First, obtain and improve respiratory conditions
Without air, people can only live for a few minutes; without water, people can live for about 7 days; without food, they have a record of 30-40 days. Therefore, air is the survival problem that must be solved first. People are surrounded by fireworks. When there is no air or little air, in order to survive, the main methods are as follows:
(a) Expand air sources and reduce oxygen consumption. Once people are buried in coma, they should not cry out loud enough to avoid excessive consumption of oxygen. When you feel suffocated, you can breathe in close to the gap to ensure the air source.
(b) Ensure breathing space and avoid gas poisoning. When people are surrounded by poisonous gas and fireworks, they try their best to protect a confined room to cut off the effects of poisonous gas and fireworks, and reduce or avoid poisoning of the human body. Generally speaking, each person has 1 cubic meter of free space and can breathe for 2 hours.
(3) Low posture, aggressiveness, and escape from an oxygen-deficient environment as soon as possible. In the pyrotechnics and high temperature environment, the oxygen content in the lower part is relatively high. In this case, using a low attitude forward, you can run out of a few smoke chambers or a section of toxic gas leak. The longer the helium time, the farther the toxic hypoxia area can be crossed.
Second, save water to find the basic needs of survival
Learn to endure thirst and drink a few times. When people are buried under water shortage conditions, if there is a small amount of water, they drink less water. In the absence of water, foods that are easy to consume water, such as fats and proteins, should be eaten even if they are rich in food, so as to reduce the demand for water.
Collect urine, waste water, rainwater, and expand the source of water. In the absence of water, urine can quench thirst. If it rains, it can also use plastic film to collect rainwater to expand the source of water.
Third, protect and find food, keep the minimum energy source
Food is a guarantee of the metabolism of human life. Individuals should be able to meet the needs of living for two days at least for foods that are stored in emergency, and families should have two or more weeks of storage.
The food should not be directly contaminated by nuclear, chemical, or warfare agents, and the equipment that has been used for warfare agents should not be used in the diet of domestic animals and poultry, and insects should not be allowed to bite the food.
When you are surrounded by the rubble of a collapsed building and can't escape, try to control the amount of food you take with you, extend your eating time, and wait for help.
Fourth, seek rescue, out of danger
(a) determine his position. When you are still able to move, first look for light. When tapping around, the wall with a crisp sound is the empty wall, and it is possible for sounds to be heard or safe roads to be excavated. After you initially determine your location, you can find your way to the most convenient direction.
(b) Send a distress signal. You should choose the direction closest to the outside world based on your environment. Throwing out small objects, waving handkerchiefs, hitting the surrounding walls, using small sticks to shake cloths, or using flashlights with ordered flashes of light, etc., caught the attention of rescue workers.
(3) Trying to escape the danger zone. Poisonous areas, contaminated areas, infected areas, and fire areas are all dangerous areas.
