DCP (Dry Chemical Powder) Gas Cartridge Type fire extinguishers are a type of portable firefighting equipment commonly used for combating fires involving combustible materials such as paper, wood, textiles, flammable liquids, and electrical equipment. The gas cartridge contains a propellant such as nitrogen under pressure. When the extinguisher is operated, the gas is released, pressurizing the container and forcing the dry chemical powder out through the nozzle.

DCP extinguishers are versatile and effective for combating different types of fires, including those involving flammable liquids, gases, and electrical equipment.
