Why is smoke in a fire easy to kill?

Smoke in the fire quickly spreads, containing many types of seeds, vapors, toxic gases, inhaled bodies and oxygen deficiency, nervous system damage and death risks.

Most people die in a fire due to inhaling smoke, not burns. The smoke easily spreads, resulting in disorientation, making it more difficult for the victim to escape. The commonly used synthetic materials today make smoke more toxic because of the release of dangerous substances. In addition, lung and respiratory damage caused by inhalation of toxic gases sometimes occurs only after 24-36 hours of exposure, making the victim subjective and untreated.

According to the National Fire Protection Association, smoke in a fire is lethal because it contains the following ingredients:

1. Small particles are not burned, burned partially or completely small enough to pass through the filter of the respiratory system to the lungs.Some seeds are very toxic while others are irritating to the eyes and digestive system.
2. Vapor-like types poison the body if inhaled or absorbed through the skin.
3. The toxic gases that are most common are carbon monoxide (CO), which causes the body to lose oxygen, damage the nervous system, push the victim into a coma, lose consciousness or be worse than death.Only 0.1% CO in the air is life-threatening.In addition, hydrogen cyanide occurs when the resin is burned to block respiratory cells.Household items using vinyl materials if phosgene is generated;At low levels, it causes an itchy eye, a high level of sore throat that causes pneumonia, death.

In addition to toxic smoke, the fire reduces oxygen in the air by consuming oxygen or replacing it with other gases. Oxygen below the standard concentration of 21% leads to the following harms:

Heat is also a systemic respiratory threat. The air reaches a certain degree of heat enough to kill people with one breath.

In order to avoid the risk of death from smoke, in the event of a fire, quickly exit by crawling to the ground, covering a cloth or cloth with water on your mouth, nose and moving to fresh air Respiratory examination to promptly intervene. Watch for signs such as hoarseness, voice changes, shortness of breath, black phlegm because they warn serious problems. Victims of suffocation should be taken to a medical facility immediately.
