The city is full of high-rise buildings
Working and living in high-rise buildings has become the norm
But once a fire breaks out in a high-rise building
The danger is enormous
Fire hazard of high-rise buildings
1. There are many fire hazards
High-rise buildings, especially comprehensive high-rise buildings, have complex functions, many combustibles, lax fire safety management, many fire hazards, and high fire hazards. In particular, smoke and toxic gases are produced in fires, which pose a great threat to life safety.
2. The fire spreads quickly
In high-rise buildings, stairwells, pipe wells and other structures are like chimneys, and when a fire occurs, it is easy to form air convection, which makes the smoke and flames spread rapidly. If the fire containment is not done properly, the fire may spread to the entire building in a short period of time.
3. Difficulty in safe evacuation
Most high-rise buildings rely on stairs for safe evacuation, but due to the large number of floors and long vertical distance, the evacuation time to the ground or other safe places is relatively long, and once smoke jumps into the stairwell, it will seriously affect the evacuation.
4. It is difficult to save
High-rise buildings are tens of meters high, or even hundreds of meters, and it is quite difficult to extinguish from the outside once the indoor firefighting facilities cannot function normally.
In the case of a fire accident in a high-rise building
If you want to successfully escape
It's important to learn to help yourself
