| 器材选择 Equipment selection 1.扑救A类火灾即固体燃烧的火灾应选用水型、泡沫、磷酸铵盐干粉、卤代烷型灭火器。A类火灾：指固体物质火灾。这种物质往往具有有机物性质，一般在燃烧时能产生灼热的余烬。如木材、棉、毛、麻、纸张火灾等。 1. fire fighting type a solid burning fire should choose water type, foam, ammonium phosphate dry powder and halogenated alkane fire extinguisher. Class A fire: refers to solid material fire. This kind of material often has the organic property, generally can produce the burning ember when burning. Such as wood, cotton, wool, hemp, paper fire, etc. 2.扑救B类即液体火灾和可熔化的固体物质火灾应选用干粉、泡沫、卤代烷、二氧化碳型灭火器（这里值得注意的是，化学泡沫灭火器不能灭B类极性溶性溶剂火灾，因为化学泡沫与有机溶剂按触，泡沫会迅速被吸收,使泡沫很快消失,这样就不能起到灭火的作用.醇、醛、酮、醚、酯等都属于极性溶剂）。 B类火灾：指液体火灾和可熔化的固体物质火灾。如汽油、煤油、原油、甲醇、乙醇、沥青等。 2. fire fighting B, i.e. liquid fire and melted solid material fire, should use dry powder, foam, halogenated alkane and carbon dioxide extinguishers. Here it is worth noting that chemical foam extinguishers can not extinguish B type polar solvent fire. Because chemical foam and organic solvents are touched, the foam will be absorbed quickly, so that the foam will soon disappear. Loss, so it can not play the role of fire extinguishing. Alcohol, aldehyde, ketone, ether, ester and so on are polar solvents. Class B fire: refers to liquid fire and meltable solid fire. Such as gasoline, kerosene, crude oil, methanol, ethanol, asphalt and so on. 3.扑救C类火灾即气体燃烧的火灾应选用干粉、卤代烷、二氧化碳型灭火器。C类火灾：指气体火灾。如煤汽、天燃气、甲烷、乙烷等。 3. Dry powder, halogenated alkanes and carbon dioxide fire extinguishers should be used to extinguish class C fires, i.e. gas-burning fires. Class C fire: refers to gas fire. Such as coal gas, natural gas, methane, ethane, etc. |
