How should you don and adjust a life vest?

• A. Inflate before wearing
• B. Put it over the head, fasten the side straps, tighten securely, and ensure it does not obstruct movement or exits.
• C. Remove the vest after use
• D. Put on after deplaning

Answer: (C)

The key idea is to ensure the vest fits securely and won’t interfere with movement or exiting the aircraft in an emergency. Put the vest on by pulling it over your head, slide your arms into the armholes, and fasten the side straps. Then tighten the straps until the vest sits snugly but comfortably—too loose and it could rise or slip; too tight and it could restrict breathing or movement. The vest should stay in place as you move toward exits or a raft, and you should be able to reach inflation mechanisms or oral tubes if applicable without hindrance.

Inflating the vest is not done before wearing it. Most life vests are designed to be inflated when you are ready to float in the water or as directed by crew, using the inflation mechanism or by mouth if provided. Removing the vest after use defeats its protective purpose, and putting it on only after deplaning misses the critical time when you’d need buoyancy.
