| 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盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门。如汽油、煤油、原油、甲醇、乙醇、沥青等。 To extinguish B, that is, liquid fire and melted solid substance fire, dry powder, foam, halogenated alkane and carbon dioxide type fire extinguishers should be chosen. It is worth noticing 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 disappear quickly. 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 |
