PST Exit Exam • Set 2 Question 9 of 30

What action should survivors take when a rescue helicopter approaches a life raft for winch retrieval?

✓

Direct Answer

Option A: Allow winch hook to touch sea water first to discharge static electricity before touching hook

Helicopter rescue winching procedures dictate that the static discharge cable and winch hook must touch the sea surface before contact. This safely bleeds off high-voltage static electricity accumulated in flight, preventing severe electrical shock to survivors in the life raft.
