Dry Powder Fire Extinguisher

This is a powder based agent that extinguishes by separating the four parts of the fire tetrahedron. It prevents the chemical reaction involving heat, fuel, and oxygen and halts the production of fire sustaining "free-radicals", thus extinguishing the fire.Monoammonium phosphate, also known as "tri-class", "multipurpose" or "ABC" dry chemical, used on class A, B, and C fires. It receives its class A rating from the agent's ability to melt and flow at 177 °C (350 °F) to smother the fire. More corrosive than other dry chemical agents.
