What is the first priority for crew during a decompression event?

• A. Ensure your own oxygen and safety, then assist passengers
• B. Evacuate passengers immediately
• C. Contact dispatch and air traffic control
• D. Secure cargo and luggage

Answer: (D)

When a decompression occurs, the immediate concern is to protect your own ability to function. Donning your own oxygen mask and ensuring your safety is the first priority. With the rapid loss of cabin pressure, oxygen supply is essential to stay conscious and keep thinking clearly enough to manage the situation and help others. Once you are breathing normally and you’re not at risk of incapacitation, you’re in a better position to assist passengers, give instructions, and coordinate the next actions. Evacuating right away isn’t always possible or appropriate while the aircraft is still unstable or not at a safe landing altitude, and contacting dispatch or ATC, while important, comes after establishing your own safety and starting to help others. Securing cargo and luggage has no bearing on immediate life support and is not a priority in the moment.
