Which areas on the aircraft are designed to contain fire?

• A. Wings and Tail
• B. Cockpit and Cargo Hold
• C. Passenger Cabin and Avionics Bay
• D. Cargo Holds, Waste Bins (Galley & Lavatory)

Answer: (D)

The main idea is isolating a fire so it doesn’t spread to occupied areas. Cargo holds are built as separate, fire-contained compartments with their own detection and extinguishing systems, so a fire there can be kept from reaching passengers or the cabin. Waste bins in the galley and lavatories are enclosed, closeable containers, designed to trap flames or smoke from burning waste and limit its spread into the cabin. Other areas like wings, tail, cockpit, or avionics bay have fire protection and suppression, but they’re not primarily designed as designated fire containment zones in the same way cargo holds and waste bins are. That combination—cargo holds and waste-bin containment—explains why those areas are identified as designed to contain fire.
