Saves a class B as liquid fire and melted solid material should be chosen type dry powder, foam, halogenated, carbon dioxide fire extinguisher (here it is important to note that chemical foam extinguisher fire cannot destroy the class B soluble solvent polarity, because chemical foam and organic solvent by touch, foam will quickly be absorbed, make bubble disappear very quickly, so you can't play the role of fire extinguishing. Alcohols, aldehydes, ketones, ethers, esters and other belong to a polar solvent). Class B fire: refers to a liquid fire and a molten solid material fire.
