The 5lb CO2 Fire Extinguisher is a specialty fire extinguisher that operates differently than the standard and commonly used ABC Fire Extinguisher. The CO2 fire extinguisher eliminates fires by smothering the flames with CARBON DIOXIDE. CARBON DIOXIDE is discharged as a white cloud of “snow” which smothers a fire by eliminating oxygen. It is effective for Class B flammable liquid fires and Class C Electrical fires as the CO2 is electrically non-conductive. Carbon Dioxide is a clean, non-contaminating, odorless gas which does not leave a mess like standard ABC Fire Extinguishers.
