Carbon Dioxide Fire Extinguishers: Uses & Advantages

Fire extinguishers are an essential part of any workplace and home fire safety plan. Carbon dioxide fire extinguishers are one type, designed to eliminate fires that involve combustible materials like paper, wood, and cloth.

Carbon dioxide fire extinguishers contain a pressurized mixture of carbon dioxide gas, which is an effective smothering agent. It has a long history of use as a firefighting agent and operates on the principle of displacing oxygen and removing the heat needed to sustain a fire.

When used to extinguish a fire, the carbon dioxide gas is directed at the base of the fire, where it creates a blanket of gas that suffocates the fire and stops oxygen from reaching the burning material. Carbon dioxide is also cold enough that it helps cool the burning material and decrease the rate of burning.

Carbon dioxide extinguishers are effective on class B and C fires, which are those involving combustible materials like wood, paper, and cloth, as well as flammable liquids and liquids with combustible vapors. These extinguishers are not effective on class A fires, which involve ordinary combustible solids such as wood, paper, and cloth.

Carbon dioxide fire extinguishers have several advantages over other types, including the fact that they leave no residue behind on the area, making them suitable for use on electronic equipment and computers. Additionally, carbon dioxide is non-conductive, making it safe to use on energized equipment.

When using a carbon dioxide extinguisher, it’s important to remember that the gas is heavier than air and will sink, so it should be directed at the base of the fire and not the top. Additionally, the noise generated by the discharging gas can be very loud, so care should be taken to protect the operator’s hearing.

Carbon dioxide fire extinguishers are an essential part of any fire safety plan and should be part of any facility’s overall fire control program. With the right preparation and training, they can be an effective tool for controlling fires and keeping people and property safe.
