How a DCP fire extinguisher works?

A DCP (Dry Chemical Powder) fire extinguisher works by releasing a fine powder, typically made of monoammonium phosphate, which smothers the fire and interrupts the chemical reaction of combustion. When the extinguisher is activated, the pressurized gas inside propels the powder out through the nozzle, effectively covering the flames. This type of extinguisher is effective on Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical) fires. Its rapid application helps to quickly extinguish the fire while preventing re-ignition.
