During a smoke event, where should passengers breathe to minimize inhalation?

• A. Near the ceiling
• B. Near the floor
• C. In a ventilated area
• D. In the seat pocket

Answer: (B)

Smoke is hot and lighter than surrounding air, so it tends to rise and collect overhead. Staying near the floor puts you in the part of the cabin with cooler air and less smoke, reducing the amount of toxic fumes you inhale. If you can, keep low, cover your nose and mouth with a cloth if available, and move toward an exit while staying as close to the floor as possible. The other options don’t offer the same advantage: near the ceiling is where most smoke gathers, a ventilated area doesn’t guarantee clean air in a smoke-filled cabin, and the seat pocket provides no usable breathing air.
