Where do the oxygen masks deploy from during decompression?

• A. In seat pockets
• B. In the lavatories
• C. Under seats
• D. Overhead compartments

Answer: (D)

During a rapid loss of cabin pressure, passengers need quick, universal access to oxygen. That’s why the masks are stored in the overhead panels above each passenger in the cabin. When decompression is detected, doors in those panels open and the masks drop down into reach. You pull a mask toward you to start the flow and place it over your nose and mouth, securing it with the elastic band. The other options aren’t used because seat pockets, lavatories, or under-seat areas aren’t the locations where emergency oxygen masks are deployed on most airplanes. Overhead compartments keep the masks accessible and unobstructed for every passenger.
