What is a dry chemical fire extinguisher?

Category: Fire Safety


Dry Chemical Extinguishers are fire extinguishers that have the ability to fight A, B, & C class fires. The key ingredient to this type of extinguisher is monoammonium phosphate. It is a non-conductive, corrosive agent, with a pale yellow color, that can effectively smother a fire by separating the oxygen from the fuel. Since dry chemical fire extinguishers utilize a corrosive element, they should be used as a last resort to extinguish electrical equipment. This type of extinguisher needs to be recharged after every use.
