During rapid decompression, what is the first action a Flight Attendant must take?

• A. Oxygen Mask
• B. Life Vest
• C. Hand Signal
• D. Radio Call

Answer: (A)

Breathing becomes the immediate priority. In rapid decompression, cabin pressure falls and the air can’t supply enough oxygen, so hypoxia can set in within seconds. The first action is for every crew member to put on their own oxygen mask and ensure their own oxygen supply is secure. If you’re not getting enough oxygen, you won’t be able to think clearly or help others, so you fix your own mask first and then assist passengers, give instructions to don masks, and coordinate with the cockpit.

Life vests are for water ditching and aren’t the immediate concern in this scenario. Hand signals and radio calls are important parts of the response, but they don’t take precedence over simply breathing and staying conscious.
