A Carbon Dioxide (CO2) Fire Extinguisher is typically used for Class B (flammable liquids and gases) and Class C (energised electrical) fires.

Carbon dioxide extinguishers are filled with non-flammable carbon dioxide gas. The CO2 fire extinguisher can be easily identified by its hard horn and lack of pressure gauge.

Class B Fires: Flammable liquids, gases, solvents, oil, greases, tars, oil-based paints and alcohol based products.

Class C fires: Energised electrical equipment.

Carbon dioxide cuts off the oxygen supply and brings down the temperature of the fire with its cold presence. Once the CO2 gas has extinguished the fire, it will dissipate into the atmosphere without leaving a trace.

No residue typically means no damage. This is a big advantage for expensive electronic equipment, versus using a typical powder fire extinguishers, due to the corrosive nature of the powder used.
