If the cabin is filled with smoke at floor level, how should passengers behave?

• A. Stand upright and cover your nose with a scarf.
• B. Run toward the cockpit to alert the crew.
• C. Stay low to the floor and move toward the closest exit.
• D. Remain seated and wait for instruction.

Answer: (C)

When smoke fills the cabin, the air near the floor is clearer and cooler while heat and heavier smoke rise toward the ceiling. Staying low lets you breathe less contaminated air and gives you a better chance to reach safety. Move toward the nearest usable exit in a calm, deliberate manner, keeping low as you go so you’re less exposed to smoke and can navigate around obstacles. If you can, cover your nose and mouth with a cloth to reduce inhalation, and listen to the crew for guidance.

The other options don’t fit because standing upright exposes you to more smoke and heat, rushing toward the cockpit isn’t a safe or practical way to evacuate, and remaining seated delays your escape when every second counts.
