What are the consequences of inhaling too much smoke in a fire?

Smoke inhalation from fire can be fatal and can also lead to loss of inhalation.

The leading cause of death from smoke is carbon monoxide poisoning. In air with carbon monoxide concentrations, a person can lose consciousness after two or three breaths, and 13 minutes of breath can lead to death. The amount of carbon monoxide in the flue gas produced by the combustion of commonly used building materials is as high.

In addition, the smoke from the fire contains a lot of carbon dioxide. In addition, there are some materials, such as polyvinyl chloride, nylon, wool, silk and other fibers can produce highly toxic gases when burned, which is a greater threat to people.

At the same time, smoke and gases in the fire can also lead to inhalation loss. Inhalation injury refers to the inhalation of some chemical components in hot air, vapors, smoke, harmful gases, and volatile chemicals, which can cause damage to the respiratory tract and lung parenchyma, as well as systemic chemical poisoning caused by the inhalation of toxic gases and substances.

Mild inhalation injuries are mostly confined to the mouth, nose and pharynx, and clinically visible sputum containing charcoal particles, redness, swelling of the mouth, sometimes blisters, and slight pain and dryness in the larynx. Moderate inhalation injuries predominantly affect the pharynx, larynx, and trachea, and are often accompanied by hoarseness and redness and edema of the upper respiratory tract.

Severe inhalation injury often injures the bronchioles, bronchioles, and alveoli, resulting in airway mucosal detachment, pulmonary edema, atelectasis, and severe dyspnea.

Inhalation injury can occur. Later reports include hypoxemia and carbon monoxide poisoning.

It mainly affects respiratory function. In addition to airway injury, pulmonary edema can occur quickly, and in severe cases, respiratory failure may occur.

Key points for self-rescue in case of fire:

1. The bathroom is a refuge.

In the event of a fire, if there is no way out, evacuate from the restroom. Because the humidity and temperature of the bathroom are high, you can use water to splash on the door and the floor to cool down.

2. If the room is outside the room and the fire is large, the door can be sealed with towels, quilts, etc., and water can be continuously poured to cool it to prevent the invasion of external flames and smoke.

3. Cover your mouth with a wet towel and crawl forward.

During the evacuation process, the mouth and nose should be covered with a wet towel or handkerchief to prevent inhalation of toxic gases. Because too much smoke gathers in the upper space during the fire, when escaping, do not walk upright, but bend over or crawl forward, but in the case of a liquefied petroleum gas or city gas fire, you should not use the creeping forward method.

4. You can't escape by ordinary elevator.

It is easy to cut off the power after the high-rise building, and at this time, there is a possibility of getting stuck in the ordinary elevator, which makes the evacuation invalid, but is in a more dangerous situation, and the personnel will be choked by the smoke and poisonous gas in the elevator at any time.

5. Don't jump off the building as a last resort.

If a multi-storey building is on fire and the smoke from the staircase is particularly violent, you can use ropes, fire hoses, or torn sheets to connect them, tie one end to a secure door or window, and then slide down the rope.

Hello, how to clear the smoke when inhaling in a fire, as follows.

1. If the fireworks are severe, you should go to the hospital immediately to avoid the delay of the disease and endanger your life.

2. If it is not very serious, move to a place with fresh air in time, drink some water first, wash your hands and face, and keep your breathing smooth.

3. You can take drugs to clear the lungs and moisten the lungs according to the doctor's instructions to ensure that the body can be used as soon as possible.

4. Eat more lung-clearing and detoxifying foods in your diet, such as fungus, duck blood, red beans, mung bean soup, etc., and you can also eat some fruits.

Satisfactory adoption.
