What is the correct action on an electrical fire in the cabin?

• A. Use water to extinguish the flames as quickly as possible.
• B. Open the lavatory door to ventilate the area.
• C. Do not use water; use appropriate non-conductive extinguishing media and isolate the source if safe.
• D. Notify the PIC and evacuate immediately without attempting to fight the fire.

Answer: (C)

Electrical fires require a non-conductive approach because water can conduct electricity and put you at risk of shock or spread the fire through energized circuits. The best response is to use an appropriate non-conductive extinguishing agent and, if it can be done safely, isolate the electrical source to stop the current feeding the fire. In practice, grab an extinguisher rated for electrical fires (such as a dry chemical ABC type) and apply it to the base of the flames, keeping safe distances and sweeping motions as needed. If you can disconnect power from the source without endangering yourself or others, do so to prevent re-ignition. After you’ve started suppression, inform the PIC and be ready to evacuate if the situation worsens or smoke persists.
