Class C fires are fires that involve energized electrical equipment?

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.
