What is the recommended action when using a fire extinguisher on an electrical fire?

Shutting off the electrical current is a crucial action when dealing with an electrical fire because it removes the source of the electricity that is sustaining the fire. This not only helps to prevent further escalation of the fire but also significantly reduces the risk of electrocution for the individual attempting to extinguish it.

Before attempting to use a fire extinguisher, ensuring that the power supply is cut off allows for safer engagement with the fire, as water and other agents can conduct electricity and pose a significant danger. Additional measures, such as using foam or powder extinguishers, are also relevant, but making sure the electrical source is deactivated takes precedence for safety. Evacuating the area may be necessary in severe cases, but addressing the electrical source should be the first priority in a contained scenario.
