Carbon dioxide fire extinguishing agent is a fire extinguishing agent with more than 100 years of history, inexpensive, easy to obtain, easy to prepare, which mainly relies on the role of asphyxiation and part of the cooling effect of fire. Carbon dioxide has a high density, about 1.5 times that of air.

Under normal pressure, liquid carbon dioxide will immediately vaporize, generally, 1kg of liquid carbon dioxide can produce about 0.5 cubic meters of gas. Therefore, when fighting the fire, carbon dioxide gas can be excluded from the air and surrounded by the surface of the burning object or distributed in a more confined space, reducing the concentration of oxygen around the combustible material or in the protective space, resulting in asphyxiation and fire extinguishing. In addition, when carbon dioxide is ejected from the storage container, it will quickly vaporize from liquid to gas, and absorb some heat from the surrounding area to play a cooling role.

Features and Advantages:


  • CO2 (carbon dioxide) extinguishers are for class B and C fires. They don’t work very well on class A fires because the material usually reignites.
  • CO2 extinguishers have an advantage over dry chemicals in that they leave behind no harmful residue. That makes carbon dioxide a good choice for an electrical fire involving a computer or other delicate instrument. Note that CO2 is a bad choice for flammable metal fires such as Grignard reagents, alkyl lithium, and sodium metal because CO2 reacts with these materials. CO2 extinguishers are not approved for class D fires!
  • Carbon dioxide extinguishers do not have pressure gauges because carbon dioxide is a condensable gas. Thus, pressure does not tell you how much agent remains in the cylinder. Instead, the extinguisher should have a tare (empty) weight stamped on it. To determine the amount of carbon dioxide remaining in the extinguisher, subtract the tare weight from the current weight.



It has excellent properties such as good fluidity, high injection rate, non-corrosive container, and not easy to deteriorate, etc. It is used to extinguish the incipient fires of books, archives, valuable equipment, precision instruments, electrical equipment below 600 volts, and oil. Suitable for extinguishing Class B fires, (such as kerosene, diesel, crude oil, methanol, ethanol, asphalt, paraffin, etc.) Suitable for fighting Class C fires (such as gas, natural gas, methane, ethane, propane, hydrogen, etc. fires.) Fighting Class E fires (fires where objects are burning with electricity)
