Which fire extinguisher type is suitable for electrical equipment?

1. Type A

2. Type B

3. Type C

4. Type D

The correct answer is: Type C

The appropriate type of fire extinguisher for electrical equipment is Type C. This classification is specifically designed to handle fires that occur in electrical components, wiring, and devices. Type C extinguishers typically use non-conductive agents such as carbon dioxide or dry chemical powders to effectively suppress flames while minimizing the risk of electrical shock. This distinction is crucial because other types of extinguishers, such as those designed for ordinary combustibles (Type A), flammable liquids (Type B), or combustible metals (Type D), would be ineffective or even dangerous when used on electrical fires. Therefore, recognizing the specific classification and intended usage of fire extinguishers is vital for ensuring safety and effective fire response.
