What is the first step in responding to an electrical fire?

Turning off the power to the electrical source is the first step in responding to an electrical fire because it eliminates the ongoing source of electricity fueling the fire. Without power, the risk of electric shock is significantly reduced, making it safer for individuals trying to contain or extinguish the fire. Additionally, when the power is disconnected, it helps to prevent the fire from reigniting once it is extinguished.

Using water on an electrical fire can be extremely dangerous because water can conduct electricity, potentially leading to severe injury or death to anyone attempting to extinguish the flames. Calling emergency services is also an important step, but it should follow the immediate action of cutting off the power to ensure safety. While a foam extinguisher may be effective for certain types of fires, the priority must be to first address the electrical source to avoid escalating the hazardous situation.
