What type of fire extinguisher is suitable for electrical fires?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (C)

A Class C fire extinguisher is specifically designed for electrical fires. This classification indicates that the extinguisher uses non-conductive extinguishing agents, making it safe to use on electrical equipment that may still be energized. When an electrical fire occurs, using a water-based extinguisher or one that does not offer the appropriate level of insulation could result in electrocution or further fire hazards.

In contrast, Class A extinguishers are intended for ordinary combustible materials such as wood and paper, while Class B extinguishers are suitable for flammable liquids like gasoline or oil. Class D extinguishers are designated for combustible metals, such as magnesium or sodium, and are specifically engineered to deal with those unique challenges. Each class is distinct in its recommended applications, highlighting the importance of using the correct type to effectively manage different fire scenarios.
