You have just abandoned ship and boarded a raft. After the raft is completely inflated you hear a whistling noise coming from a safety valve. You should __________.

Correct Answer: Option B — not become alarmed unless it continues for a long period of time

Safety relief valves on inflatable liferafts automatically vent excess pressure caused by solar heating or initial activation. A brief whistling is normal and stops once internal pressure stabilizes, per USCG and SOLAS lifesaving equipment manufacturing standards under 46 CFR Part 160.
