What material is commonly used for fire extinguishers to combat electrical fires?

The primary reason for using Class C extinguishers to combat electrical fires is that these extinguishers are specifically designed to extinguish fires involving electrical equipment. Class C extinguishers typically use non-conductive agents, such as carbon dioxide or dry chemical powders, which help to safely suppress fires without posing a risk of electrical shock.

In contrast, Class A extinguishers are meant for ordinary combustible materials like wood and paper, while Class B extinguishers are suitable for flammable liquids, such as gasoline and oils. Class D extinguishers are used for fires involving combustible metals, which are not relevant in the context of electrical fires. Therefore, using a Class C extinguisher ensures both effective fire suppression and safety when dealing with electrical fire hazards.
