We are offering here the Co2 Fire Extinguisher that is a portable, active fire protection device that works by expelling carbon dioxide onto a fire. It works by displacing the oxygen the fire relies upon to continue burning, and it is primarily used to extinguish fires in which the source of the fuel is a flammable liquid or gas. The extinguishers are the extinguisher of choice for electrical fires. These extinguishers work on flammable liquid (class B) fires. As the CO2 gas is expelled it turns into a cloud of dry ice, commonly referred to as snow. Co2 Fire Extinguisher is very safe for use.
