What category of fuels includes energized electrical wiring?

Energized electrical wiring is classified as a category of fuel specifically designated as Class C fuels. This classification is critical in fire service terminology because it indicates the presence of electrical hazards, highlighting the unique risks associated with combating fires that involve electrical sources.

Class C fuels include not only energized electrical wiring but also any equipment that is powered by electricity. When firefighting personnel approach a fire involving Class C fuels, they must use caution and employ appropriate firefighting methods, such as using non-conductive extinguishing agents. This is essential to prevent the risk of electrocution and to ensure the safety of both firefighters and civilians in the vicinity of the electrical hazard.

In contrast, Class A fuels are ordinary combustibles like wood, paper, and textiles; Class B fuels pertain to flammable liquids and gases; and Class D fuels involve combustible metals. Understanding these categories helps firefighters to implement the right strategies and techniques for fire suppression and safety.
