Carbon Dioxide (CO2) fire extinguishers are suitable to be used for fighting Class B (flammable liquids) and Class C (electrical) fires. The carbon dioxide gas extinguishes the fire by directing the jet of CO2 gas to the base of the fire, thus covering the air around the fire and reduce the oxygen level at the fire point. This will prevent the fire from spreading further and re-igniting again. CO2 fire extinguishers are extensively used in food industry, electronic factories, ships, electrical plants or rooms, and offices. It is a clean extinguishant agent and does not leave any residue after it has been discharged.
