Building collapse accident is a kind of disaster caused by man-made, meteorological, geological, terrorist, criminal, engineering quality and other factors. The consequences of building collapse accidents are very serious, which easily cause heavy casualties and property losses, and bring adverse effects to society.
Main characteristics of collapse accident
1. The emergency is strong, and it is difficult for people to escape. Affected by natural or human factors, building collapse accidents may occur at any time, and the precursor of the accident is not obvious, and the time for people to escape is very short. This kind of suddenness makes people unable to escape in time, which easily causes a large number of casualties.
2. The damage of facilities is easy to cause secondary disasters. Sudden building collapse accidents may cause the destruction of gas, power supply and other facilities inside the building, and lead to the occurrence of fire, especially the collapse of chemical plants and other structures. It is very easy to form a chain reaction, leading to the leakage of toxic gas (liquid) and explosion and combustion accidents.
