The suitable type of fire extinguisher for electrical fires is the Class C extinguisher. Class C extinguishers are specifically designed to extinguish fires that involve electrical equipment such as wiring, circuit breakers, and appliances. The extinguishing agents used in Class C extinguishers are non-conductive, which means they do not pose a risk of conducting electricity. This property is crucial for safely extinguishing electrical fires without increasing the risk of electric shock to the user.

Understanding the classifications is vital for fire safety; Class A extinguishers are for ordinary combustibles like wood and paper, Class B extinguishers are for flammable liquids, and Class D extinguishers are used for combustible metals. Using the wrong type of extinguisher on an electrical fire can be dangerous and ineffective, as non-class C extinguishers may conduct electricity and lead to serious injury or exacerbate the fire. Therefore, it's essential to use a Class C extinguisher for electrical fires.
