What is the classification of fires caused by electrical equipment?

The classification of fires caused by electrical equipment falls under Class C. This classification is specifically designated for fires that involve energized electrical equipment, such as wiring, circuit breakers, and appliances. The presence of electrical energy increases the potential for the fire to reignite or continue burning, which is why it is critical to address these fires with appropriate fire extinguishing agents.

Using water on a Class C fire is particularly dangerous, as it can conduct electricity and pose a risk of electrocution. Therefore, extinguishers for Class C fires typically use non-conductive agents like carbon dioxide or dry chemicals, which effectively suppress the fire without posing additional risks to personnel or equipment.

In contrast, the other classifications (Class A, B, and D) correspond to different types of fire sources. Class A involves ordinary combustibles like wood and paper, Class B pertains to flammable liquids, and Class D is related to combustible metals. Understanding these classifications helps in selecting the right fire extinguishing method and ensuring safety when dealing with different types of fires.
