Carbon dioxide fire extinguishers

Carbon dioxide

— such fire extinguishers are used to extinguish liquid and solid substances, as well as electrical installations under voltage. The principle of their operation is based on the release of pressurized gas to the source of the flame. The released carbon dioxide knocks down the flame, cools the source of ignition and forms a dome around the ignition localization, preventing the access of oxygen. An exception for carbon dioxide fire extinguishers are substances that can burn without oxygen.
