According to How Stuff Works, fire extinguishers use carbon dioxide to displace the oxygen necessary for a fire to burn, extinguishing the blaze. Fires need oxygen, fuel, and heat to ignite, and removing any one of those three components can put out a fire. Carbon dioxide extinguishers work because carbon dioxide molecules are heavier than oxygen …
The Use Of Carbon Dioxide For A Fire Suppression Agent. There are many advantages CO2 can offer to fire extinguishing purposes. Portable C02 extinguishers can be used on electrical wiring and equipment. A fire can only happen when fuel, oxygen and heat are present. The C02 extinguishes the fire by attacking fuel, oxygen and heat.
Why Is Carbon Dioxide Used in Fire Extinguishers? | eHow
CO2 is effective on liquid fires, gaseous fires and electrical fires (American classes B and C and International classes B, C and E). The gas is particularly useful for electrical fires as it’s non-conductive and leaves no trace after …

What are the two ways to extinguish a fire?
One method is Total Flooding, which is when an enclosure is filled with CO2 vapor to combat surface-type (liquid fuels) and deep-seated fires. The second method is local application, which can only extinguish surface fires in flammable liquids, gases, and shallow solids (dip tanks, spray booths, printing presses and quench tanks).
Is carbon dioxide a fire suppressant?
At the minimum design concentration (34 percent) for its use as a total flooding fire suppressant, carbon dioxide is lethal.
Can you use CO2 to put out a fire?
CO2 is effective on liquid fires, gaseous fires and electrical fires (American classes B and C and International classes B, C and E). The gas is particularly useful for electrical fires as it’s non-conductive and leaves no trace after its use (as would be the case for foams or other gases).
