According to statistics, more than 80% people who died in the fire were suffocated by smoke. Fire products contain a lot of toxic components, such as carbon monoxide, carbon dioxide, hydrogen cyanide, sulfur dioxide, nitrogen dioxide and so on. These gases are harmful to human body to varying degrees. One of the most poisonous gases is carbon monoxide.

Although carbon dioxide is non-toxic, when it reaches a certain concentration, it will stimulate people's respiratory center, lead to shortness of breath, increase smoke inhalation, and also cause headaches, unconsciousness and other symptoms.

When the fire spreads, cover your nose and mouth with clothes, lower your body posture, take a shallow breath, and evacuate to the safety exit quickly and orderly. Try to avoid shouting and prevent toxic smoke from entering the respiratory tract.
