Code for fire protection requirements of escape windows in 2022

1, in principle, fragile glass is required, ordinary glass is fine, tempered glass can also be used, and firefighters can break it open with a percussion hammer. But laminated glass can't be used. Mark the window.

2. The fire escape window is for firefighters to enter. The net size of the window should not be less than 0.8m wide and 1m high. The distance under the window cannot be higher than1.2m.

3. The rescue window should correspond to the climbing place of the fire truck, and a fire zone should have at least two rescue windows.

Second, what is the fire escape window:

Fire escape window is a window for people trapped indoors to escape from danger when the stairs and walkways can't be used normally in case of fire. Fire escape window, also known as fire rescue window, is a window which is set on the external wall on one side of the fire climbing surface of high-rise building, and is easy for firefighters to quickly enter the main body of building fire control and identify.

Third, the necessity of opening the fire escape window:

Nowadays, many families and enterprises use fully enclosed anti-theft nets. Although this anti-theft effect is good, it also directly blocks the escape route.

In case of fire, the window is a necessary channel for trapped people to save themselves. If the corridor has been blocked by fire and there is no fire escape window, then the only escape route for trapped people indoors is blocked, which wastes the most precious self-help time. Because the anti-theft net is completely closed, it is difficult for firefighters to find the entrance, and even the water gun can't aim at the fire point. They can only enter the fire after cutting the anti-theft net, and it takes at least 3 minutes to cut the anti-theft net, which will greatly delay the time to control the fire and rescue the trapped people, and the consequences are worrying. If a fire escape window is set, the trapped people in the lower floor can escape by jumping off a building or climbing, while the trapped people in the upper floor can stand by the window and wait for the rescue of firefighters. On-site firefighters can also find the entrance smoothly through the fire escape window, control the fire in time and rescue the trapped people.

Therefore, the fire escape window is an "important" channel to ensure the escape of trapped people and the rescue of firefighters, and it is necessary to set up fire escape windows.
