A carbon dioxide (CO 2) fire extinguisher is a portable, active fire protection device that works by expelling carbon dioxide onto a fire. It works by displacing the oxygen the fire relies upon to continue burning, and it is primarily used to extinguish fires in which the source of the fuel is a flammable liquid or gas. Carbon dioxide fire extinguishers are a very common …
According to How Stuff Works, fire extinguishers use carbon dioxide to displace the oxygen necessary for a fire to burn, extinguishing the blaze. Fires need oxygen, fuel, and heat to ignite, and removing any one of those three components can put out a fire. Carbon dioxide extinguishers work because carbon dioxide molecules are heavier than oxygen molecules.
CO2 fire extinguishers – everything you need to know
How CO2 fire extinguishers work: CO2 fire extinguishers discharge CO2 gas, also known as carbon dioxide. This is stored in the extinguisher as a liquid, and the gas is created under pressure when the handle of the extinguisher is squeezed. This causes the CO2 gas to emerge at great speed, which is why CO2 fire extinguishers are not recommended for chip pan fires – …

What is a carbon dioxide fire extinguisher?
Carbon dioxide fire extinguishers are a very common form of fire extinguisher and are used in situations where traditional water and foam fire extinguishers or dry chemical fire extinguishers are not suitable. A carbon dioxide fire extinguisher is a “clean extinguisher” and leaves no residue on the area it is applied.
Why are fire extinguishers not suitable for chemical fires?
These extinguishers are not suitable for chemical or electrical fires since the liquid can conduct electricity and cause flammable agents to spread. Other extinguishers coat the fuel, forming a barrier between the flammable material and the oxygen in the surrounding air.
Where should a carbon dioxide fire extinguisher not be installed?
Carbon Dioxide fire extinguishers should not be installed in locations directly exposed to the sunlight or radiated heat. As they contain a pressure relief device they could be accidently discharged at temperatures exceeding 50 Degrees Celsius.
What type of fire extinguisher is used for Class E fires?
