The CO2 extinguisher works well on a flammable liquids or an electrical fire – Types B or C fires. They work well on an electrical fire in that they do not leave a messy residue on delicate electrical equipment such as a dry chemical extinguisher would. The CO2 displaces the oxygen at the surface of the fire, effectively smothering the fire. However, the fire can re-ignite once the CO2 gas dissipates if the ignition source has not been removed.
A CO2 extinguisher has a wide nozzle that locks into place. Do not hold onto the nozzle when firing the extinguisher, this nozzle will get very cold as the CO2 gas is expelled; CO2 gas has a temperature of minus 66C. If you are holding onto the nozzle you will receive a cold burn.
A CO2 extinguisher is not a good choice for a Type A fire, (wood, paper, cloth), because of the force of the CO2 gas being expelled from the extinguisher. When this type of extinguisher is used on a wood, paper or cloth fire, the burning items are blown around the room by the force of the CO2 gas, thereby aiding the spread of the fire. Secondly, a Type A fire will usually re-ignite as soon as the CO2 gas dissipates.
