CO2 fire extinguishers are used on electrical fires. However, they are also effective on Class B fires, which are fires starting from flammable liquids. CO2 extinguishers can also be known as carbon dioxide extinguishers.
CO2 fire extinguishers have a black-coloured label stating ‘CO2’. It should also have a sign above or next to the extinguisher that states ‘CO2 Extinguisher’. A CO2 extinguisher can also be differentiated due to its distinctive black horn on the nozzle.
CO2 extinguishers come in foam sizes:
CO2 extinguishers disperse carbon dioxide. It’s stored in the extinguisher as liquid, and the gas is created under pressure when the extinguisher handle is squeezed. It works by dispersing the oxygen surrounding a fire and replacing it with carbon dioxide.
These extinguishers don’t have a cooling effect on the fire, so aren’t recommended for fires igniting from flammable solids.
These extinguishers are recommended as the standard for any building where there’s a risk of an electrical fire. Nearly all business premises present this risk, especially offices, schools and hospitals where there’s usually a large amount of electrical equipment on-site.
Often, a CO2 extinguisher is paired with a foam fire extinguisher in these kinds of environments, as this covers the majority of fire risks.
