High-rise fires
The spread is fast and the rescue is difficult
Once it happens
It may cause serious casualties and property damage
High-rise building fire
Why did the fire spread so quickly?
This stems from the formation of high-rise buildings
The "Chimney Effect"
The chimney effect
The "chimney effect" is a phenomenon in which flue gas and hot air flow upwards due to convection of air currents in a relatively enclosed vertical space. In the event of a fire, the smoke may spread vertically through stairwells, pipe shafts, glass curtain wall gaps and other parts, and if the fire containment in these places is not done well, the smoke is likely to spread to the entire building in a short period of time, threatening the safety of personnel.
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, 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
High-rise buildings generally have more indoor combustibles, and some high-rise residential buildings also set up combustible warehouses in violation of regulations, once a fire starts, the burning is fierce and easy to spread.
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 is infiltrated in 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.
Here's a reminder to everyone
Fire safety in high-rise residential communities is of paramount importance
Please be vigilant and prevent "burning"!
In the case of a fire accident in a high-rise building
If you want to successfully escape
A lot of the time you have to save yourself

There is an evacuation floor > 100m high!
The interior decoration materials of the roof, walls and ground of the refuge floor are all non-combustible materials, and the refuge floor is equipped with openable windows or independent mechanical smoke-proof facilities. If you are in a super high-rise building that is more than 100 meters away.
Running up, or down?
There was a fire downstairs
If there is smoke in the stairwell
Never blindly escape through the stairwell
There was a fire upstairs
I'm going to run downstairs
Exterior ignition
The fire point and the size of the fire should be judged at the first time
Select the appropriate escape route
What should I do if the exit is blocked by smoke and fire?
If the exit is blocked by smoke or fire and cannot be safely crossed, you should choose to close the door on the current floor instead of running up or down. Remember, close the door, seal the crack with a wet towel, and call 119 quickly to wait for help!
