What type of fire involves live electrical equipment?

Class C fires involve live electrical equipment. This categorization is crucial because water and other common extinguishing agents used for Class A and B fires can conduct electricity and pose a risk of electrocution if applied to energized electrical equipment. Instead, Class C fires should be tackled using extinguishing agents that are safe for use around electrical hazards, such as carbon dioxide (CO2) or dry chemical extinguishers.

Class A fires involve ordinary combustible materials like wood and paper. Class B fires involve flammable liquids and gases. Class D fires are specifically related to combustible metals. None of these classifications address the risks associated with electricity in the same way that Class C does, making it clear why understanding electrical fire hazards is essential for safety.
