What caused an explosion at a firecracker factory in Guanghan, Sichuan?

The cause of the explosion was that the nitrocellulose in the chemical raw material factory was affected by high temperature weather. When the temperature reached a certain temperature, the nitrocellulose began to burn, resulting in a large area of ??burning, and eventually caused the firecracker factory to explode.

The firecracker factory also contains a large amount of explosives and many chemical raw materials. These raw materials are very dangerous. When encountering volcanic conditions, large-scale explosions will occur. Therefore, firecracker factories must take all safety measures to prevent fire. I think firecracker factories should ban all fires directly, so that chemical raw materials and explosives will not explode. Most of the people who work in firecracker factories are men. Some people may not be able to control themselves, so they secretly take out a cigarette and hide in a corner to take a few puffs quietly when others are not paying attention. However, sometimes the cigarette butts are not completely extinguished and are blown by the wind, blowing the raw material room and explosives, causing ignition, causing the warehouse to catch fire, and then a large-scale explosion occurs. The power of the explosion in the firecracker factory is very scary, because there are a lot of explosives stored in the firecracker factory to supply production. Once an explosion occurs, it will threaten places several kilometers away from Fangyan. It is like a small atomic bomb. The destructive power after the explosion is very strong, which will take many lives and destroy many people's homes.

It is very important for firecracker factories to take precautions. The firecracker factory must have smooth air and cannot reproduce chemical raw materials and gunpowder at high temperatures. Because these raw materials will spontaneously ignite under the influence of high temperatures, they must be stored in a low temperature environment and in a dry environment, because once these pigments come into contact with moisture, they will deteriorate and lose their original properties. , some unexpected situations may occur during production. For example, during the production process, the manufactured firecrackers are sold to those who need them, but others may not be able to set them off when they take them, or the firecrackers may explode intermittently. These are all is the problem. Firecracker factories must not only deal with the problem of fire and explosion prevention, but also deal with the problem of raw material deterioration.
