Question 703Deck General70% to pass

Your vessel is loading Class 1 explosives using the vessel's cranes. What style of hook or shackle are you required to use to attach the lifting sling to the runner?

AI Explanation
The correct answer is C) a hook that has been closed by wire. The regulations require the use of a hook that has been closed by wire or other positive means when handling Class 1 explosives. This is to prevent the hook from accidentally opening and allowing the cargo to be dropped, which could be extremely hazardous. The other options are not suitable - a safety hook with the latch open (A) would not provide the necessary security, an open hook (B) is not allowed, and a screw-pin shackle (D) is not the appropriate attachment device for this type of lifting operation.
