276. 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. Which action should you take?

A brief whistling sound from a raft's safety valve after inflation is normal pressure relief and should not be alarming unless it persists or the raft loses pressure. Tampering with safety valves or deflation plugs can compromise the raft's buoyancy and structural integrity, and is not recommended.
