Carbon Dioxide (CO2) fire extinguishers are most commonly used for Class E fires involving electrical equipment.

As Carbon Dioxide (CO2) is a non-conductive & non-corrosive gas, it is the perfect solution for protecting computer & electrical equipment in the event of a fire.

CO2 fire extinguishers remove the heat element of the fire, as well as reducing the oxygen to the fire.

Carbon dioxide fire extinguishers can also be used on Class B fires.

Advantages of Carbon Dioxide Fire Extinguishers

  • Extremely efficient in confined areas.
  • Non-toxic extinguishing agent, will not harm food, machinery or computer equipment
  • Carbon Dioxide does not leave any residue – No Residue means no clean-up.
  • Non-conductive, safe to use on live electrical equipment.

Disadvantages of Carbon Dioxide Fire Extinguishers

  • Poor “knock down” and short discharge. Not very effective in windy circumstances.
  • This type of extinguisher works by removing the oxygen from the environment, care must be taken in confined spaces to ensure asphyxiation does not occur.
  • Carbon Dioxide is an extremely cold substance, also known as dry-ice. Frost burn can occur if you do not avoid direct contact with the CO2.
  • When discharged, carbon dioxide extinguishers produce a loud noise that may startle those not expecting.
  • Not as simple to re-fill as other types of extinguishers. Often easier and cheaper to purchase a new one than to re-fill.
