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

• A. Water-based extinguishers
• B. Class K extinguishers
• C. Class C extinguishers
• D. Foam extinguishers

Answer: (C)

For electrical fires, the most suitable type of fire extinguisher is Class C. This classification specifically applies to fires that involve electrical equipment, such as wiring, appliances, and other electronic devices. Class C extinguishers typically contain non-conductive agents like carbon dioxide (CO2) or dry chemical powders that safely extinguish the fire without posing a risk of electrical shock.

Using a water-based extinguisher, as indicated in the first option, would be inappropriate for electrical fires because water conducts electricity and could result in electrocution. Class K extinguishers are designed for kitchen fires involving cooking oils and fats, and while very important in that context, they are not suited for electrical fires. Foam extinguishers are effective on flammable liquids and solids but are not safe for electrical fires due to the risk of electric shock when water or conductive agents are introduced.

Thus, Class C extinguishers are specifically intended to handle electrical hazards without compromising safety.
