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.
The gas becomes a liquid inside the extinguisher. When the extinguisher is operated, the liquid changes back to a gas when released.

In a 5 kg DCP cartridge type extinguisher .the co2 cartridge pressure becomes 7 kg/cm2.
A red and cream fire extinguisher is typically classified as a foam extinguisher, designed for use on Class A and Class B fires. It is effective against fires involving solid combustibles like wood and paper, as well as flammable liquids such as petrol and paint. The cream color indicates its suitability for these types of fires, making it an essential tool for various environments, including commercial and industrial settings. Always check the label for specific usage guidelines.
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.
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.
Well, you CAN- depending on the type of fire.
