Depends on what type it is and whether it is fixed or portable. There are many different kinds of fire extinguishers, some pressurized by air, nitrogen, carbon dioxide, among other things.

What else can I help you with?
What are fire extinguishers be used for?
FIRE extinguishers are used to put out fire.
What is the difference between dry chemical and hcfc 123 fire extinguisher?
Dry chemical fire extinguishers use a powder substance, such as sodium bicarbonate or monoammonium phosphate, to smother the fire and interrupt the chemical reaction. HCFC 123 fire extinguishers contain a clean agent called HFC-123, which is a halocarbon compound that extinguishes fires by removing heat and interrupting the chemical reaction. The main difference is in the extinguishing agent used, with dry chemical extinguishers being more versatile but leaving residue, while HCFC 123 extinguishers are cleaner and more suitable for sensitive equipment.
Is fire chemical or mechanical reaction?
Fire is a chemical reaction (oxydation).
What do fire extinguishers have inside?
A cold smoke. A really cold chemical.
Do fire extinguishers use oxygen?
No. Fire is a chemical reaction between oxygen and a flammable material. Adding extra oxygen speeds up the reaction, making the fire burn even hotter and making it easier for the fire to spread.
How does fire get extinguished through a dry chemical used in fire extinguishers?
It suffoctaes the fire by depriving the fire of air which it needs to burn.
What are the contents of a multipurpose fire extinguisher?
Multi-purpose fire extinguishers, like ABC, are typically dry chemical.
What do fire extinguishers remove from the fire triangle?
It depends upon what kind of extinguisher it is. Water, for example, removes the heat from a fire by turning into steam and by removing available air/oxygen from the flames. Other extinguishers remove the oxygen from the fire or change the chemical reaction to stop the fire from converting the fuel to a flammable substance with the available heat.
How does chemical reaction help fire?
Fire is the result of an oxidation reaction.
How is making a fire chemical reaction?
A chemical reaction is irreversible, while a physical change is reversible. Fire is a chemical reaction because you can't get back the products.
Multipurpose dry chemical extinguishers are effective on all classes except?
D and K fire
Is fire in a fireplace a physical or chemical property?
Fire is not a physical or chemical property. Fire is not a property. Fire is a chemical reaction where oxygen combines with some or all of the chemical components of the fuel, emitting light and heat.
