Question

write a short note on carbon dioxide as fire extinguisher​

Answer 1

Answer:

Carbon Dioxide extinguishers are filled with non-flammable carbon dioxide gas under extreme pressure. You can recognize a CO2 extinguisher by its hard horn and lack of pressure gauge. The pressure in the cylinder is so great that when you use one of these extinguishers, bits of dry ice may shoot out the horn.

CO2 cylinders are red and range in size from 5 lbs to 100 lbs or larger. In the larger sizes, the hard horn will be located on the end of a long, flexible hose.

Answer 2

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.
