What is the key characteristic of a Class C fire?

The key characteristic of a Class C fire is that it involves electrical equipment and wiring. This type of fire arises from malfunctioning electrical devices, short circuits, or energizing electrical equipment that can ignite surrounding materials. The primary concern with Class C fires is that using water as an extinguishing agent can pose a significant risk of electric shock and potentially worsen the situation by allowing the fire to spread.

Class C fires must be handled with specific types of extinguishers, such as those containing carbon dioxide or dry chemical agents that can effectively cut off the oxygen supply without conducting electricity. Recognizing the nature of a Class C fire is crucial for ensuring safety during firefighting efforts and effectively utilizing the appropriate methods for extinguishment.
