Carbon Dioxide (CO2) Fire Extinguishers

Inspection | Testing | Service | Sales

Carbon dioxide fire extinguishers store carbon dioxide as a pressurized liquid. When the extinguisher is activated, it quickly evaporates into a gas and blankets the fire with a white cloud of “snow” that smothers the fire and cuts off the oxygen. The biggest advantage of CO2 fire extinguishers is they don’t leave behind any damaging residue, which is important if you’re looking for a fire extinguisher to protect sensitive equipment.

CO2 fire extinguishers are most effective on Class B (liquid) fires, and are electrically non-conductive, making them safe for use on Class C (electrical) fires as well. Common places where carbon dioxide fire extinguishers are used include:

• Food preparation areas
• Laboratories
• Printing or duplicating areas
