CO2 Fire Extinguishers

The main advantage of CO2 fire extinguishers is that they leave no residue after use, which can be important for protecting sensitive and expensive electronic equipment. Other typical areas of application of CO2 fire extinguishers are food preparation areas, laboratories and printing or duplication areas. The CO2 fire extinguisher has a steel cylinder which contains the compressed gas in liquid form. When the lever is pressed, the gas leaves the cylinder and becomes carbonated snow which puts out the fire. Then it turns into dry ice.
