The open fire in Changsha China Telecom Building has been put out. What are the factors causing the fire?

The main cause of the fire is the fire of the external wall insulation material.

A large number of thermal insulation materials will be used in the construction of high-rise buildings, which is also to better improve people's living and office comfort. However, after the fire, these thermal insulation materials have also become combustion improvers. In high-rise buildings, the fire develops much faster than ordinary buildings. After a long period of wind, rain, sun and rain, many decorative layers of the external wall will crack or even burn, resulting in the exposure of thermal insulation materials. Once it comes into contact with a fire source, it will quickly trigger a fire, endanger its own life and cause huge economic losses.

The open flame of Changsha China Telecom Building has been put out.

On September 16, 2022, the command center of Changsha Fire Rescue Detachment received an alarm, and a fire broke out in China Telecom Building, East Second Ring Road, Furong District. Upon learning the situation, immediately dispatched 17 fire station, 36 fire engines and 280 commanders to the scene for disposal, and dispatched the detachment full-time headquarters. After arriving at the scene, after several hours of rescue, the fire was finally controlled. There are no casualties at present, but it has caused huge economic losses.

What are the factors causing the fire? The main reason for this bill of lading is that the external wall insulation material can make the building warm in winter and cool in summer, and it is composed of different materials. However, once a fire happens, it will also lead to an increase in the fire area, which will seriously affect the evacuation and fire rescue. According to related experiments, when the indoor fire spreads outward through the window, the polystyrene foam insulation material will burn completely in a short time, and the external insulation system adjacent to the fire floor will also burn, which may form a three-dimensional combustion of the building facade. So the loss caused by this fire is also great. I hope everyone can master some knowledge of fire safety in their lives, and flee the scene as soon as possible when a fire breaks out to ensure their own life safety.
