Black
Label Colour: Black – Carbon Dioxide (CO2) Extinguishers CO2 extinguishers have black labels and are mainly used for electrical fires, although they are also usually the main type of extinguisher used in computer server rooms. They also put out Class B (flammable liquid) fires.

How do I know if my fire extinguisher is CO2?

You can recognize a CO2 extinguisher by its hard horn and lack of pressure gauge. The pressure in the cylinder is so great that when you use one of these extinguishers, bits of dry ice may shoot out the horn. CO2 cylinders are red and range in size from 5 lbs to 100 lbs or larger.

What is the temperature of a CO2 fire extinguisher?

CO2 suffocates the fire by the displacement/dilution of oxygen in the air. In addition to this, the extinguishing medium comes out at a temperature of -60°C which removes another key player in the fire triangle – heat. This prevents the creation of free radicals and flammable vapours.

Can a CO2 extinguisher explode?
