1, sudden and unpredictable, makes it difficult to escape.

Building collapse is influenced by building structure, building quality, natural conditions and other factors. The collapse of buildings (structures) may happen at any time, the precursors of accidents are not obvious, and the time allowed for people to escape is very short. When people realize this, collapse accidents often have serious consequences.

2. It is easy to cause secondary disasters.

Sudden building collapse accidents may lead to the destruction of gas, power supply and other facilities in the building, leading to the occurrence of fires.

3. Rescue is very difficult

Due to the large number of trapped people and limited equipment, the effectiveness of rescue operations is bound to weaken, and post-disaster rescue is often a long-term continuous operation.

Matters needing attention in self-rescue when buildings collapse.

1. Move your body carefully, because the surrounding building debris may fall on yourself. Be extra careful and calm at this time.

2. The collapse of the house will spread the dust into the surrounding air. In order to avoid suffocation caused by inhaling dust, you should cover your mouth and nose with a towel or your own clothes or even your hands.

3. If you find steel pipes, ceramic pipes, gas pipes and other items that are easy to knock, you should ring these items with hard objects around you, so that rescuers can find you more easily.

In order to prevent the house from collapsing again, you need to build a relatively safe living space for yourself, and support the buildings that may collapse with solid objects around you, so that your space can be expanded.

When you find that you can't get out of danger, don't rush to call for help. Shouting loudly can easily lead to lack of oxygen and consume a lot of physical strength. You can wait for someone to pass by before shouting.
