Class C fires involve energized electrical equipment, such as appliances, wiring, and power tools. These fires pose unique hazards because using water or foam extinguishers can conduct electricity, increasing the risk of shock. Instead, Class C fires should be extinguished with non-conductive agents like dry chemical or carbon dioxide extinguishers. Once the electrical source is de-energized, the fire can then be classified as a different type (like Class A or B) if it continues to burn.

This is most often found in certain types of fire extinguishers, and they can be used to extinguish the following: * Class A fires which involve "ordinary combustibles" such as wood, paper, cloth, rubber and many plastics. * Class B fires which involve flammable liquids, oils, greases, tars, oil-based paints and flammable gases. * Class C fires which involve energized electrical equipment. Certain parts of the world use DCP tenders (or tankers). This is a vehicle with a large tank of dry chemical powder. This practice is rare if not unused in the United States, but is found in nations such as India.
