In an oven incident with only smoke, what action is advised?

• A. Switching off electrical power and keeping the door shut
• B. Open oven and waft the smoke out
• C. Ventilate cockpit
• D. Call for help

Answer: (A)

When a galley oven shows smoke but no flames, the priority is to isolate the potential electrical fire and keep the smoke contained. Switching off the electrical power removes the energy feeding the oven, and keeping the door shut limits the amount of oxygen that can reach hot components and prevents smoke from circulating into the cabin or cockpit. Opening the oven or wafting the smoke out would introduce fresh air and could feed any fire or spread smoke, making the situation harder to control. Ventilating the cockpit doesn’t address the source and could draw more smoke toward the crew. Calling for help is important, but the immediate best action is to power down the oven and keep the door closed, then follow established procedures to manage the situation.
