CO2 Fire Extinguisher


CO2 Fire Extinguisher Carbon dioxide extinguishers are aimed at preventing the combustion of flammable liquids and electric fires, however, they are not suitable for use on flammable solids, flammable gases, or cooking fat fires.

Carbon dioxide extinguishers are used in a variety of settings, including kitchens, restaurants, and public and private buildings, to extinguish fires. Carbon dioxide, on its own, will not put out a fire. The action is to absorb oxygen in the air, which can provide enough oxygen to burn fuel in a fire. The fire, in turn, needs oxygen to burn. This will slow the rate of the fire’s burning, and limit it.

The advantage of carbon dioxide extinguishers is that they are safe for use in kitchens, restaurants, and pubs. They can be used when working with flammable substances such as cleaning products, paint, oil, gas, and petrol.
