This type of extinguisher is designed for specific types of fires and has particular characteristics.
How it works: CO2 extinguishers work by displacing oxygen around a fire, which suffocates the flames. The gas is also extremely cold when discharged, which helps to cool the burning material.
Suitable for: They are most effective on Class B fires (flammable liquids like petrol or oil) and fires involving electrical equipment.
Safety: CO2 is a non-conductive gas, making it safe to use on electrical fires.
Residue: A key advantage is that it leaves no residue, making it ideal for use on sensitive electronics and in offices.
Caution: Because it displaces oxygen, it should be used with caution in confined or poorly ventilated spaces to avoid the risk of asphyxiation.
