Which class of fire involves charged electrical equipment?

The class of fire that involves charged electrical equipment is Class C. This classification specifically addresses fires that involve electrical appliances, wiring, and other equipment that may be energized. When dealing with electrical fires, it is critical to use the appropriate extinguishing agents designed for such situations, as using water can create the risk of electrocution or further hazards.

Class C fires are characterized by the presence of electrical equipment, and once the electricity is shut off, the fire may then fall into another class, such as Class A if it involves ordinary combustibles like wood or paper. Each fire class has distinct characteristics and appropriate suppression methods; recognizing the correct classification is vital for effective fire safety education and response.
