In a 5 kg DCP cartridge type extinguisher .the co2 cartridge pressure becomes 7 kg/cm2.
A pure CO2 fire extinguisher is recharged by pouring in liquid C02. It usually takes a professional refilling company to determine the proper amount and to pour it in safely. Dry ice, crushed to get it into the extinguisher tank, can also be used.
Some fire extinguishers are not directly pressurized, but have an external pressurized cartridge (or system of multiple cartridges) that is activated when pressure is needed. Also, in portable fire extinguishers, there may be either a pressure cartridge or a manual pump for some kinds of extinguishers. Another obsolete method (the soda-acid extinguisher) included a cylinder of sodium bicarbonate solution with a bottle of sulfuric acid, none of which was pressurized. When you inverted the extinguisher or pressed a plunger to spill the acid into the bicarb, the resulting CO2 gas would pressurize the container and blow the bicarb/water/acid solution out through the hose aimed at the fire.
A type B extinguisher.
A burning box of wood or paper would require a type A extinguisher.
A typical restaurant would require at least one Type ABC fire extinguisher plus a Type K fire extinguisher near the kitchen (for grease and fryer fires).
BC type Dry powder extinguisher is the hydrocarbon extinguisher since it is used for extinguishing hydrocarbon fires.
A type A or C02
Yes. They are rated for the type of fire they can be used against, and the capacity of the extinguisher.
It will put out burning fluids.
Air craft is fitted with extinguisher bottle which is operated with press switch in cockpit . It fuses a cartridge electrically and opens the passage. On ground, fire is extinguished with the help of foam extinguisher(cash tender).
