One drawback to using carbon dioxide, however, is that its mechanism of fire suppression is through oxygen dilution, and not, as is the case for halon, through chemical disruption of the catalytic combustion chain.
Where is CO2 extinguisher used?
CO2 fire extinguishers are mainly aimed at electrical fires but are also suitable for Class B liquid fires and are used in different ways depending on the type of fire they are being used on. Do not use CO2 extinguishers in small rooms as CO2 gas is poisonous at only 4% concentration and can kill at just 8%.
How does CO2 control fire?
In the fire extinguishers, carbon dioxide is kept in the liquid form under pressure and it can work well on some of the small flammable liquid. When carbon dioxide is released, it expands enormously and cools down. Due to this temperature it brings down and this helps in controlling the fire.
