Depends of the type of fire extinguisher.
Common CO2-extinguishers are filled with with compressed CO2. Once released it cooles down the fire below it's burning- or ignition-temperature and replaces the Air. The lack of oxigens will then suffocate the fire.
No matter what type of extinguisher, it's always about cooling of suffocating the flame.

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 is the minimum total size of fire extinguishers that must be present for hot work?
20 lbs
Do fire extinguishers really expire?
Yes. This is why it is important to have them serviced regularly.
Does fire extinguisher contain hydrogen?
Not elemental hydrogen, no. That would not work in a fire extinguisher as hydrogen is highly flammable. Some fire extinguishers do use water, however, which is a hydrogen compound.
What is a class d extinguisher used for?
No, hence them being Class D fire extinguishers they are only used on combustible metal fires. there are different class d extinguishers as well for specific metal fires no one class d extinguisher on all metal fires mostly very specific
How do you get vintage fire extinguishers to work?
It depends on the type. If it's not readily apparent, you should probably just get a new one.
What is in fire extinguishers co2 hydrogen nitrogen or oxygen?
Usually CO2. Hydrogen and oxygen are fuels for fire. Nitrogen would work but is not usually used as it is too light.
Two things which work on the principle of biotech and chemtech?
Two things which work on the principle of biotech and chem tech is a galvanometer apparatus and fire extinguisher.
Is the osha fire extinguisher training required to be a firefighter?
You will need to become an expert in how fire extinguishers work. Not only in terms of using them, but you'll need to be able to train others in their use as well.
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.
How would you put out a petrol fire?
They have specially made foaming extinguishers for this sort of thing, perhaps suffocating it (if it is very small) may work as well.
Do class a fire extinguishers put out oxygen heat or fuel?
Class A fire extinguishers are designed to put out fires involving ordinary combustible materials such as wood, paper, and textiles. They work by cooling the burning material to remove heat, which is one of the three elements of the fire triangle (heat, fuel, and oxygen). While they do not directly remove oxygen or fuel, by extinguishing the heat, they effectively prevent the fire from continuing to burn.
