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.

How does a fire extinguisher stop a combustion reaction?
A fire extinguisher stops a combustion reaction by removing one or more of the essential components of fire: heat, fuel, or oxygen. Different types of extinguishers work through various mechanisms; for example, water extinguishers cool the fire by absorbing heat, while foam extinguishers smother the flames, cutting off the oxygen supply. Dry chemical extinguishers interrupt the chemical reaction itself, effectively disrupting the combustion process. By targeting these elements, fire extinguishers effectively halt the fire's ability to sustain itself.
What are fire extinguishers be used for?
FIRE extinguishers are used to put out fire.
What are chemical fire extinguishers design to do?
Chemical fire extinguishers are designed to suppress or extinguish fires by using various chemical agents that interrupt the combustion process. They can be effective against different types of fires, depending on their specific chemical composition, which may include dry chemicals, foam, or wet agents. These extinguishers work by cooling the flames, suffocating the fire, or chemically disrupting the reaction that sustains combustion. Proper selection and use of the appropriate type of chemical extinguisher are crucial for effective fire control.
Which chemical is used in DCP fire extinguisher?
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.
What is the difference between dry chemical and hcfc 123 fire extinguisher?
The difference between a dry chemical and a hcfc 123 fire extinguisher is the material used to extinguish. Dy chemical fire extinguishers typically contain a fine white powder composed mainly of monoammonium phosphate. This powder extinguishes the fire but creates a lot of smoke and is highly corrosive. Hcfc fire extinguishers use Halon instead. Halon is a liquefied, compressed gas that cuts off the combustion reaction while it is happening. Halon has very few risks and very little is needed to extinguish fires.
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.
In general what are dry chemical fire extinguishers on?
Dry chemical fire extinguishers are primarily used to combat Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical) fires. They contain a dry chemical powder, such as monoammonium phosphate or sodium bicarbonate, which works by interrupting the chemical reaction of the fire. These extinguishers are versatile and effective in a variety of environments, making them a common choice for both residential and commercial use. However, they are not suitable for Class D (flammable metals) or Class K (cooking oils and fats) fires.
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.
