Fire Extinguisher DCP

They consist of a shell made of sheet steel, pressurized with inert gas or with dehumidified air at about 15 bar, while inside there are powders consisting mainly of saline compounds, such as potassium bicarbonate or sodium bicarbonate (for class B and C fire) and ammonium sulphate and Monoammonium phosphate (for ABC classes of Fire)

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.
