What is the first action when a cabin decompression occurs?

• A. Put on a mask
• B. Call the captain
• C. Grab oxygen
• D. Sit down

Answer: (C)

During cabin decompression the immediate priority is to breathe oxygen. Oxygen masks automatically deploy, and the first action is to put your own mask on and secure it so you can breathe normally and stay conscious. Once you’re breathing well, you can assist others if you’re able. The idea of grabbing oxygen isn’t how it works—oxygen comes through the mask, not something you grasp by hand. Sitting down won’t address the urgent need for oxygen, so it isn’t the right first move.
