Sodium chloride
Burning Inside was created in 1995.
Burning Inside ended in 2007.
The gas becomes a liquid inside the extinguisher. When the extinguisher is operated, the liquid changes back to a gas when released.
Nytrogen gas
Burning from the Inside was created in 1983-07.
The gas typically present inside an incandescent light bulb is nitrogen or a mixture of nitrogen and argon. This gas helps prevent the tungsten filament from burning up by reducing the rate of evaporation.
Combustion occur and emission
In a 5 kg DCP cartridge type extinguisher .the co2 cartridge pressure becomes 7 kg/cm2.
An extinguisher rated for Class A, B and C fires would ordinarily be filled with a dry chemical (such as baking soda), and pressurized with a gas.
A cream fire extinguisher typically contains a mixture of water and foam concentrate, which is designed to combat Class A (solid combustibles) and Class B (flammable liquids) fires. The foam helps to smother the flames by forming a barrier that cuts off the fire's oxygen supply while also cooling the burning materials. The extinguisher is pressurized with air or nitrogen to allow for effective dispersal of the foam when activated. It is important to use a cream extinguisher only on appropriate fire classes, as it is not suitable for electrical or cooking oil fires.
valve releases stufff inside. puts out fire.
I have read it some where that the inside pressure of Co2 in fire extinguisher is 55 to 58 kg/cm2 at 21 deg C. However the pressure varies as per the ambient temperature.
