Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well. CO2s may be ineffective at extinguishing Class A fires because they may not be able to displace enough oxygen to successfully put the fire out.Class A materials may also smolder and re-ignite.

The Extinguisher Cannisters contain the carbon dioxide in liquid form.
◾These are used to overcome electrical fire risks and are usually the main fire extinguisher type that is provided in computer server rooms.
◾Carbon Dioxide (CO2) Extinguishers contain co2 in liquid form and when it relased the co2 gets neutralized by the oxygen present in the air and
thus it reduces the intensity of the flame by blocking the flow of oxygen which supports fire/flame
◾It disables the fires ability to spread and due to this blocking of oxygen the fire gets stops.
