In the event of a fire involving such materials, it is first necessary to determine the properties of the burning material, then select an appropriate extinguishing agent for putting out the fire of that type of material, and carry out the extinguishing process correctly. http://www.dxkeu.cn/uploads/191011/1-191011141933H1.jpg (1) When fighting fires involving flammable and oxidizing gases, it is necessary to first close the pipeline valves, cool the containers and pipelines with water, and extinguish the flames using dry powder or sand. (2) To extinguish fires involving flammable and combustible liquids, use foam, dry powder, or carbon dioxide to put out the flames; at the same time, cool the area around the containers with water to prevent them from expanding and exploding. However, fires involving acids, ethers, and other flammable liquids that are soluble in water should be extinguished using alcohol-resistant foam. (3) To extinguish fires involving flammable and combustible solids, foam, dry powder, sand, carbon dioxide, or fogged water can be used. (4) To extinguish fires involving self-igniting materials, water, dry powder, sand, and carbon dioxide can be used. (5) To extinguish fires involving materials that burn when exposed to water, dry powder or dry sand can be used. (6) To extinguish fires involving oxidizers, dry powder, water, and carbon dioxide can be used. To learn more, please comment and follow
