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.
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.
Extended data
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.
