What should be done when using a water extinguisher on an electrical fire?

It is safe to use
Avoid using it
Only use if no other extinguishers are available
Soak the area surrounding the fire

The correct answer is: Avoid using it

Using a water extinguisher on an electrical fire is extremely dangerous due to the nature of electricity and water. Water is a conductor of electricity, which means using it on an electrical fire can create a risk of electric shock for the person trying to extinguish the fire. This is particularly critical because electric currents can spread through the water, effectively increasing the risk of injury or even death. The best practice in the event of an electrical fire is to use a specifically rated extinguisher, such as a CO2 or dry powder extinguisher, which are designed to safely extinguish electrical fires without conducting electricity. These extinguishers are made to handle fires involving live electrical equipment without the risk associated with water exposure. In summary, avoiding the use of water extinguishers on electrical fires is a crucial safety measure for both the individual and the surrounding area.
