Class C extinguisher

Class C is never seen alone, as it is not a fuel type. Rather it is a complicating factor in fighting a fire of another type, as it means that the fire contains energized electrical components. A fire extinguisher marked with class C simply means that the extinguishing agent will not carry electricity and shock you or others in the area.

Dry chemical extinguishers are available in ABC and BC flavors. Carbon dioxide extinguishers are rated BC. Water mist extinguishers are rated AC, but are rather rare outside of hospitals.
