Dear experts: Can anhydride-based chemicals be extinguished using a dry powder fire extinguisher?
It should be possible. Dry powder fire extinguishers consist of three main types of components: First, those based on sodium bicarbonate, which are primarily used for extinguishing fires involving flammable liquids, gases, and electrical equipment. Second, those based on ammonium phosphate, which are mainly used for extinguishing fires involving flammable solids, liquids, gases, and electrical equipment. Third, those based on substances such as sodium chloride and potassium chloride, which are used primarily for extinguishing fires involving light metals! Generally, the dry powder fire extinguishers we use nowadays are mostly of type 2, and they can be fully used to extinguish acids and anhydrides!
