What should be done if an electrical fire occurs?

• A. Use water to extinguish it
• B. Unplug all devices
• C. Use appropriate fire extinguisher
• D. Evacuate the building immediately

Answer: (C)

In the case of an electrical fire, the most effective and safe response is to use an appropriate fire extinguisher specifically designed for electrical fires, such as a Class C extinguisher. These extinguishers typically contain non-conductive agents that can safely put out the flames without conducting electricity. This is crucial because using water, as indicated in another response, can be extremely dangerous due to the conductive nature of water, which can lead to electrocution.

While unplugging devices might seem like a logical step, it is often unsafe to approach or attempt to unplug any equipment during an active electrical fire, as it can increase the risk of electric shock. Furthermore, immediate evacuation is essential in many cases, but it should be combined with the appropriate fire extinguisher use if it is safe to do so. However, the ideal response within the question's context emphasizes the direct action of using a fire extinguisher designed for electrical fires to contain and extinguish the flames effectively.
