A Class C fire is defined as a fire that involves electrical equipment. This classification is crucial for fire safety since electrical fires can behave differently from other types and require specific extinguishing methods to prevent electrocution or further equipment damage. The correct approach to extinguishing a Class C fire involves using non-conductive agents, such as carbon dioxide or dry chemical extinguishers, which are selected for their ability to effectively put out the fire without the risk of conducting electricity.

Fires involving flammable liquids are classified as Class B, while fires involving combustible metals fall under Class D. Ordinary combustibles, such as wood, paper, and cloth, are categorized as Class A fires. Each class of fire requires a different firefighting approach and understanding these distinctions is vital for firefighters to act safely and effectively during an emergency.
