What type of fire extinguisher should be used for electrical fires?

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

Answer: (C)

For electrical fires, a Class C fire extinguisher is the appropriate choice. Class C extinguishers are specifically designed for fires involving electrical equipment, such as wiring, circuit breakers, and appliances. These types of fires can be particularly dangerous because water, which is often used in other types of fire extinguishers, can conduct electricity and pose a serious risk of electrocution. Class C extinguishers typically use non-conductive agents such as carbon dioxide or dry chemical powders that can safely extinguish the fire without the risk of electrical shock.

In the context of the other options, Class A extinguishers are meant for ordinary combustible materials, such as wood and paper, and would not be suitable for electrical fires. Class B extinguishers are for flammable liquids and gases, so they are also not appropriate for electrical hazards. Class D extinguishers are intended for fires involving combustible metals, which are not relevant in the case of electrical equipment. Thus, Class C is the safest and most effective option for tackling electrical fires.
