What can be done for the passengers during a fire?

• A. Open cabin doors
• B. Move passengers away from the fire
• C. Turn off air vents
• D. Keep head down and breathe through clothes

Answer: (C)

When a fire breaks out in the cabin, controlling where the air goes is crucial. The ventilation system can carry smoke and hot gases quickly throughout the cabin, increasing exposure for everyone. Turning off the air vents limits that circulation, helping keep breathing air cleaner and slowing the spread of smoke. It also reduces the fresh air feeding the fire, which can help slow its growth until suppression or evacuation. Opening cabin doors would introduce more oxygen and could spread the fire and smoke to other areas. Moving passengers away from the fire is helpful if feasible, but may not always be practical and doesn’t address airflow directly. Keeping heads down and breathing through clothes provides personal protection but does not tackle the spread of smoke or the fire itself as effectively as turning off the vents.
