Class C fires involve which of the following?

Class C fires specifically involve electrical equipment and appliances. These fires can occur in a variety of environments, including residential and commercial settings, where electrical wiring, devices, and systems can overheat, short-circuit, or suffer damage that leads to combustion. It is crucial to identify these fires correctly because the approach to extinguishing them differs significantly from other classes of fires. For instance, using water on a Class C fire can be extremely dangerous due to the risk of electrocution. Instead, appropriate fire extinguishing agents for Class C fires include non-conductive dusts or chemical agents specifically designed to handle electrical fires safely.

The other options pertain to different classes of fires: wood and paper relate to Class A fires, burnable fuels to Class B fires, and chemical reactions could describe Class D fires, which involve combustible metals. Understanding these categorizations helps in applying the right methods for fire prevention, control, and safety measures.
