What type of fires are considered Class C?

Class C fires specifically refer to those involving electrical equipment such as motors, transformers, and appliances. The distinguishing feature of Class C fires is the presence of energized electrical equipment, which necessitates particular caution when attempting to extinguish the fire. Using the wrong type of extinguisher could lead to electrocution or further ignition of the fire. Therefore, extinguishers designed for Class C fires are often non-conductive and suitable for safely managing these types of incidents, typically using agents such as carbon dioxide (CO2) or dry chemical powders that do not conduct electricity.

In contrast, the other options describe different classes of fires; for instance, fires involving flammable liquids fall under Class B, those involving ordinary combustibles, like wood or paper, classify as Class A, and fires that involve metals are categorized as Class D. Each type of fire requires a specific extinguishing method and agent, highlighting the importance of understanding these classifications in fire safety.
