Fire self-help

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 we were at the scene of the fire, the visibility was very low. Even in the room where you lived for a long time, we couldn't figure out the location of the windows and doors. In this case, it is even more important to remain calm and not to 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.
