In a 5 kg DCP cartridge type extinguisher .the co2 cartridge pressure becomes 7 kg/cm2.
Because mono ammonium phosphate itsself is a excellent fire retardant, that is very it is used in the DCP fire extinguisher.
Nytrogen gas
The expiry time of a DCP fire extinguisher is usually around seven years. After this, the powder should be replaced. Additionally, these extinguishers should be checked yearly to ensure all parts are present and that the seals are intact.
ABC is the acronym for an extinguisher certified for A, B, and C type fires. A is common fuels like wood, B is for flammable liquids, and C is for charged electrical fires. DCP stands for Dry Chemical Powder, which is inside the extinguisher and is the actual fire suppressant. Basically, DCP is a type of ABC Extinguisher. You can also get extinguishers for Type D (combustible metals), Type K (kitchen), and other specialized extinguishing agents (i.e. Halon). Or you can get a Type A extinguisher, AB, B, BC, ABC, and others even!
DCP fire extinguishers use dry chemical powder as the extinguishing agent, typically composed of monoammonium phosphate. This powder effectively interrupts the chemical reaction in the fire by smothering the flames and preventing re-ignition. DCP extinguishers are suitable for Class A, B, and C fires, making them versatile for various types of fires.
basically in DCP (dry chemical powder) fire extinguishers mono ammoniumphosphate is used. but some more chemicals compound are also used e.g. sodium bicarbonate, potassium bicarbonate, pottasium chloride etc.
Since petroleum is a flammable liquid, a Class B fire extinguisher would be used.

To extinguish a plastic material fire, use a Class A, B, or C fire extinguisher as appropriate. For small fires, you can also smother the flames by covering them with a fire blanket or using water to cool the material. Avoid using water on electrical or grease fires involving plastic materials.
Nitrogen is used in dry chemical powder (DCP) extinguishers as a propellant to expel the extinguishing agent effectively. It is an inert gas, which means it does not support combustion, making it safe for use in fire suppression. Additionally, nitrogen helps maintain the integrity of the dry chemical agent by preventing moisture absorption, ensuring it remains effective during storage.
tell me what kind of fire extingting ushers should not be used on ???
