Carbon dioxide (CO2) fire extinguishers are often found in kitchens and laboratory spaces, but their use is limited. The gas is extremely cold, and when it reaches the fire, it can reignite the liquid, spreading the flames further. Because of their limited range, they should always be used at a safe distance from the fire. However, they are an excellent option for any fire situation and should be available wherever there is flammable liquid storage.
How to Do CO2 Fire Extinguishers
One way to keep your CO2 fire extinguisher in good condition is to have it regularly inspected. You can do this yourself, or have it checked by a professional. If you have a maintenance contract with a professional company, you may want to get the unit inspected annually. This inspection should be done by someone with experience with CO2 fire extinguishers. In addition, you should have the unit cleaned regularly and protected from damages.
CO2 fire extinguishers are most effective at putting out electrical fires, although they are ineffective against flammable solids like cooking oil. The chemical smothers the fire with no residue, making it the best option for this type of fire. While CO2 extinguishers are great for electrical fires, they are not the best option for flammable liquids or gases.
