Which type of extinguisher should be used for electrical fires?

Class C fire extinguishers are specifically designed for use on electrical fires, which may involve live electrical equipment. The primary reason for using a Class C extinguisher is that it utilizes non-conductive agents, such as carbon dioxide or dry chemical, to suppress the fire without posing a risk of electric shock to the person using it.

Using the correct type of extinguisher for an electrical fire is crucial, as other classifications may contain materials that can conduct electricity or worsen the fire. For instance, Class A extinguishers are intended for ordinary combustibles like wood or paper, Class B extinguishers target flammable liquids, and Class K extinguishers are designed for cooking oils and fats. Choosing the appropriate extinguisher—like the Class C—ensures safety and effectiveness during emergencies involving electrical equipment.
