DCP Fire Extinguisher
A DCP fire extinguisher (Dry Chemical Powder) is a type of fire extinguisher that uses a dry chemical powder as an extinguishing agent. This powder is typically a mixture of monoammonium phosphate and ammonium sulfate. When the powder is released from the extinguisher, it creates a cloud of fine powder that smothers the fire, cutting off the oxygen supply and preventing the fire from spreading.
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire. Pressure is generated by gas cartridges stored inside the cylinder. Its force will last for 45 seconds and can reach 3–4.5 metres (10–15 ft).
This fire extinguisher is diversely utilized because it is capable of extinguishing many classes of fire.
