What kinds of fire extinguishers do you have?

1. fire type a fire, that is, the solid combustion of fire should be selected water, foam, ammonium phosphate dry powder, halogenated type fire extinguishersThe B class is 2. saves and molten liquid fire fire solids should use dry powder, foam, carbon dioxide, halon fire extinguisher (here it is worth noting that the chemical foam fire extinguishers cannot destroy B polar solvent soluble fire, because chemical foam and organic solvent by touch, foam will be absorbed. The bubble quickly disappeared quickly, so you can not play the role of fire. Alcohols, aldehydes and ketones, ethers and esters are polar solvents).3., fire C fire, that is, gas burning fire should choose dry powder, halogenated alkane and carbon dioxide type fire extinguisher4., the use of Halon, carbon dioxide and dry powder fire extinguishers should be used to extinguish the live fire5., fire extinguishing live fire and live fire should be selected by phosphoric acid salt powder and halon fire extinguisher6. of the class D fire metal burning fire, China's current situation, no fire extinguisher products stereotypes.
