2kg Carbon Dioxide Co2 Fire Extinguisher.

CO2 extinguishers are primarily used for Class B (flammable liquids like petrol and oil) and Class E (electrical) fires. They work by displacing oxygen, which suffocates the fire. The extinguisher releases a cloud of "snow" which is carbon dioxide gas. A key advantage of using a CO2 extinguisher on electrical fires is that it does not leave any residue, making it safe for use on sensitive equipment like computers and servers.
