What is the first step in the rapid decompression procedures?

• A. Sit + secure - don oxygen
• B. Open the cabin door
• C. Stand up and stretch
• D. Return to the seat

Answer: (A)

In rapid decompression, the immediate dangers are a sudden loss of cabin pressure and the risk of being injured by uncontrolled movement. The first priority is to protect yourself and start breathing oxygen as quickly as possible. Sitting down, securing your seat belt, and donning oxygen keeps you restrained so you’re less likely to be tossed around and ensures you have immediate access to the oxygen supply.

Opening the cabin door isn’t feasible or safe during flight and would make the situation worse. Standing up or reaching for other actions wastes precious seconds and increases the chance of injury, while returning to the seat is not the initial step if you’re not already in a safe seated position.
