What are the main causes of fire deaths?

Clause. 1. Hypoxia.

Because combustion requires a large amount of oxygen, a lack of oxygen in the surroundings can lead to hypoxia.

Clause. 2. Carbon monoxide poisoning.

Oxygen is needed for combustion, and a large part of the gas is removed, which is carbon monoxide, and we all know that when the body inhales a large amount of carbon monoxide, it will cause poisoning and eventually lead to death.

Clause. 3. Burns.

When the fire reaches a certain level, the hot air and open flames will cause burns to our **, which can cause a series of complications.

The four main causes of death caused by fires are: lack of oxygen, inhalation of toxic gases, inhalation of hot gases, and burns. The first three causes are all related to the respiratory tract, which is "internal injury" caused by fire, and ** burns are "external injury".

Generally, the temperature of the flame is about 200-1000 degrees, and the temperature of the room can reach more than 400 degrees after 10-15 minutes of fire, and the human body will be burned in less than 1 second.

Burns and scalds caused by fire are a type of disease with high difficulty, long course and high mortality, and it is often combined with a variety of injuries, such as inhalation injuries and knock injuries. Because ** is the largest organ of the human body, when it is damaged by destructive injury, its protective effect on the body, immune function, regulating the body's body temperature and preventing excessive loss of body water will be lost. If the wound is not repaired in time, it will lead to infection, metabolic disorders and other problems.

Patients often lead to multi-organ failure and die from severe sepsis.

The main reason may be that the safety passage is blocked.

Towels do not block toxic gases.

1. Hypoxia. The smoke from the fire is sometimes hypoxic due to the consumption of burning oxygen.

2. Inhalation of toxic gases. Especially carbon monoxide.

3. Inhale hot air. When a fire is directly baked by a flame, it inhales hot gases at high temperatures, resulting in suffocation and death.

4. Burns. Various complications arise due to damage to a large area** due to flame or hot air currents.

and cause death.

There are four main types:

1) Toxic gases (especially carbon monoxide). In a fire, carbon monoxide is considered to be the most toxic gas. Although hydrocyanic acid and other toxic gases can also be detected in the deceased, these have little direct effect on the death.

2) Hypoxia. Because the combustion oxygen is consumed, the smoke in the fire is sometimes hypoxic. Inhalation of this smoke causes a lack of oxygen, which can sometimes lead to death.

3) Burns. Death due to fire or hot air damage to a large area** can cause various complications.

4) Inhale hot air. If it is directly baked by the flame in a fire, it will inhale hot gases with high temperatures, which will lead to tracheal inflammation and pulmonary edema, and suffocation.

Precautions in case of fire:

1. Be sure to remember to call the police in case of fire.

2. Life is the most important, don't delay the escape time because of looking for valuables.

3. When the building is **, you can't escape by ordinary elevator, because it is easy to lose power, or make the elevator car deformed by heating and stuck, so that the escape fails.

4. Do not walk upright when the smoke is full, otherwise it is easy to choke on smoke and poisoning.

5. If you find heat or smoke from the crack in the door, you can not open the door rashly, but try to find other channels, if you find that it is not hot, you should open it slowly, and use the door leaf as a cover on one side to prevent the smoke from falling down or the heat wave burning.

6. When escaping, every door and window should be closed to prevent fireworks from spreading along the passage.

7. If the escapee is on fire, he should quickly take off or tear off his clothes, or roll on the spot to extinguish the fire, but be careful not to roll too fast, and remember not to run with the fire in the wind. If there is a pool, river, pond, etc., jump into the water quickly to extinguish the fire on your body.

8. After escaping from the fire danger zone, the victim must stay in a safe area and do not re-enter the fire to avoid danger.

Fire refers to a catastrophic burning phenomenon that is out of control in time or in the space of the cherry blossoms. Among all kinds of disasters, fire is one of the main disasters that most frequently and universally threatens public safety and social development. As scary as it sounds, what are some of the causes of death in fires?

Among them, the first thing that comes to our mind may be hypoxia, because combustion requires a large amount of oxygen, and when the surrounding oxygen is insufficient, the guide mode will cause hypoxia;

The second reason is carbon monoxide poisoning, it is obvious that oxygen is needed during combustion and a large part of the gas will be eliminated at the same time, this gas is carbon monoxide, we all know that when the body inhales a large amount of carbon monoxide, it will be poisoned, and finally lead to death;

The third reason is burns, when the fire reaches a certain level, the hot air flow and open flames will cause burns to our **, which will cause a series of complications and death. The last reason is prolonged inhalation of hot air, which can lead to suffocation and death due to tracheitis, posture and pulmonary edema.
