Grasping safe handling of a CO2 Portable Fire Extinguisher is a vital part of fire safety. Properly use the extinguisher for any effective fire control. When using an accurately positioned extinguisher, always remember to pull the pin, aim at the fire at the base, squeeze the handle, then sweep side to side. The Co2 Portable Fire Extinguisher was intended for use on electrical fires and liquid flammable fires. It should never be used on paper or wood fires. Properly hold the nozzle to avoid frostbite. When handled correctly, you can safely deal with small fire emergencies before they escalate into major accidents.
