freezes, the water level drops so quickly that under thin ice pockets are formed, which pose a great danger to the pedestrian. On the ice, which seems not strong enough, and there is no other way, they crawl. In spring, the ice is thinnest in areas overgrown with sedge, near flooded bushes.

If there is no firm confidence in the ability to quickly get out of the situation, and the situation does not require immediate departure from the scene, it is better to stay in place, make a fire, build a shelter from improvised materials. This will help you to protect yourself well from the weather and keep your strength for a long time. In addition, in parking conditions it is much easier to get food. In some cases, this tactic will facilitate the actions of the search and rescue service, which received information about the incident in a particular area. Having made the decision to “stay in place”, you need to draw up a plan for further action, in which to provide for the necessary measures.

4BUILD A SHELTER

Organizing an overnight stay is hard work. First you need to find a suitable site. First of all, it must be dry. Secondly, it is best to settle down near the stream, in an open place, in order to always have a supply of water on hand.

The simplest shelter from wind and rain is made by linking individual elements of the base (frame) with thin spruce roots, willow branches, and tundra birch. Natural cavities in the steep bank of the river allow you to comfortably sit on them so that the place of sleep is between the fire and the vertical surface (cliff, rock), which serves as a heat reflector.

When preparing a place to sleep, two holes are dug - under the thigh and under the shoulder. You can spend the night on a bed of spruce branches in a deep hole dug or thawed to the ground with a large fire. Here, in the pit, one should keep the fire in the fire all night long in order to avoid a serious cold. In the winter taiga, where the thickness of the snow cover is significant, it is easier to arrange a shelter in a hole near a tree. V hard frost you can build a simple snow hut in loose snow. To do this, the snow is raked into a heap, its surface is compacted, watered and allowed to freeze. Then the snow is removed from the pile, and a small hole is made in the remaining dome for the chimney. A fire built inside melts the walls and makes the whole structure strong. Such a hut retains heat. You can not climb under clothes with your head, because from breathing the material becomes damp and freezes. It is better to cover the face with clothes that are easy to dry later. From a burning fire, an accumulation of carbon monoxide is possible and you need to take care of a constant influx of fresh air to the combustion center.

A canopy, a hut, a dugout, a tent can serve as a temporary shelter. The choice of the type of shelter will depend on the skill, ability, diligence and, of course, the physical condition of the people, since there is no shortage of building material. However, the more severe the weather, the more reliable and warmer the dwelling should be. Make sure that the future home is spacious enough. There is no need to adhere to the principle of "in close quarters, but not offended."

Before starting construction, it is necessary to clear the site well, and then, having estimated how much it will take building material, prepare it in advance: cut down the poles, chop the spruce branches, branches, collect moss, cut the bark. To make the pieces of bark sufficiently large and strong, deep vertical cuts are made on the larch trunk, up to the very wood, at a distance of 0.5-0.6 m from each other. After that, the strips are cut from above and below with large teeth of 10-12 centimeters in diameter, and then the bark is carefully peeled off with an ax or a machete knife.

Rice. 12. Chum tent

In the warm season, you can limit yourself to building a simple canopy (Fig. 10, B). Two one and a half meter stakes as thick as a hand with forks at the end are driven into the ground at a distance of 2.0-2.5 m from each other. A thick pole is laid on the forks - a load-bearing beam. 5-7 poles are leaned against it at an angle of approximately 45-60 ° and, having secured them with a rope or vine, a tarpaulin, parachute or any other fabric is pulled over it. The edges of the awning are bent from the sides of the canopy and tied to a beam laid in the base of the canopy. Litter is made from spruce branches or dry moss. The canopy is dug in with a shallow groove to protect it from water in case of rain.

A gable hut is more convenient for housing (Fig. 10, A and Fig. 11, B). After driving in the racks and laying the load-bearing beam on them, the poles are laid on it at an angle of 45-60 ° on both sides, and three or four poles are tied to each slope parallel to the ground - rafters. Then, starting from the bottom, spruce branches, branches with dense foliage or pieces of bark are laid on the rafters so that each subsequent layer, like a tile, covers the bottom one to about half. The front part, the entrance, can be hung with a piece of fabric, and the back part is covered with one or two poles and braided with spruce branches.

With a high snow cover at the foot of a large tree, you can dig a “snow trench” (Fig. 11, A). From above, the trench is covered with a tarpaulin or parachute cloth, and the bottom is lined with several layers of spruce branches.

1. GET FIRE

A fire in the conditions of autonomous existence is not only warm, it is dry clothes and shoes, hot water and food, protection from midges and an excellent signal for a search helicopter. And most importantly, a fire is an accumulator of vivacity, energy and vigorous activity. But before starting a fire, all measures should be taken to prevent a forest fire. This is especially important during dry, hot seasons. A place for a fire is chosen away from coniferous, and especially withered trees. Thoroughly clean the space for a meter and a half around from dry grass, moss and shrubs. If the soil is peaty, then, so that the fire does not penetrate the grass cover and cause the peat to ignite, a “cushion” of sand or earth is poured.

In winter, with a high snow cover, the snow is carefully trampled down, and then a platform is built from several tree trunks.

To get fire you need use a flint and flint, a piece of flint. Any steel object can serve as a flint and flint, in extreme cases, the same iron pyrites. Fire is struck by sliding blows on flint so that sparks fall on tinder - dry moss, crushed dry leaves, newspaper, cotton wool, etc. Fire can be mined friction. For this purpose, a bow, a drill and a support are made: a bow - from a dead trunk of a young birch or hazel 2-3 cm thick and a piece of rope as a bowstring; drill - from a pine stick 25 - 30 cm long, pencil-thick, pointed at one end; the support is cleaned of bark and a hole 1-1.5 cm deep is drilled with a knife. The drill, wrapped once with a bowstring, is inserted with a sharp end into the hole, around which tinder is laid. Then, pressing the drill with the palm of the left hand, the right hand quickly moves the bow perpendicular to the drill. In order not to damage the palm, a gasket is placed between it and the drill from a piece of cloth, tree bark, or a glove is put on. As soon as the tinder smolders, it must be blown up and put into kindling prepared in advance. To achieve success, you should remember three rules: the tinder must be dry, you must act in strict sequence, and most importantly, show patience and perseverance. For cooking and drying clothes, the “hut” fire is most convenient, giving a large, even flame, or “starry” of 5-8 dry trunks arranged star-shaped. They are set on fire in the center and shifted as they burn. For heating during an overnight stay or in cold weather, 3-4 thinner stems are placed in a fan on a thick trunk. Such a fire is called taiga. For heating for a long time they use a fire Node. Two dry trunks are laid one on top of the other and fixed at the ends on both sides with stakes. Wedges are inserted between the trunks and kindling is laid in the clearance. As the wood burns, the ashes and ashes are cleaned from time to time. Leaving the parking lot, smoldering coals must be carefully extinguished by filling them with water or throwing earth. To make fire in the absence of matches or a lighter, you can use one of the methods that have long been known to mankind before their invention.

1. GET FOOD AND WATER

A person who finds himself in conditions of autonomous existence must take the most energetic measures to provide himself with food by collecting edible wild plants, fishing, hunting, i.e. use everything that nature gives. Over 2,000 plants grow on the territory of our country, partially or completely suitable for food. When collecting plant gifts you have to be careful. About 2% of plants can cause severe and even fatal poisoning. To prevent poisoning, it is necessary to distinguish between such poisonous plants as the crow's eye, wolf's bast, poisonous milestone (hemlock), bitter henbane, etc. Food poisoning is caused by poisonous substances contained in some mushrooms: pale grebe, fly agaric, false honey agaric, false chanterelle, etc. It is better to refrain from eating unfamiliar plants, berries, mushrooms. When forced to use them for food, it is recommended to eat no more than 1-2 g of food mass at a time, if possible, drinking plenty of water (vegetable poison contained in such a proportion will not cause serious harm to the body). Wait 1-2 hours. If there are no signs of poisoning (nausea, vomiting, abdominal pain, dizziness, intestinal disorders), you can eat an additional 10-15 g. After a day, you can eat without restrictions. An indirect sign of the edibility of a plant can be: fruits pecked by birds; many seeds, scraps of peel at the foot of fruit trees; bird droppings on branches, trunks; plants gnawed by animals; fruits found in nests and burrows. Unfamiliar fruits, bulbs, tubers, etc. it is desirable to boil. Cooking destroys many organic poisons.

There are many trees and shrubs that give edible fruits: mountain ash, actinidia, honeysuckle, wild rose, etc. From edible wild plants, you can use the stems and leaves of hogweed and angelica, arrowhead tubers, cattail rhizome, as well as a variety of edible mushrooms. In food, you can use garden or grape snails. They are scalded with boiling water or fried. They taste like mushrooms. Snails without shells - slugs, also need to be boiled or fried first.

Pupae of solitary bees in the stems of blackberries, raspberries or elderberries, pupae of the woodcutter beetle, which can be found in stumps, logs, oak logs, are suitable for food. The larvae can be eaten after gutting, cutting off the back end and rinsing in water. At the bottom of rivers and lakes in winter there are bivalve shells of toothless and barley, quite suitable for food. In stagnant water, there are snails with a curled shell of coils and pond snails. Ant pupae or, as they are called, ant eggs are a high-calorie food source. In the warm season, ant eggs, similar to white or yellowish rice grains, are found in abundance in anthills near the surface. To collect "prey" near the anthill, in a site lit by the sun, they clear a site 1 X 1 m and spread a piece of cloth on it, wrapping the edges and placing a few small branches under the bottom. Then the upper part of the anthill is torn off and scattered in a thin layer on the fabric. After 20-30 minutes, the ants drag all the pupae under the wrapped edges of the fabric, saving them from the sun. In conditions of autonomous existence fishing, perhaps the most affordable way to provide yourself with food. Fish has a higher energy value than vegetable fruits, and is less labor intensive than hunting. Fishing tackle can be made from improvised materials: fishing line - from loose shoelaces, thread pulled out of clothes, untwisted rope, hooks - from pins, earrings, hairpins from badges, "invisible", and spinners - from metal and mother-of-pearl buttons, coins and etc.

It is permissible to eat fish meat raw, but it is better to cut it into narrow strips, dry them in the sun, so it will become tastier and last longer. In order to avoid fish poisoning, certain rules must be observed. You can not eat fish covered with spines, spikes, sharp growths, skin ulcers, fish that are not covered with scales, devoid of lateral fins, having neo

5.1.1. The concept of human habitat

A person during his life is surrounded by objects of the material world that make up the human environment, or the human habitat (habitat). It consists of inanimate (earth, water, plants, buildings, tools, etc.) and animate (people, animals and etc.) objects.

The content of the human habitat depends on the place, time and conditions. The human habitat in the southern regions of the country differs from that in the northern regions due to differences in climatic conditions. At the same time, the climate itself changes over time, the temperature of the atmospheric air - during the year and day. Differences in the habitat in everyday life and at work are especially significant.

The living environment of a person is determined by the conditions of a person’s stay in his home, in the bosom of nature (rest, work on a personal plot, etc.), in in public places, on the street, in transport, if this is not related to the performance of a person's official duties.

The production environment of a person is determined by the working conditions of a person in production, in an organization, or an institution. In most cases, the conditions of the production environment are less favorable for humans than domestic ones. However, in some cases, the impact on a person of some factors of these environments may be close. For example, the effect of solar radiation on a person resting under the sun is close to that of a worker doing outdoor work at the same latitudes and under the same weather conditions.

In the process of human life, the environment has a certain influence on him. For example, atmospheric air can heat or cool the human body, a falling object can cause injury. Long-term environmental impacts of the same nature eventually cause certain changes in the human body, and under their influence a person adapts to the environment, changing physiologically and psychologically.

From the point of view of human impact, the environment can be represented as consisting of factors that are divided into natural (natural) and anthropogenic, or artificial, generated by human activity. In the historical aspect, in the beginning there were only natural factors. Later, anthropogenic factors began to join them.

A number of human habitat factors can have an adverse effect on it.

Natural unfavorable factors are essential in the domestic environment. For everyday life, for example, the climatic factor is of great importance, which largely determines the conditions of indoor living and outdoor recreation. Of great importance is the aquatic environment, which supplies a person with drinking water, irrigates gardens, but at the same time can bring with it great destruction and casualties (floods, storms at sea, etc.). Equally important in everyday life are the effects of harmful natural substances (dust, poisonous gases, etc.), the temperature factor (burns, frostbite), etc.

With the development of human society, the role of anthropogenic adverse factors increases. At present, they are as important as natural factors. Suffice it to recall the electric shock, the fall of people with their own erected structures, gas poisoning, including carbon monoxide, and many other examples. In the mining industry, for example, the main dangers are rock falls in workings as a result of human activity in the bowels of the earth, as well as vehicles in mines: they account for about half of the fatal accidents that occur in coal mines.

What environmental factors are unfavorable for the human body? When answering this question, it is necessary to proceed from the following.

The development of the human body adapted (adapted) it to certain average values ​​of environmental factors and to a certain range of their change relative to average values. But in the course of the life of an organism, it is also possible for the values ​​of environmental factors to go beyond the usual limits for it. The body is not accustomed to such values. The more the factor values ​​deviate from the usual limits, the more unfavorable it is. We come to the conclusion that an environmental factor is unfavorable, the values ​​of which periodically, but not often, go beyond the range of its values ​​habitual for a given organism. For example, for the inhabitants of the middle latitudes of Russia, the outside air temperature is from +20°C to -20°C. Their body has adapted to this temperature diagnosis and in such temperature conditions it functions normally, on average, a person feels comfort (convenience). The temperature of + 30 ° C or - 25 ° C is already perceived uncomfortable, and with large deviations from the usual temperature range, adverse consequences can occur in a person. Therefore, in this example, temperatures above +25°C and below -20°C can be considered as unfavorable values ​​for the factor temperatures. If deviations in the range from +25°С to -20°С are regular, but small (for example, deviations from the upper limit of usual temperatures by +5°С and from the lower limit by -5°С), a person gets used to them and they expand the range of comfortable temperatures. Hence the conclusion follows: in principle, any environmental factor can be unfavorable. For example, oxygen in atmospheric air is essential for human life. Its content in the air is about 21%, and the human body is adapted to such a content. With a significant decrease (increase) in the oxygen content in the air, a person begins to change the functions of a number of organs, which can lead to serious disorders and even death. Thus, oxygen is a favorable factor for human life, if its content is within 21%, with a significant deficiency or excess, it becomes an unfavorable factor. A similar example can be given with atmospheric pressure: normal atmospheric pressure is favorable for a person, its values, which differ significantly from normal, make atmospheric pressure an unfavorable factor.

Therefore, we should not talk about favorable environmental factors, but about unfavorable values ​​of factors. The nature and degree of influence on a living organism of one or another environmental factor depends on the quantitative value of this factor. The further the value of the factor under consideration is from the zone of its comfortable values, the more unfavorable the effect of the factor on the living organism.

5.1.2. Normal and extreme living conditions. Survival

Comfortable or close to them values ​​of human environmental factors take place, as a rule, in normal human life, in peacetime. They are often referred to as normal living conditions.

Normal life-giving conditions provide for the life support of the population for a normal life, life in peacetime. Almost every Russian lives in these conditions.

In the event of emergencies, people in the emergency zone may find themselves without shelter, water, food and medical care. In most cases, it is extremely difficult to solve the most important issues of life support for the affected population in these extreme conditions promptly and in the required volumes, because the supply system will be destroyed or its ability to fully meet all the needs of the victims will be insufficient.

In such cases, it turns out to be important to establish a priority life support for people, which at first provides for the satisfaction of only the physiological needs of a person, primarily in food.

In addition, in some emergency situations in the initial period of their occurrence, even the physiological needs of a person for energy cannot be satisfied. There are difficulties with housing, water, cooking, medical care, etc. Similar difficulties can also occur under other circumstances, when a person, regardless of the planned actions and the route of movement, geographical location, is cut off from the outside world and must rely only on himself. This is the extreme conditions of human life. For a person who is in extreme conditions, the desire to survive is natural, i.e. save your life.

The behavior of a person left to himself in extreme conditions, the purpose of which is to save his life, is survival.

Extreme conditions in which a person is fighting for survival are characterized by: the absence or lack of food (food); lack or shortage of drinking water; exposure to low or high temperatures on the human body.

Food provides the body's needs for energy and the functioning of all human organs and systems.

The composition of food should include proteins, fats, carbohydrates, vitamins.

Proteins form the basis of every living cell, every tissue of the body. Therefore, a continuous supply of protein is absolutely necessary for the growth and repair of tissues, as well as the formation of new cells. The most valuable proteins are meat, milk, eggs and vegetables, primarily potatoes and cabbage and some cereals - oatmeal, rice, buckwheat.

Fats and carbohydrates are the main sources of energy and determine mainly the calorie content of food. Animal fats are considered more complete than vegetable fats. The most useful fats contained in milk, cream, sour cream. Carbohydrates are especially rich in cereals, vegetables, fruits, a certain amount of carbohydrates is found in milk.

Vitamins are necessary for the proper growth and development of the body, for the normal functioning of the gastrointestinal tract, neuromuscular apparatus, vision, etc. The most important for the body is vitamin C, vitamins of group B, vitamins A, D, E.

In addition, the composition of food should include minerals (calcium, magnesium, phosphorus) necessary for the skeletal system, as well as cardiac and skeletal muscles. The need for them is fully covered if the food consists of a variety of products of animal and vegetable origin.

In the human body, processes of oxidation (combination with oxygen) of physical food substances (proteins, fats, carbohydrates) are continuously occurring, accompanied by the formation and release of heat. This heat is necessary for all life processes, it is spent on heating the released air, on maintaining body temperature, thermal energy ensures the activity of the muscular system. The more muscle movements a person makes, the more he consumes oxygen, and, consequently, the more he produces costs, but more food is needed to cover them.

The need for a certain amount of food is usually expressed in thermal units - calories. The minimum amount of food that is necessary to maintain the human body in a normal state is determined by its needs at rest. These are human physiological needs.

The World Health Organization has established that the physiological needs of a person for energy are about 1600 kcal per day. The real energy needs are much higher, depending on the intensity of labor, they exceed the indicated norm by 1.4-2.5 times.

Starvation is a state of the body in the complete absence or insufficiency of the intake of nutrients.

Distinguish between absolute, complete and incomplete starvation.

Absolute starvation is characterized by a complete lack of intake of nutrients - food and water.

Complete fasting is starvation when a person is deprived of all food, but is not limited in water consumption.

Partial starvation occurs when, with sufficient quantitative nutrition, a person does not receive some nutrients with food - vitamins, proteins, fats, carbohydrates, etc.

With complete starvation, the body is forced to switch to internal self-sufficiency, consuming fat reserves, muscle protein, etc. It is estimated that a person of average weight has energy reserves of approximately 160 thousand kcal, 40-45% of which he can spend on internal self-sufficiency without a direct threat to his existence. This is 65-70 thousand kcal. Thus, spending 1600 kcal per day, a person is able to live in conditions of complete immobility and lack of food for about 40 days, and taking into account the implementation of motor functions - about 30 days. Although there are cases when people did not eat for 40.50 and even 60 days and survived.

In the initial period of fasting, which usually lasts 2-4 days, there is a strong feeling of hunger, a person constantly thinks about food. Appetite rises sharply, sometimes there is a burning sensation, pain in the pancreas, nausea. Dizziness, headaches, stomach cramps are possible. When drinking water, salivation increases. In the first four days, a person's weight decreases by an average of one kilogram daily, and in areas with a hot climate - up to 1.5 kg. Then the daily losses decrease.

In the future, the feeling of hunger weakens. Appetite disappears, sometimes a person even experiences some cheerfulness. The tongue is often covered with a whitish coating, and the smell of acetone can be felt in the mouth. Salivation does not increase, even at the sight of food. There is poor sleep, prolonged headaches, irritability increases. A person falls into apathy, lethargy, drowsiness, weakens.

Hunger undermines the strength of a person from the inside and reduces the body's resistance to external factors. A hungry person freezes several times faster than a full one. He gets sick more often and endures the course of the disease more difficult. His mental activity weakens, his working capacity drops sharply.

Water. The lack of water leads to a decrease in body weight, a significant loss of strength, thickening of the blood and, as a result, an overstrain of the heart, which expends additional effort to push the thickened blood through the vessels. At the same time, the concentration of salts in the blood rises, which serves as a formidable signal that dehydration has begun. Dehydration of the body by 15% or more can lead to irreversible consequences, to death. If a person deprived of food can lose almost the entire supply of tissue, almost 50% of proteins, and only after that approach the dangerous line, then the loss of 15% of the fluid is fatal. Starvation can last several weeks, and a person deprived of water dies in a matter of days, and in a hot climate - even hours.

The need of the human body for water in favorable climatic conditions does not exceed 2.5-3 liters per day.

It is important to distinguish true water hunger from the apparent one. Very often, the feeling of thirst arises not due to an objective lack of water, but due to improperly organized water consumption. Therefore, it is not recommended to drink a lot of water in one gulp - this will not quench your thirst, but can lead to swelling, weakness. Sometimes it is enough to rinse your mouth with cold water.

With intense sweating, leading to leaching of salts from the body, it is advisable to drink slightly salted water - 0.5-1.0 g of salt per 1 liter of water.

Cold. According to statistics, from 10 to 15% of people who died in various extreme conditions became victims of hypothermia.

The wind plays a decisive role in human survival in low temperatures. At an actual air temperature of 3 0 С and a wind speed of 10 m/s, the total cooling caused by the combined effect of the actual air temperature and the wind is equivalent to the effect of a temperature of –20 0 С. And a wind of 18 m/s turns a frost of 45 0 С into a frost of 90 0 C in the absence of wind.

In areas devoid of natural shelters (forest, relief folds), low temperatures combined with strong winds can shorten human survival to several hours.

Long-term survival at sub-zero temperatures also depends largely on the condition of clothes and shoes, the quality of the built shelter, fuel and food supplies, and the moral and physical condition of a person.

Clothing is capable of protecting a person from the cold in extreme conditions only for a short time, yet sufficient for the construction of a shelter (even a snow one). The heat-shielding properties of clothing depend primarily on the type of fabric. Finely porous fabric retains heat best of all - the more microscopic air bubbles are enclosed between the fibers of the fabric, the closer they are to each other, the less such a fabric transmits heat from the inside and cold from the outside. There are a lot of air pores in woolen fabrics - the total volume of pores in them reaches 92%; and in smooth, linen - about 50%.

By the way, the heat-shielding properties of fur clothing are explained by the same effect of air pores. Each villus of fur is a small hollow cylinder with an air bubble "sealed" inside it. Hundreds of thousands of such elastic microcones make up a fur coat.

Recently, clothing made from synthetic materials and fillers such as synthetic winterizer, nitron, etc. has found wide application. Here, air capsules are enclosed in the thinnest shell of artificial fibers. Synthetic clothing is slightly inferior to fur in terms of warmth, but it is very light, does not impede movement, and is almost not felt on the body. It is not blown by the wind, snow does not stick to it, it gets wet a little.

The most optimal clothing option is multi-layered clothing from different fabrics - best of all from 4-5 layers.

Shoes play a very important role in winter emergencies, because 90% of all frostbite occurs on the lower extremities.

by all accessible ways we must strive to keep shoes, socks, footcloths dry. To do this, you can make shoe covers from improvised material, wrap your legs with a piece of loose fabric, etc.

Refuge. Clothing, no matter how warm it is, can protect a person from the cold only for hours, rarely for days. No clothing can protect a person from death if a warm shelter is not built in time.

Cloth tents, shelters from the wreckage of vehicles, wood, metal in the absence of a stove will not save you from the cold. After all, when building shelters from traditional materials, it is almost impossible to achieve hermetic sealing of seams and joints. The shelters are blown through by the wind. Warm air escapes through numerous cracks, therefore, in the absence of stoves, stoves and other highly efficient heating devices, the air temperature inside the shelter is almost always equal to the outside.

An excellent shelter in winter can be built from snow, and very quickly - in 1.5-2 hours. In a properly built snow shelter, the air temperature rises to minus 5-10 0 C only due to the heat emitted by a person at 30-40 degree frost outside. With the help of a candle, the temperature in the shelter can be raised from 0 to 4-5 0 C and above. Many polar explorers, having installed a couple of stoves inside, heated the air up to +30 0 C!

The main advantage of snow shelters is the ease of construction - they can be built by anyone who has never held a tool in his hands.

5.2. Major Human Factors Contributing to Survival

Will to live. With a short-term external threat, a person acts on a subconscious level, obeying the instinct of self-preservation. In extreme conditions, with long-term survival, the instinct of self-preservation is gradually lost, sooner or later a critical moment comes when exorbitant physical and mental stress, the seeming senselessness of further resistance suppress the will. A person is seized by passivity, indifference, he is no longer afraid of the possible tragic consequences of ill-conceived overnight stays, risky crossings. He does not believe in the possibility of salvation and therefore perishes without exhausting his reserves of strength to the end, without using food supplies. 90% of people who find themselves on life-saving equipment after a shipwreck die within three days from moral factors. More than once, rescuers removed dead people from boats or rafts found in the ocean in the presence of food and flasks of water.

Survival, based only on the biological laws of self-survival, is short-lived. It is characterized by rapidly developing mental disorders and hysterical reactions - a psychogenic damaging factor acts. The desire to survive must be conscious and purposeful. This is the will to live, when the desire to survive should be dictated not by instinct, but by conscious necessity. The will to live implies first of all actions. Inaction is inaction. One cannot passively expect help from the outside, one must take actions to protect oneself from adverse factors, to help others.

General physical training, hardening. The usefulness of general physical training for a person who finds himself in an extreme situation does not need to be proved. In an extreme situation, strength, and endurance, and hardenedness are needed. These physical properties in conditions of extreme preparation it is impossible to acquire. This takes months. Servicemen-rescuers acquire them during physical exercises, tactical and special training, as well as during individual lessons in certain sports in their free time.

Knowledge of self-rescue techniques. The basis of long-term survival is solid knowledge in the most knowledge - recipes for cooking dishes from caterpillars and tree bark.

A box of matches will not save a person from freezing if he does not know how to properly build a fire in winter or in the rain. Wrong rendered first health care only exacerbates the condition of the victim. It is tempting to have comprehensive knowledge of self-rescue in any climatic zone of the country, in any extreme situations. But this is associated with the assimilation of a large amount of information. Therefore, in practice, it may be sufficient to confine ourselves to the study of a specific climate zone and possible emergency situations. However, it is important to study in advance those self-rescue techniques that are suitable for any climatic zone, typical extreme situations: orienteering, determining the time, making fire in primitive ways, organizing a camp, preserving food, "extracting" water, first aid, overcoming water obstacles etc. We must remember the motto: "To know is to be able, to be able is to survive!".

Survival skills. Knowledge of survival techniques must be supported by survival skills. Survival skills are acquired by practice. Having, for example, a weapon, but not possessing the skills of hunting, one can die of hunger with an abundance of game. When mastering the skills of survival, one should not "scatter around", trying to immediately master the entire amount of information on a particular issue of interest. It is better to be able to do less, but better. It is not necessary to practically master the construction of all types of snow shelters (there are about 20 of them), it is enough to be able to build three or four shelters of various designs.

Proper organization of rescue operations. The survival of a group that finds itself in an extreme situation largely depends on the organization of rescue operations. It is unacceptable that each member of the group does only what he considers necessary for himself at a given time. Collective survival allows you to save the life of each member of the group, individual - leads to the death of everyone.

The work within the camp should be distributed by the head of the group in accordance with the strengths and capabilities of each. Physically strong, especially men, should be entrusted with the most labor-intensive work - arranging firewood, building shelters, etc. Weakened, women and children should be given work that is time-consuming, but does not require much physical effort - maintaining a fire, drying and repairing clothes, collecting food, etc. At the same time, the importance of each work, regardless of the labor costs invested in it, should be emphasized.

All work should, as far as possible, be carried out at a calm pace with an even expenditure of energy. Sudden overloads followed by a long rest, irregular work lead to a rapid exhaustion of forces, to the irrational expenditure of the body's energy reserves.

With the proper organization of work, the expenditure of forces of each member of the group will be approximately the same, which is extremely important with a ration, that is, an equal diet for everyone.

5.3. Survival in the natural environment

5.3.1. Fundamentals and tactics of survival in the natural environment

The basics of survival in the natural environment are solid knowledge in a wide variety of areas, from the basics of astronomy and medicine, to recipes for cooking from non-traditional "foods" that may be in the place of survival - tree bark, plant roots, frogs, insects, etc. d. It is necessary to be able to navigate without a compass, give distress signals, be able to build a shelter from bad weather, light a fire, provide yourself with water, protect yourself from wild animals and insects, etc.

Of great importance is the choice of tactics for survival in the natural environment.

In conditions of survival, three types of human behavior are possible, three tactics of survival - passive survival, active survival, a combination of passive and active survival.

passive survival tactics- this is the expectation of help from rescuers at the scene of an accident or in its immediate vicinity, the construction of housing facilities, the equipment of landing sites, the extraction of food, etc.

The tactics of passive waiting justifies itself in cases of accidents, forced landings of vehicles, the disappearance of which involves the organization of rescue operations to locate and rescue the victims. It is applied in situations where there is absolute certainty that the missing will be searched for and when it is known for certain that the rescue units know the approximate area of ​​​​the location of the victims.

Passive survival tactics are also chosen when among the victims there is a non-transportable patient or several seriously ill patients; when the group of victims is dominated by women, children and unprepared for action, poorly equipped people; under especially difficult climatic conditions, excluding the possibility of active movement.

Active Survival Tactics- this is an independent exit of accident victims or rescuers to the nearest settlement, to people. It can be used in cases where the hope of an ambulance is excluded; when it is possible to establish your location and there is confidence in reaching the nearest settlements. Active survival is also used in cases where there is a need to urgently leave the original place due to severe weather and other factors and start looking for an area convenient for passive survival. Active survival is also used in the event of evacuation of victims from the disaster area.

In some cases, combined, that is, including an active and passive form of survival tactics, is possible. In this case, a long-term camp (bivouac) is organized by the joint efforts of the victims, after which a route group is created from among the most prepared. The purpose of the route group is to reach the nearest settlement as soon as possible and, with the help of local search and rescue services, organize the evacuation of the rest of the group.

5.3.2. Location orientation. Orientation by sun and stars

A. Determining the sides of the horizon during the day

If you do not have a compass, you can determine the approximate direction of the north from the sun (and knowing where the north is - all the other sides of the horizon). Below is a method by which you can, at any time when the sun is shining brightly enough, determine the sides of the horizon from the shadow of the pole (Fig. 5.1).

Find a straight pole one meter long and do the following:

1. Drive the pole into the ground on a flat area free from vegetation, on which the shadow is clearly visible. The pole does not have to be vertical. Tilting it to get the best shadow (in size and direction) does not affect the accuracy of this method.

2. Mark the end of the shadow with a small peg, stick, stone, branch, your own finger, a hole in the snow, or any other means. Wait until the end of the shadow has moved a few centimeters. With a pole length of one meter, you need to wait 10-15 minutes.

3. Mark the end of the shadow again.

4. Draw a straight line from the first mark to the second mark and extend it approximately 30 cm beyond the second mark.

5. Stand so that the toe of the left foot is at the first mark, and the toe of the right foot is at the end of the drawn line.

6. You are now facing north. Define the other sides of the horizon. To mark directions on the ground (for orienting others), draw a line crossing the first in the form of a cross (+), and mark the sides of the horizon. The basic rule when determining the sides of the horizon. If you are not yet sure whether to put your left foot or right foot on the first mark (see paragraph 5), remember the basic rule that distinguishes east from west.

The sun always rises on the east and sets on the west (but rarely exactly east and exactly west). The shadow moves in the opposite direction. Therefore, in any place on the globe, the first mark of the shadow will always be in the western direction, and the second - in the East.

For an approximate determination of the north, you can use an ordinary clock (Fig. 5.2).

In the northern temperate zone, clocks are set so that the hour hand points to the sun. The north-south line lies between the hour hand and the number 12. This refers to standard time. If the hour hand is set one hour ahead, then the north-south line passes between the hour hand and the number 1. In summer, when the clock hands are moved another hour forward, the number 2 should be taken into account instead of the number 1. If you are in doubt which side line is north, remember that the sun in the Northern Hemisphere is in the eastern part of the sky before noon, and in the western part of the afternoon. The clock can also be used to determine the sides of the horizon in the southern temperate zone, but in a slightly different way than in the northern zone. Here the number 12 should be directed to the sun, and then N-S line will pass in the middle between the number 12 and the hour hand. When moving the hour hand one hour ahead, the N-S line lies between the hour hand and the number 1 or 2. In both hemispheres, the temperate zones are between 23 and 66 ° north or south latitude. In cloudy weather, put a stick to the center of the clock and hold it so that the shadow from it falls clockwise. In the middle between the shadow and the number 12, the direction to the north will pass.

Rice. 5.2. Determination of the direction to the north with the help of a clock.

You can also navigate by the constellation Cassiopeia. This constellation of five bright stars is shaped like a tilted M (or W when low). The North Star is right in the center, almost in a straight line from the central star of this constellation, about the same distance from it. as well as from the Big Dipper. Cassiopeia also rotates slowly around the North Star and is always almost opposite the Big Dipper. This position of this constellation is of great help for orientation in the case when Ursa Major is low and may not be visible due to vegetation or high local objects.

In the Southern Hemisphere, you can determine the direction to the south and from here all other directions can be determined by the constellation of the Southern Cross. This group of four bright stars is shaped like a cross tilted to one side. The two stars that form the long axis or rod of the cross are called "pointers". From the base of the cross, mentally extend a distance five times the length of the cross itself and find an imaginary point; it will serve as the direction to the south (Fig. 5.4.). From this point look straight at the horizon and choose a landmark.

Plants can also help in determining the cardinal points. Tree bark, individual stones, rocks, walls of old wooden buildings are usually thicker covered with moss and lichen on the north side (Fig. 5.5). The bark of trees on the north side is rougher and darker than on the south side. In wet weather, a wet dark stripe forms on the trees (this is especially noticeable in pines). On the northern side of the trunk, it persists longer and rises higher. In birches on the south side of the trunk, the bark is usually lighter and more elastic. In pine, the secondary (brown, cracked) bark on the north side rises higher along the trunk.

In spring, the grass cover is more developed and dense on the northern outskirts of the glades warmed by the sun, in the hot period of summer, on the contrary, on the southern, shaded ones. The anthill has a flatter side facing south.

In spring, on the southern slopes, the snow seems to “bristle”, forming southward ledges (thorns), separated by depressions. The border of the forest along the southern slopes rises higher than along the northern ones.

Rice. 5.5. Determination of the direction to the north by the anthill, annual rings and moss on the stones.

The most accurate are astronomical methods for determining the cardinal points. Therefore, they should be used in the first place. Use all others only as a last resort - in conditions of poor visibility, inclement weather.

5.3.3. Definition of time

The method of determining the north direction by shadow (Fig. 5.6) can be used to determine the approximate time of day. This is done in the following way:

1. Move the pole to the point where the east-west and north-south lines intersect and place it vertically on the ground. Anywhere the globe the western part of the line corresponds to 6.00 hours, and East End -18.00.

2. Now the N-S line becomes the noon line. The shadow of the pole is like the hour hand on a sundial, and with its help you can tell the time. Depending on your location and time of year, the shadow can move either clockwise or counterclockwise, but this does not interfere with the determination of time.

3. A sundial is not a clock in the usual sense. The duration of the "hour" varies throughout the year, but it is generally accepted that 6.00 always corresponds to sunrise, and 18.00 to sunset. However, a sundial is quite suitable for determining the time in the absence of a real clock or for setting the clock correctly.

Determining the time of day is very important for scheduling a meeting, conducting a planned concerted action by individuals or groups, determining the remaining length of the day before dark, and so on. 12:00 solar time will always actually be noon, however, other hour hand readings compared to normal time vary slightly depending on location and date.

4. The method of determining the sides of the horizon from the clock can give erroneous readings, especially at low latitudes, which can lead to "circling". To avoid this, set your watch to the sun, and then determine the sides of the horizon from it. This method eliminates 10- the minute wait required to determine the sides of the horizon from the movement of the shadow, and in this time you can get as many readings as needed to avoid "circling".

Rice. 5.6. Determining the time of day from the shadow.

Determining the sides of the horizon in this modified way will correspond to determining the north direction from the shadow of the pole. The degree of accuracy of both methods is the same.

Basic concepts of survival

Human life has always been fraught with danger. It is no coincidence that our distant ancestors, taking their first steps along the path of evolution, learned to use the stone not only as a tool of labor, but also as a weapon.

The struggle for existence forced people by hook or by crook to cling to life, to adapt to any adversity, no matter how difficult they may be, to boldly go towards dangers. The desire to realize the seemingly impossible, permeating the entire history of mankind, helps to understand the incredible efforts made by people in various parts of the world in order to adapt to harsh natural conditions. Man has always had the ability to adapt to the natural and artificial environment - from primitive hunters who went out to the beast with a stone ax in their hands, to space travelers of the second half of our century, who have been in a state of weightlessness for a long time, mobilizing all their physical and mental capabilities. Survival is active, expedient actions aimed at preserving life, health and performance in an autonomous existence. It is for people whose lives are constantly fraught with dangers that preliminary preparation, both physical and psychological, is very important. Rescuers, military personnel of many branches of the armed forces, tourists who go on long routes, many scientists and researchers must first go through a complete adaptation process, as a result of which the body gradually acquires resistance to certain environmental factors that was absent before and, thus, gets the opportunity to "live in conditions previously incompatible with life”, which means complete adaptation to the conditions of the polar cold, hot deserts or lack of oxygen at mountain heights, fresh water in the salty sea. People who have undergone full adaptation have a chance not only to save life itself, but also to solve problems that were previously unsolvable.

The adaptation process is very complex and multi-stage. At its first stage, the stage of adaptation to any new factor, the body is close to the maximum of its capabilities, but it does not solve the problem that has arisen completely. However, after some time, if a person (or animal) does not die, and the factor requiring adaptation continues to act, the possibilities of the living system increase - the extreme, or urgent, stage of the process is replaced by the stage of effective and stable adaptation. This transformation is the key link in the whole process, and its consequences are often striking. Extreme conditions - an event (or a sequence of events) in which a person, through his own preparedness, the use of equipment and gear, as well as the involvement of additional, pre-prepared resources, has the opportunity to prevent an emergency, and, if necessary, help himself and others after an emergency. An extreme situation is an event outside of personal human experience, when a person is forced to act (or remain inactive) in the complete absence of equipment, equipment and initial training. (Basic information about ways to overcome the ES is not formalizable in principle, based on the very definition of an extreme situation). Most people and animals placed in extreme situations from which there is no way out do not die, but acquire one or another degree of adaptation to them and save their lives until better times. Such stressful situations - long periods of hunger, cold, natural disasters, interspecific and intraspecific conflicts - are always widely represented in the natural habitat of animals. The same scheme operates in the human social environment. During a relatively short period of its history, humanity went through periods of slavery, serfdom, world wars, but did not degrade, demonstrating high efficiency of adaptation to extreme situations. Of course, the price of such adaptation is unreasonably high, but these indisputable facts inevitably lead to the conclusion that the body must have sufficiently effective specialized mechanisms that limit the stress response and prevent stress damage and, most importantly, allow one to save life and health. In general, all this corresponds to a well-known everyday observation - people who have gone through severe life tests acquire a certain resistance to damaging environmental factors, i.e. resilient in any extreme situation. Imagine that a miracle happened, and today's man suddenly found himself in the primitive conditions of the existence of mankind. Making his way along the damp walls of the cave, to the sonorous chatter of his own teeth, our hero recalls the fire with unexpected joy. What about chopping wood? Well, okay, you can break the branches. He habitually hits himself in the pocket. Oh, horror, no matches! At first, our time traveler does not realize the full depth of the catastrophe that has befallen him. But in a minute it is covered with cold sweat. He has no idea how to make a fire without matches! Feverish attempts to make fire by rubbing wooden sticks against each other, cutting sparks lead to nothing - kindling stubbornly does not want to flare up. Further, with inexorable consistency, it turns out that a representative of our time cannot hunt without a gun, fish without lines and hooks, cannot build even the most primitive shelter, has no idea how to protect his mortal body from hundreds of dangers lurking from all sides. Hunted looking around, he rushes through the ancient forest, occasionally attacking the berries, which do not saturate at all. Our contemporary is doomed. He has to survive in conditions of autonomous existence. Autonomous existence is the activity of a person (a group of people) without outside help. The only chance to prolong their existence is to seek help from the local natives. It's nothing you can do! And then he meets the real masters of that era: the genius of getting food, the genius of making fire. With great effort, starting from the very basics, the unlucky traveler comprehends the science of "survival", with difficulty pulling himself up to the level of development of primitive man. There is nothing exaggerated in this fantasy. Even astronauts, before taking their place in the spacecraft, walk hundreds of kilometers along the paths of survival - forest wilds, hot sands of deserts. A modern person, and even more so a professional rescuer, regardless of the planned actions and the route of movement in terrestrial and extraterrestrial space, timing and geographical location, must be ready to act in an emergency, without communication with the outside world, when you can rely only on yourself. For a person who finds himself in an extreme situation due to unforeseen circumstances, such as a plane crash, a shipwreck, military personnel, as well as lost tourists, survival is mainly a psychological issue, and the most important factor in this case is the desire to survive. Regardless of whether a person is left alone or as part of a group, emotional factors may appear in him - experiences due to fear, despair, loneliness and boredom. In addition to these mental factors, trauma, pain, fatigue, hunger, and thirst also influence the will to survive. How long will a person in trouble have to stay in conditions of autonomous existence in extreme conditions? It depends on a number of reasons that determine the duration of autonomous existence.

The reasons for the duration of autonomous existence:

Remoteness of the area of ​​search and rescue operations from settlements;

Violation or complete absence of radio communications and other types of communications;

Unfavorable geographical, climatic and meteorological conditions of the area of ​​search and rescue operations;

Availability of food stocks (or lack thereof);

The presence in the area of ​​search and rescue operations of additional search and rescue forces and means.

Goals and tasks of rescuers on survival issues

The purpose of training rescuers for survival is to develop in them stable skills for actions in various conditions of the situation, to develop high moral and business qualities, self-confidence, reliability of rescue equipment and equipment, and the effectiveness of search and rescue support.

The basis of survival is solid knowledge in various fields, from astronomy and medicine to the recipe for cooking dishes from caterpillars and tree bark.

Survival techniques in each climatic and geographical region are different. What can and should be done in the taiga is unacceptable in the desert and vice versa.

A person must know how to navigate without a compass, give a distress signal, go to a settlement, get food with the help of gathering, hunting, fishing (including without a gun and the necessary gear), provide himself with water, be able to protect himself from natural disasters and much more. other.

The practical development of survival skills is extremely important. It is necessary not only to know how to behave in a given situation, but also to be able to do it. When the situation becomes threatening, it is too late to start learning. Before high-risk trips, it is necessary to conduct several emergency field exercises that are as close as possible to the real situation of future routes. It is necessary to calculate in advance theoretically and, if possible, check almost all possible emergencies.

Basic concepts of survival

Human life has always been fraught with danger. It is no coincidence that our distant ancestors, taking their first steps along the path of evolution, learned to use the stone not only as a tool of labor, but also as a weapon.

The struggle for existence forced people by hook or by crook to cling to life, to adapt to any adversity, no matter how difficult they may be, to boldly go towards dangers. The desire to realize the seemingly impossible, permeating the entire history of mankind, helps to understand the incredible efforts made by people in various parts of the world in order to adapt to harsh natural conditions. Man has always had the ability to adapt to the natural and artificial environment - from primitive hunters who went out to the beast with a stone ax in their hands, to space travelers of the second half of our century, who have been in a state of weightlessness for a long time, mobilizing all their physical and mental capabilities. Survival is active, expedient actions aimed at preserving life, health and performance in an autonomous existence. It is for people whose lives are constantly fraught with dangers that preliminary preparation, both physical and psychological, is very important. Rescuers, military personnel of many branches of the armed forces, tourists who go on long routes, many scientists and researchers must first go through a complete adaptation process, as a result of which the body gradually acquires resistance to certain environmental factors that was absent before and, thus, gets the opportunity to "live in conditions previously incompatible with life”, which means complete adaptation to the conditions of the polar cold, hot deserts or lack of oxygen at mountain heights, fresh water in the salty sea. People who have undergone full adaptation have a chance not only to save life itself, but also to solve problems that were previously unsolvable.

The adaptation process is very complex and multi-stage. At its first stage, the stage of adaptation to any new factor, the body is close to the maximum of its capabilities, but it does not solve the problem that has arisen completely. However, after some time, if a person (or animal) does not die, and the factor requiring adaptation continues to act, the possibilities of the living system increase - the extreme, or urgent, stage of the process is replaced by the stage of effective and stable adaptation. This transformation is the key link in the whole process, and its consequences are often striking. Extreme conditions - an event (or a sequence of events) in which a person, through his own preparedness, the use of equipment and gear, as well as the involvement of additional, pre-prepared resources, has the opportunity to prevent an emergency, and, if necessary, help himself and others after an emergency. An extreme situation is an event outside of personal human experience, when a person is forced to act (or remain inactive) in the complete absence of equipment, equipment and initial training. (Basic information about ways to overcome the ES is not formalizable in principle, based on the very definition of an extreme situation). Most people and animals placed in extreme situations from which there is no way out do not die, but acquire one or another degree of adaptation to them and save their lives until better times. Such stressful situations - long periods of hunger, cold, natural disasters, interspecific and intraspecific conflicts - are always widely represented in the natural habitat of animals. The same scheme operates in the human social environment. During a relatively short period of its history, humanity went through periods of slavery, serfdom, world wars, but did not degrade, demonstrating high efficiency of adaptation to extreme situations. Of course, the price of such adaptation is unreasonably high, but these indisputable facts inevitably lead to the conclusion that the body must have sufficiently effective specialized mechanisms that limit the stress response and prevent stress damage and, most importantly, allow one to save life and health. In general, all this corresponds to a well-known everyday observation - people who have gone through severe life tests acquire a certain resistance to damaging environmental factors, i.e. resilient in any extreme situation. Imagine that a miracle happened, and today's man suddenly found himself in the primitive conditions of the existence of mankind. Making his way along the damp walls of the cave, to the sonorous chatter of his own teeth, our hero recalls the fire with unexpected joy. What about chopping wood? Well, okay, you can break the branches. He habitually hits himself in the pocket. Oh, horror, no matches! At first, our time traveler does not realize the full depth of the catastrophe that has befallen him. But in a minute it is covered with cold sweat. He has no idea how to make a fire without matches! Feverish attempts to make fire by rubbing wooden sticks against each other, cutting sparks lead to nothing - kindling stubbornly does not want to flare up. Further, with inexorable consistency, it turns out that a representative of our time cannot hunt without a gun, fish without lines and hooks, cannot build even the most primitive shelter, has no idea how to protect his mortal body from hundreds of dangers lurking from all sides. Hunted looking around, he rushes through the ancient forest, occasionally attacking the berries, which do not saturate at all. Our contemporary is doomed. He has to survive in conditions of autonomous existence. Autonomous existence is the activity of a person (a group of people) without outside help. The only chance to prolong their existence is to seek help from the local natives. It's nothing you can do! And then he meets the real masters of that era: the genius of getting food, the genius of making fire. With great effort, starting from the very basics, the unlucky traveler comprehends the science of "survival", with difficulty pulling himself up to the level of development of primitive man. There is nothing exaggerated in this fantasy. Even astronauts, before taking their place in the spacecraft, walk hundreds of kilometers along the paths of survival - forest wilds, hot sands of deserts.

The reasons for the duration of autonomous existence:

Remoteness of the area of ​​search and rescue operations from settlements;

Violation or complete absence of radio communications and other types of communications;

Unfavorable geographical, climatic and meteorological conditions of the area of ​​search and rescue operations;

Availability of food stocks (or lack thereof);

The presence in the area of ​​search and rescue operations of additional search and rescue forces and means.

Goals and tasks of rescuers on survival issues

The purpose of training rescuers for survival is to develop in them stable skills for actions in various conditions of the situation, to develop high moral and business qualities, self-confidence, reliability of rescue equipment and equipment, and the effectiveness of search and rescue support.

The basis of survival is solid knowledge in various fields, from astronomy and medicine to the recipe for cooking dishes from caterpillars and tree bark.

Survival techniques in each climatic and geographical region are different. What can and should be done in the taiga is unacceptable in the desert and vice versa.

A person must know how to navigate without a compass, give a distress signal, go to a settlement, get food with the help of gathering, hunting, fishing (including without a gun and the necessary gear), provide himself with water, be able to protect himself from natural disasters and much more. other.

The practical development of survival skills is extremely important. It is necessary not only to know how to behave in a given situation, but also to be able to do it. When the situation becomes threatening, it is too late to start learning. Before high-risk trips, it is necessary to conduct several emergency field exercises that are as close as possible to the real situation of future routes. It is necessary to calculate in advance theoretically and, if possible, check almost all possible emergencies.

The main tasks of training rescuers for survival are to provide the necessary amount of theoretical knowledge and teach practical skills for:

Orientation on the ground in various physical and geographical conditions;

Providing self- and mutual assistance;

The construction of temporary shelters and the use of improvised means of protection from the effects of adverse environmental factors;

Obtaining food and water;

Use of means of communication and signaling for the withdrawal of additional forces and means to the area of ​​search and rescue operations;

Organization of crossings through water barriers and swamps;

Use of rescue boats;

Preparation of sites for landing helicopters;

Evacuation of victims from the disaster area.

Factors affecting survival

Training in survival actions is the main factor determining the favorable outcome of autonomous existence.

Risk factors

Climate. Adverse weather conditions: cold, heat, strong wind, rain, snow can reduce the limit of human survival many times over.

Thirst. Lack of water entails physical and mental suffering, general overheating of the body, rapidly developing heat and sunstroke, dehydration in the desert - inevitable death.

Hunger. Prolonged lack of food depresses a person morally, weakens physically, increases the impact on the body of adverse environmental factors.

Fear. Reduces the body's resistance to thirst, hunger, climatic factors, leads to the adoption of erroneous decisions, provokes panic, mental breakdowns.

Overwork. It appears as a result of strenuous physical activities, insufficient food supply, difficult climatic and geographical conditions, due to the lack of proper rest.

Natural disasters: hurricanes, tornadoes, snowstorms, sandstorms, fires, avalanches, mudflows, floods, thunderstorms.

Diseases. The greatest threat is posed by injuries, diseases associated with exposure to climatic conditions, and poisoning. But we should not forget that in an emergency, any neglected callus or microtrauma can lead to a tragic outcome.

Survival Factors

Will to live. With a short-term external threat, a person acts on a sensual level, obeying the instinct of self-preservation. Bounces off a falling tree, clings to stationary objects when falling. Another thing is long-term survival. Sooner or later, a critical moment comes when exorbitant physical, mental stress and the seeming senselessness of further resistance suppress the will. A person is seized by passivity, indifference. He is no longer afraid of the possible tragic consequences of ill-conceived overnight stays, risky crossings. He does not believe in the possibility of salvation and therefore perishes without exhausting his reserves of strength to the end.

Survival, based only on the biological laws of self-preservation, is short-lived. It is characterized by rapidly developing mental disorders and hysterical behavioral reactions. The desire to survive must be conscious and purposeful. You can call it the will to live. Any skill and knowledge becomes meaningless if a person resigns himself to fate. Long-term survival is ensured not by the spontaneous desire “I don’t want to die”, but by the goal set – “I must survive!”. The desire to survive is not an instinct, but a conscious necessity! Survival tool - various standard and homemade emergency kits and emergency supplies (for example, a survival knife). If you are going on a dangerous journey, you need to complete emergency kits in advance, based on the specific conditions of the trip, terrain, time of year, and the number of participants. All items must be tested in practice, repeatedly checked, duplicated if necessary. General physical preparation does not require comments. Psychological preparation consists of the sum of such concepts as the psychological balance of each member of the group, the psychological compatibility of the participants, the similarity of the group, the real idea of ​​the conditions of the future route, training trips that are close in terms of loads and climatic and geographical conditions to the real upcoming ones (or better twice exceeding them). Of no small importance is the correct organization of rescue work in a group, a clear distribution of duties in marching and emergency modes. Everyone should know what to do in the event of a threat of an emergency.

Naturally, the above list is far from exhausting all the factors that ensure long-term survival. Once in an emergency, first of all, it is necessary to decide what tactics should be followed - active (independent exit to people) or passive (waiting for help). With passive survival, when there is absolute certainty that the missing person or group is being sought, that the rescuers know their whereabouts, and if there is a non-transportable victim among you, you should immediately start building a capital camp, installing emergency signals around the camp, providing food on the spot.

Life support. Assessing the situation and making an informed decision

How to behave in extreme cases? Let's start with the basics and remember the key word for this situation "SURVIVAL":

S - assess the situation, recognize dangers, look for ways out of a hopeless situation.

U - excessive haste harms, but make decisions quickly.

R - remember where you are, determine your location.

V - conquer fear and panic, constantly control yourself, be persistent, but if necessary - obey.

I - improvise, be creative.

V - cherish the means of existence, recognize the limits of your capabilities.

A - act like a local, know how to evaluate people.

L - learn to do everything yourself, be independent and independent.

A group of people. First of all, it is necessary to choose an elder, a person who knows and is able to take all the necessary measures aimed at survival. If your group takes the following tips into account, then the chances of being rescued and returning home will increase significantly. Should:

Decisions are made only by the senior of the group, regardless of the situation;

Follow the orders of the senior group only;

To develop a sense of mutual assistance in the group.

All this will help to organize the activities of the group in such a way as to best ensure survival.

First of all, it is necessary to assess the current situation, which in turn consists of an assessment of the factors affecting survival.

The health status of group members, physical and mental condition;

The impact of the external environment (air temperature and the state of atmospheric conditions in general, terrain, vegetation, the presence and proximity of water sources, etc.).

Availability of emergency supplies of food, water and emergency equipment.

Provide self- and mutual assistance (if necessary) and draw up an action plan based on specific conditions, which should include:

Carrying out orientation on the ground and determining your location;

Organization of a temporary camp. Choosing a suitable place for building a shelter, taking into account the relief, vegetation, water sources, etc. Determination of the place of cooking, food storage, placement of a latrine, location of signal fires;

Provision of communication and signaling, preparation of radio equipment, operation and maintenance of them;

Distribution of responsibilities among group members;

Establishment of duty, tasks of duty officers and determination of the order of duty;

Preparation of visual signaling means;

As a result, an optimal mode of behavior in the current situation should be developed.

Help from local residents.

In most areas where a person or group of people injured in a disaster may be, there are always local residents. If you find yourself in a civilized country, the locals will always come to your aid and do everything necessary to get you home as soon as possible.

To enlist the support of local residents, be guided by the following:

It is better if the locals make contact first;

Deal on all matters with a recognized leader or leader; - Show friendliness, courtesy and patience. Don't show that you are afraid;

Treat them like human beings;

Respect their local customs and habits;

Respect the personal property of local residents; treat women with special respect;

Learn from the locals how to hunt and get food and water. Heed their advice regarding dangers;

Avoid physical contact with them, but in a way that is imperceptible to them;

Leave a good impression of yourself. Other people after you may need the same help.

When conducting RPS, rescuers often have to perform tasks far from populated areas, spend several days in the “field conditions”, and face various extreme situations, which imposes additional requirements on their ability to work in these conditions. Solid knowledge in various fields, the ability to use them in any conditions are the basis of survival. Going to the RPS, rescuers must, along with tools and protective equipment, have the following set of necessary items that can be useful in any climatic and geographical zone: a signal mirror, with which you can send a distress signal at a distance of 30-40 km; hunting matches, a candle or tablets of dry fuel for making a fire or heating a shelter; whistle for signaling; a large knife (machete) in a sheath, which can be used as a knife, ax, shovel, spear; a compass, a piece of thick foil and polyethylene, fishing equipment, signal cartridges, an emergency kit of medicines, a supply of water and food.

Signaling

Rescuers must know and be able to put into practice special signals. Rescuers can use fire smoke during the day and bright lights at night to indicate their location. If you throw rubber, pieces of insulation, oil rags into a fire, black smoke will be emitted, which is clearly visible in cloudy weather. To get white smoke, which is clearly visible in clear weather, green leaves, fresh grass, and damp moss should be thrown into the fire.

To give a signal from the ground to an air vehicle (aircraft), a special signal mirror can be used (Fig. 1). It is necessary to keep it at a distance of 25-30 cm from the face and look through the sighting hole at the plane; turning the mirror, match the light spot with the sighting hole. In the absence of a signal mirror, objects with shiny surfaces can be used. For sighting, you need to make a hole in the center of the object. The light beam must be sent along the entire horizon line, even in cases where the noise of the aircraft engine is not heard.

Rice. 1 Special signal mirror.

At night, the light of a hand-held electric flashlight, a torch, a fire can be used for signaling.

A fire built on a raft is one of the distress signals.

Good means of signaling are brightly colored objects and a special coloring powder (fluorescein, uranine), which are scattered on snow, earth, water, and ice when an aircraft (helicopter) approaches.

In some cases, sound signals (shout, shot, knock), signal rockets, smoke bombs can be used.

One of the latest developments in target designation is a small rubber balloon with a nylon shell, covered with four luminous colors, under which a light bulb flashes at night; the light from it is clearly visible at a distance of 4-5 km. Before launch, the balloon is filled with helium from a small capsule and held at a height of 90 m by a nylon cable. The mass of the kit is 1.5 kg.

In order to facilitate the search, it is advisable to use the International code table of air signals "Ground - Air" (Fig. 2). Its signs can be laid out with the help of improvised means (equipment, clothing, stones, trees), directly by people who must lie down on the ground, snow, ice, trampled on the snow.

Along with the ability to give signals, rescuers must be able to work and live in the field, taking into account meteorological (weather) factors. Monitoring the state and forecasting of the weather is carried out by special meteorological services. Weather information is transmitted by means of communication, in special reports, is applied to maps using conventional signs.

In the absence of information about the weather, rescuers must be able to determine and predict it according to local characteristics. To obtain reliable information, it is advisable to make a weather forecast simultaneously for several of them.

The blue spots over the forest weaken and soon completely disappear.

The weather imposes certain requirements on the organization of a bivouac, temporary housing, life and rest during multi-day RPS. With this in mind, rescuers organize a bivouac. It should be located in avalanche-safe and rock-fall-safe areas, close to a source of drinking water, have a supply of deadwood or firewood. It is impossible to arrange a bivouac in the dried up beds of mountain rivers, near the shallows, in dense shrubs, coniferous thickets, near dry, hollow, rotten trees, in thickets of flowering rhododendron. After removing stones, branches, debris from the site and leveling it, rescuers can proceed with setting up the tent. (Fig. 3)

Tents differ in design features, capacity, material. Despite this, they are all designed to protect a person from cold, rain, wind, dampness, and insects.

The procedure for setting up the tent is as follows:

Expand the tent;

Stretch and secure the bottom;

Install the racks and tighten the guys;

Fasten the exit and tighten the roof braces;

Eliminate creases on the roof by tightening (loosening) the braces;

Dig a ditch around the tent with a width and depth of 8-10 cm to drain water in case of rain.

Under the bottom of the tent, you can put dry leaves, grass, ferns, reeds, moss. When setting up a tent on snow (ice), empty backpacks, ropes, windbreakers, blankets, and foam rubber should be placed on the floor.

The pegs are hammered at an angle of 45° to the ground to a depth of 20-25 cm. Trees, stones, ledges can be used to secure the tent. The back wall of the tent must be placed in the direction of the prevailing winds.

In the absence of a tent, you can spend the night under a piece of tarpaulin, polyethylene, or equip a hut from improvised materials (branches, logs, spruce branches, leaves, reeds). It is installed on a flat and dry place, in a clearing or the edge of a forest.

In winter, the campsite should be cleared of snow and ice.

Fig.3 Options for setting up tents.

In snowy winter conditions, rescuers must be able to arrange shelters in the snow. The simplest of them is a hole dug around a tree, the size of which depends on the number of people. From above, the pit must be closed with branches, dense cloth, covered with snow for better thermal insulation. You can build a snow cave, a snow dugout, a snow trench. When entering a snow shelter, you should clean your clothes from snow and dirt, take a shovel or knife with you, which can be used to make ventilation holes and a passage in case of snow collapse.

For cooking, heating, drying clothes, signaling, rescuers use fires of the following types: "hut", "well" ("log house"), "taiga", "nodya", "fireplace", "Polynesian", "star", " pyramid". "Shalash" is convenient for making tea quickly and lighting the camp. This fire is very "gluttonous", it burns hot. “Well” (“log house”) is kindled, if you need to cook food in a large bowl, dry wet clothes. In the "well" the fuel burns out more slowly than in the "hut"; a lot of coals are formed, which create a high temperature. On the "taiga" you can cook food at the same time in several pots. On one thick log (approximately 20 cm thick), several thinner dry logs are placed, which approach each other at an angle of 30 °. necessarily on the leeward side. Fuel burns for a long time. Near such a fire you can stay for the night. "Nodya" is good for cooking food, heating during the night, drying clothes and shoes. Two dry logs up to 3 m long are placed close to each other, flammable fuel (thin dry twigs, birch bark) is ignited in the gap between them, after which a third dry log of the same length and 20-25 cm thick is placed on top. To prevent the logs from rolling out, with flyers are driven into the ground on two sides of them. They will simultaneously serve as supports for the stick on which the bowlers are hung. The “nodya” flares up slowly, but it burns with an even flame for several hours. Any fire must be made only after careful preparation of the site: collection of dry grass and deadwood, making a deepening in the ground, fencing with stones the place where it will be bred. The fuel for the fire is dry forest, grass, reeds, shrubs. It has been noticed that burning spruce, pine, cedar, chestnut, larch give a lot of sparks. Oak, maple, elm, beech burn quietly. To quickly kindle a fire, kindling is needed (birch bark, small dry branches and firewood, a piece of rubber, paper, dry fuel). It is tightly packed with a “hut” or “well”. To make the kindling light up better, put a piece of candle in it or put dry alcohol. Thicker dry branches are laid around the kindling, then thick firewood. In wet weather or during rain, the fire must be covered with a tarpaulin, a backpack, a thick cloth. You can kindle a fire with matches, a lighter, sunlight and a magnifying glass, friction, flint, a shot. In the latter case, you need:

Open the cartridge and leave only gunpowder in it;

Lay dry cotton wool on top of the gunpowder;

Shoot at the ground, while observing safety measures;

The smoldering cotton wool will ensure the kindling of the fire.

To set up a fire in winter, it is necessary to clear the snow to the ground or build a deck of thick logs on the snow, otherwise the melted snow will extinguish the fire. To prevent a fire from causing a fire, it should not be made under low tree branches, near flammable objects, on the leeward side, relative to the bivouac, on peat bogs, near reeds and reeds, dry grass, moss, in spruce and pine undergrowth. In these places, the fire spreads at high speed and is difficult to extinguish. In order to prevent the spread of fire, the fire must be surrounded by a ditch or stones. The safe distance from the fire to the tent is 10m. To dry clothes, shoes, equipment near the fire, they should be hung on poles or ropes located on the leeward side at a sufficient distance from the fire. An obligatory rule is to extinguish the fire (with water, earth, snow) when leaving the bivouac. Successful fulfillment by rescuers of the tasks assigned to them is possible only if the body restores and maintains high mental and physical performance throughout the entire period of work. This is based on a balanced diet. It is important not only the correct ratio of proteins, fats and carbohydrates in food, but also the mandatory presence of vitamins and other biologically active substances in it. The rescuer's daily diet should include at least 1.5 g of protein per kilogram of body weight, almost the same 4 times more carbohydrates, as well as about 30-35 g of table salt, vitamins, water, etc.
