What type of fire does a Class C designation refer to?

The designation of Class C fires specifically refers to electrical fires that involve energized equipment. This classification is crucial for understanding the particular hazards associated with electrical fires, as they necessitate unique firefighting techniques and extinguishing agents. Using water or certain chemicals could exacerbate the situation, potentially leading to electrocution or further ignition.

Class C fires arise from electrical sources, such as wiring, appliances, or circuits that are live with electricity, making it essential for first responders and individuals to utilize extinguishing methods that do not conduct electricity, such as non-conductive extinguishing agents like carbon dioxide or dry chemical extinguishers. Recognizing this classification helps ensure the safety of both the individuals trying to extinguish the fire and those around them, along with enhancing the effectiveness of the firefighting effort.

In contrast, the other classifications mention different fire sources entirely, like natural disasters, flammable liquids, or solid combustibles, which do not apply to the hazard posed by energized electrical equipment.
