Which fire extinguisher type would you use for a Class C fire?

A Class C fire involves energized electrical equipment, making it essential to use an extinguisher that does not conduct electricity. Carbon dioxide (CO2) extinguishers are particularly effective for this type of fire. They work by displacing oxygen, which is necessary for combustion, without leaving any residue that could damage electrical components.

CO2 extinguishers are safe to use on electrical fires because they do not contain water or chemicals that could conduct electricity. This property makes them ideal for extinguishing fires in electrical equipment, ensuring that the fire can be safely put out without increasing the risk of electric shock or further damage.

While other extinguishing agents, like dry chemicals, could also be used on Class C fires, CO2 is preferred in many situations because it is clean, doesn’t create a mess, and eliminates the risk of re-ignition. Therefore, opting for a CO2 extinguisher is the correct choice for effectively and safely addressing a Class C fire.
