Types of fire extinguishersWhat kinds of fire extinguishers are available? What are the differences in weight and material quality and what are their respective advantages and disadvantages?
Because our province's natural conditions, in our province common portable fire extinguishers only three: portable dry powder fire extinguishers, portable carbon dioxide fire extinguishers and portable halogen type fire extinguisher, the halogen type fire extinguisher for environmental protection effect, is not recommended. At present, most of the use of in hotels, restaurants, theaters, hospitals, schools and other public places is ammonium phosphate dry powder fire extinguisher (commonly known as the "ABC fire extinguisher") and carbon dioxide extinguishers, used in oil and gas filling stations and other places of the fire extinguisher is sodium bicarbonate (commonly known as "BC fire extinguisher") and carbon dioxide extinguishers.
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. The current fire extinguisher abroad class D mainly include powder fire extinguishers and fire extinguishing graphite metal special dry powder fire extinguishers. Has not yet finalized production of fire extinguishers and fire extinguishing agent can be used under the condition of dry beads sand or iron foam in China.

1. dry powder fire extinguishers. There are two kinds of extinguishing agents, namely sodium bicarbonate and ammonium phosphate extinguishing agent2. carbon dioxide fire extinguisher3. foam type extinguisher4. water type fire extinguisher5.
