Carbon Dioxide Fire Extinguishers


A carbon dioxide fire extinguisher (CO2 extinguisher) displaces the oxygen around the fire using non-flammable carbon dioxide gas. It thus is effective at suppressing a fire quickly. 

This type of CO2 fire extinguisher in operation is colorless, odourless and is not electrically conductive, while also leaving no residue. The carbon dioxide is typically housed in aluminium or light alloy.

Unlike water and foam fire extinguishers, CO2 Carbon Dioxide fire extinguishers do not have a cooling effect.

They should not be used on Class A fires (flammable solids) as they may spread the fire. Instead, they are typically suitable for Class B (flammable liquids and gases) and Class C fires (energised electrical).
