Co2 fire extinguisher, Capacity : 4.5 Kg

The correct type of extinguisher to use on an electrical fire would be a CO2 type extinguisher. This type of extinguisher works by displacing the oxygen near the fire and this, in effect, smothers the fire. You will usually find a CO2 extinguisher 2kg or 4.5kg, not too far away from electrical equipment. CO2 extinguishers jet out the CO2 at high velocity and you may see particles of dry ice as the mist jets out. The big advantage of using this type of extinguisher on electrical equipment is that it does not leave any residue and therefore, does not usually damage sensitive electrical equipment such as computers.
