Which type of fire extinguisher is specifically used for electrical fires?

The correct answer is the extinguisher specifically used for electrical fires, which is Class C. Class C fire extinguishers are designed to handle fires that involve energized electrical equipment. The extinguishing agents used in these types of extinguishers do not conduct electricity, making them safe and effective for use on electrical fires.

Class C extinguishers typically utilize agents like carbon dioxide (CO2) or dry chemical powders, which can put out fires without putting the user at risk of electrical shock. On the other hand, Class A fire extinguishers are suited for ordinary combustibles like wood and paper, Class B is for flammable liquids such as gasoline and oil, and Class D is specifically designed for combustible metals, which do not include electrical components. This specificity ensures that firefighters and personnel can effectively respond to electrical fires without endangering themselves or exacerbating the situation.
