What is the first step to take in case of a Charlie fire in a switchboard at EPCC?

Isolating the power source is a critical first step in responding to a Charlie fire, which refers to a fire involving energized electrical equipment. When a fire occurs in a switchboard, it is essential to eliminate the electrical supply to the affected area to prevent the risk of further electrical hazards, including potential shock or additional fire spread.

Activating the fire sprinkler system or manually attempting to extinguish the fire without isolating power could lead to more dangerous situations, such as electrical shock or the fire worsening due to additional current flow. While notifying emergency services is important, it is not the immediate action to take when dealing with a Charlie fire—prioritizing the safety of personnel by eliminating power first is paramount. This ensures a safer environment for both responders and individuals in the vicinity.
