What type of fire extinguisher is effective against electrical fires?

Class C fire extinguishers are specifically designed to combat fires that involve electrical equipment. This includes fires that originate from wiring, electrical motors, transformers, or any device that operates with electricity. The extinguishing agent in Class C extinguishers is non-conductive, meaning it can safely be used on live electrical fires without posing a risk to the user or worsening the situation.

In contrast, Class A extinguishers are appropriate for ordinary combustibles such as wood or paper, Class B extinguishers are meant for flammable liquids and gases, while Class D extinguishers are used for combustible metals. Using the wrong type of extinguisher on an electrical fire can lead to dangerous consequences, such as electrocution or exacerbating the fire, making the correct identification of Class C extinguishers crucial for safety.
