In the safety demonstration order, the life vest is demonstrated after the oxygen.

• A. Before oxygen
• B. After oxygen
• C. Simultaneously with oxygen
• D. It is not demonstrated

Answer: (B)

The sequence is designed to address the most immediate safety need first. If cabin pressure is lost, oxygen masks deploy and you must know how to access and use them right away to keep breathing. Demonstrating how to use the oxygen masks first ensures passengers understand a life-support action they must perform immediately, before moving on to other equipment. After passengers understand how to obtain oxygen, the demonstration covers the life vest. The life jacket is for a potential water landing and is shown once the critical breathing issue is addressed, so the information isn’t introducing additional complexity at the moment you’re learning about rapid breathing under depressurization. Also, inflate the vest only after exiting the aircraft, which fits with the overall flow of safety procedures—address breathing first, then prepare for ditching. So, demonstrating the life vest after the oxygen is the best order because it aligns with prioritizing immediate survivable actions and keeps the information progression clear and practical.
