Carbon Dioxide fire extinguishers are for class B and C fires. CO2 extinguishers don’t work very well on class A fires due to re-ignition of the material in usual cases. Carbon Dioxide fire extinguishers extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge. CO2 fire extinguishers have an advantage over the DCP fire extinguishers that they leave behind no harmful residue. That makes it a good choice for electrical fire involving computer or other electric energized delicate instruments. Carbon dioxide can be used on Class B & C fires. They are usually ineffective on Class A fires and not approved for class D fires. For the price of Fire Extinguisher
