A carbon dioxide (CO 2) fire extinguisher is a portable, active fire protection device that works by expelling carbon dioxide onto a fire. It works by displacing the oxygen the fire relies upon to continue burning, and it is primarily used to extinguish fires in which the source of the fuel is a flammable liquid or gas. Carbon dioxide fire extinguishers are a very common …
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). Advertisement.
What is a Carbon Dioxide Fire Extinguisher? – Safeopedia
A fire can only happen when fuel, oxygen and heat are present. The C02 extinguishes the fire by attacking fuel, oxygen and heat. It mainly attacks oxygen to extinguish a burning fire. However, in a deep-seated fire C02 extinguishes the fire by removing oxygen and decreasing gaseous phase of the fuel. There are two ways to apply CO2 in fire suppression.

From 1975 to the present, a total of 51 carbon dioxide incident records were located that reported a total of 72 deaths and 145 injuries resulting from accidents involving the discharge of carbon dioxide fire extinguishing systems.
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.
