1. Extinguishing Class D fires, that is, metal burning fires. As far as my country's current situation is concerned, there is no finalized fire extinguisher product.

Dry sand or cast iron foam can be used to extinguish fires in the case of domestic production of fire extinguishers and fire extinguishing agent beads. Class D fire: refers to metal fires. Such as potassium, sodium, magnesium, titanium, aluminum-magnesium alloys, etc.

2. Dry powder, foam, alkyl halides, and carbon dioxide type fire extinguishers should be used to fight Class B, that is, liquid fires and meltable solid material fires. When the organic solvent is touched, the foam will be absorbed quickly and the foam will disappear quickly, so that it can not play the role of extinguishing fire. Alcohol, aldehyde, ketone, ether, ester, etc. are all polar solvents). Class B fire: refers to liquid fire and meltable solid material fire. Such as gasoline, kerosene, crude oil, methanol, ethanol, asphalt, etc.
