How to prevent fire?
1, don't smoke near dangerous goods, don't throw cigarette butts, don't smoke when sleeping, and don't smoke when walking. It is best to use a slightly larger ashtray and put some water on it, because the surface temperature of cigarette butts reaches 200 ~ 300℃ and the center temperature reaches 700 ~ 800℃, which is enough to ignite solid substances such as cotton, linen and paper.

Don't put the lighted candle near the window. Put out all candles when you leave the room or sleep, and don't light candles to stay up late to prevent fire accidents.

3. Be careful of flammable materials. Such as gasoline, kerosene, alcohol, natural gas, aircraft thinner and charcoal lighter oil, improper use will lead to fire.

4. Don't forget to turn off the power switch when you go out, and eliminate electrical faults in time to prevent electrical equipment from being overloaded. When leakage occurs, professional maintenance personnel should be found in time for maintenance, and the use of electrical appliances should be checked frequently. Prevent fire caused by illegal operation and use of unqualified products.

5. It is forbidden to burn sundries and use open flames in violation of regulations. Without the consent of the relevant departments, you can't use open flames at will, at the same time, prevent mosquito-repellent incense from causing fires, keep the evacuation passage unblocked, and prohibit piling up sundries in the evacuation passage.

6. Install fire alarm equipment, and use heat insulation and flame retardant materials in corridors, stairs and other important places to find fires in time, eliminate fires, reduce losses, and prohibit unauthorized movement of fire fighting equipment.

Fire self-rescue:

In a fire, trapped people should have good psychological quality, keep calm, don't panic, don't act blindly, and choose the correct escape method. It must be noted that the temperature at the scene of the fire is amazing, and smoke will block your view. When we saw the fire scene in movies and TV, everything was clear. It was shot outside the smoke on the fire.

When you are at the scene of a fire, the visibility is very low. Even in the room where you live for a long time, you can't figure out the location of the windows and doors. In this case, it is even more important to keep calm and not panic.

If you are trapped in a fire, you should use all available conditions around you to escape. You can use fire elevators and indoor stairs to escape. Ordinary elevators must not be used, because ordinary elevators are easy to cut off power, have no smoke prevention effect, and are likely to be stuck in the air in case of fire. At the same time, you can also use the water pipe on the outer wall of the building to escape.

After the fire, there will be smoke coming out. Stop immediately in case of heavy smoke. Never try to get out of the fireworks and crawl low in the smoke. Due to the rising of hot air, there will be a lot of smoke floating from the upper floor, so there should be air below 30 cm from the ground, so try to crawl in the smoke and keep your head close to the ground as much as possible.

Escape in the smoke, if the human body is not properly protected, it is easy to inhale the smoke into the human body, leading to fainting or suffocation, and at the same time, the eyes will be unable to open due to the stimulation of the smoke, resulting in stinging. At this time, transparent plastic bags can be used, regardless of size. Large plastic bags can cover the whole head and provide enough air for escape.

If there is no big plastic bag, you can use a small plastic bag. Although it can't completely cover the head, it can also cover the nose and mouth and supply the air needed for escape. When using plastic bags, be sure to open them completely, but don't blow them open with your mouth, because the gas blown in is carbon dioxide, which is counterproductive.

If you hear an alarm at night, you should first touch the door with the back of your hand to see if the door is getting hot. If it is hot, you can't open the door, or smoke and fire will rush into the bedroom. If the door is not hot, the fire may not be big, and it is possible to escape from the room through normal channels. Be sure to close the door after leaving the room to prevent the fire from spreading.
