Matters needing attention in case of fire:

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 the smoke will block your view.

When we saw the fire scene in movies and TV, everything was very clear. It was shot outside the smoking 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.
