CO2 Fire Extinguishers – A brief guide

Fire needs Heat, Oxygen and Fuel to burn. A CO2 Fire Extinguisher works by displacing the oxygen quickly.  CO2 Extinguishers are extremely high pressure vessels – they are pressurized to 55 bar. As a comparison, your average car tyre is inflated to 2.3 bar!  The high pressure is necessary to force the CO2 gas into the atmosphere in sufficient quantity and speed to displace the Oxygen and extinguish the fire.  Without the high pressure, it would be ineffective.

Pros:

CO2 extinguishers are clean; they leave no residue and so are ideal in environments where alternatives may not be appropriate, for example, food preparation areas and office environments.  They can be used on Class B flammable liquid fires and are safe on electrical related fires.

Cons:

Not as effective outdoors.  CO2 Extinguishers have no Class A fire rating. This is because the CO2 will have little cooling effect. For some class A fires, this may allow reignition where materials are smouldering or extremely hot.  CO2 extinguishers should never be used in confined spaces as there is a risk of asphyxiation.

CO2 Fire Extinguishers come in 2Kg and 5Kg units.  Ideally suited to Kitchens, Garages, Office environments and where there is a risk of electrical related fires.

Keep in Mind when using a CO2 Extinguisher:

Do NOT use in a confined space with poor ventilation due to the risk of being overcome by the CO2 gas.  When discharged, the CO2 will make a very loud sound.  This is normal but can be startling for the unsuspecting user.

All our CO2 extinguishers come with a bracket included, are CE Approved and Kitemarked to BSEN3.
