Carbon dioxide extinguisher is a kind of fire extinguishing agent with low price and easy to obtain and prepare. It mainly relies on asphyxiation and partial cooling to extinguish fire. Carbon dioxide has a high density, about 1.5 times that of air.

Under atmospheric pressure, liquid carbon dioxide will immediately vaporize, generally 1kg of liquid carbon dioxide can produce about 0.5 cubic meters of gas. Therefore, when extinguishing the fire, carbon dioxide gas can exclude the air and surround the surface of the burning object or distribute in a more confined space, reduce the oxygen concentration around the combustible object or in the protection space, and produce suffocation and fire extinguishing. In addition, when carbon dioxide is ejected from the storage tank, it rapidly vaporizes from the liquid to gas, and absorbs some of the heat from the surrounding area, which acts as a cooling effect.

Carbon dioxide has good fluidity, high injection rate, no corrosion of containers and not easy to deteriorate and other excellent properties. Carbon dioxide fire extinguisher compresses liquid carbon dioxide in a small cylinder when pressurized. Most of the carbon dioxide fire extinguisher cylinder is made of copper, and it is ejected when extinguishing the fire to cool down and isolate the air.
