If a cabin fire occurs, what should you do with the master switch?

In the event of a cabin fire, turning off the master switch is a crucial step in ensuring safety. The master switch controls the electrical systems in the aircraft, and by turning it off, you can eliminate the source of power that may be fueling the fire or could potentially create sparks that could worsen the situation.

Power to electrical systems can not only help control fires caused by electrical faults but also disengage any equipment that could contribute to the fire or smoke within the cabin. This action helps to prevent further damage and facilitates a clearer course of action for the pilot and crew, enabling a better focus on controlling the situation, including executing potential emergency landing procedures if necessary.

Proper fire management protocols often include shutting off electrical power as a priority to minimize hazards associated with electrical systems. Therefore, turning off the master switch is a direct response in managing a cabin fire effectively.
