ABC multipurpose dry chemical is the only dry chemical agent that provides Class A fire extinguishment. It is monoammonium phosphate based containing chemical additives, and produced by an exclusive chemical process. The resultant agent is free-flowing, water repellant, non-abrasive, and when used as a fire suppressing agent will produce no toxic effects. ABC dry chemical is yellow in color to differentiate it from the other dry chemical agents.
Moisture may combine with monoammonium phosphate based agents in post fire situations to produce mild corrosion. Because of this, prompt cleanup is recommended.
ABC Multipurpose dry chemical suppressing agent may be used to combat fires in ordinary combustible materials such as wood, cloth, paper, rubber, and many plastics (Class A) as well as fires in flammable liquids, gases and greases (Class B) and fires involving energized electrical equipment (Class C). ABC dry chemical is of particular value on combination fires (Class A and B together), and on Class A fires at temperatures which would freeze water. A typical application is the heavy equipment used in the logging industry.
ABC dry chemical agent is available in hand portable and wheeled extinguishers, large stationary units, mobile units and various fixed nozzle piped systems.
Monoammonium phosphate based extinguishants are unique among dry chemicals because of the “A” rating. ABC dry chemical is at least 4 to 5 times as effective as an equal weight of water on Class A fires. Various extinguishers will operate at temperatures as low as –65 °F and as high as 120 °F (–54 °C and 49 °C).
Never mix ABC dry chemical agent with bicarbonate based dry chemicals. A chemical reaction that is harmful to the extinguisher will take place
