Which procedure addresses handling smoke or fumes in the cockpit or cabin when there is no fire?

• A. Smoke or fumes procedure
• B. Smoke suppression procedure
• C. Cabin depressurization procedure
• D. Oxygen mask procedure

Answer: (A)

Handling smoke or fumes in the cockpit or cabin when there’s no fire is about keeping the air breathable and preventing smoke from spreading while you identify and control the source. The smoke or fumes procedure is the one designed for this exact scenario, guiding you to put on oxygen for the crew and passengers, establish clear communication, and manage the aircraft’s ventilation to isolate the smoke as you work to restore a safe environment and continue the flight. This differs from smoke suppression, which is aimed at putting out a fire; cabin depressurization is about a loss of cabin pressure and uses a different set of steps; and while wearing an oxygen mask is part of the response, the dedicated smoke or fumes procedure provides the complete, structured actions needed for non-fire smoke events.
