Which type of fire should NOT be extinguished with water?

• A. Electrical fires
• B. Wood fires
• C. Paper fires
• D. Fabric fires

Answer: (A)

Water should not be used to extinguish electrical fires because water is a conductor of electricity. When water is applied to an electrical fire, it can cause the fire to spread and increase the risk of electric shock to the person attempting to extinguish it. Instead, the best approach for electrical fires is to use a fire extinguisher specifically designed for electrical fires, such as Class C extinguishers, or to shut off the power source if it is safe to do so before attempting to extinguish the fire. In contrast, wood, paper, and fabric fires are typically Class A fires, which can be effectively extinguished with water. Water works to cool the flames and reduce the temperature of the combustible materials, making it effective for these types of fires. Therefore, the rationale for avoiding water on electrical fires highlights the importance of understanding the nature of different fire types and the methods suitable for extinguishing them safely.
