If the clothes on your body cause fire due to static electricity or careless smoking, you should take them off or tear them off quickly, or roll them up on the spot to put out the fire, but be careful not to roll them up too fast. Never run in burning clothes. If there is water, it can be quickly doused with water, but when the human body is burned by fire, it cannot be doused with water to prevent infection.

When a building fire is found, you should avoid panic and running around, calmly explore the fire location, determine the wind direction, and leave the upwind fire area quickly before the fire spreads. In case of fire, if the corridor is closed by fireworks, the doors and indoor ventilation holes should be closed immediately to prevent smoke from entering. Then block your nose and mouth with a wet towel to prevent inhalation of hot smoke and toxic gases, and wet your upward clothes to avoid scalding yourself. If there is only smoke in the corridor and there is no fire, you can put a large transparent plastic bag on your head to prevent smoke from irritating your eyes and inhaling into the respiratory tract. Smoke can escape from the fireworks area in a low posture.

General building fire protection design is divided into fire protection zone and smoke protection zone, and smoke protection zone is divided according to fire protection zone. Each fire zone must ensure that at least two entrances and exits lead to the adjacent fire zone or outdoor space, and can be extended to the area directly connected with the outdoor space if conditions permit. When you escape from the window, try to choose a place with open space outside. Don't rush to places where there are few people. I think it will be easier to run out because it is not crowded, but there may be no fire escape. There is something in architectural planning called fire climbing noodles.

Because the smoke produced at the fire site has the characteristics of high temperature, high toxicity, low oxygen content and high carbon monoxide content, it is easy for people to burn the respiratory system or poison the nerve center after inhalation. Therefore, when evacuating, cover your nose and mouth with a wet towel or handkerchief (but the thickness of the towel and handkerchief should not exceed six layers). Note: Don't evacuate with the wind, but quickly escape to the windward to avoid fireworks. Due to the excessive accumulation of smoke in the upper space, once a fire breaks out, it will spread rapidly upward and slowly horizontally. Don't walk upright when you escape, bend over or crawl, but don't crawl in case of liquefied petroleum gas or city gas fire.
