When the fire is small, you can escape quickly through the safe passage, but don't take the elevator, because the fire may short-circuit the wires in the whole building, and the consequences of being trapped in the elevator will be unimaginable. The best way is to take the stairs and escape quickly under the guidance of safety signs.
When the fire is big, you can't evacuate quickly through the safe passage. In most cases, there will be smoke billowing. If there is no way to escape indoors, lock the door as soon as possible, turn on the faucet, wet the clothes or quilts in the house and block the door to prevent the smoke from entering the house. According to previous fires, many people were choked to death by smoke. After blocking the door, open the window and ask the outside world for help with something bright. If it is night, you can turn on the flashlight or the flash of your mobile phone for help. When the floor is low, you can also tear the sheets into strips to condense the rope and use the rope to quickly escape downstairs.
When you are in a tall building and the fire is from bottom to top, never go downstairs against the fire. The safest way is to climb up the stairs to the roof as soon as possible. Then wait quietly for help. If you encounter a corridor or passage filled with smoke in the process of survival, wet your clothes, cover your nose and mouth and crawl forward. Because smoke is rising, people must lean on the ground.
Generally speaking, it takes a short time for a fire to go from a very small Mars to a raging fire. In your daily work, you should put 1~2 fire extinguishers at home or in your office. It is best to put out the fire with a fire extinguisher. Don't be strong if you can't let it out. You should escape as soon as possible. In the past, some cases were because individuals tried to put out the fire, but they didn't put it out in the end. Instead, they trapped themselves in the sea of fire.
