Question 1

True or False: A watertight door between two compartments should be kept closed while underway unless someone is actively passing through it, even if one of the compartments seems low-risk (like a garage or storage space).

Accepted Answer

True True. On the yacht Lovebug, an open external door and an open watertight door between a garage space and the engine room compartment let water flow freely between spaces once it reached the lower door's edge — the vessel listed to 45-50° and everyone aboard was in the water within about four minutes. A watertight door left open removes the entire point of having watertight subdivision.

Question 2

You're asked to test a deck crane grab after electrical repairs nearby. As the grab is hoisted, what should have happened first?

Accepted Answer

The area within the grab's swing radius should be cleared of personnel before the lift On the bulk carrier Fairfield Eagle, a crew member working nearby was struck and fatally injured when a grab being test-lifted after repairs swung unexpectedly. The investigation found the area should have been cleared and barriered before the test lift began.

Question 3

A toolbox talk held before a lifting operation should explicitly cover which of the following?

Accepted Answer

Who must remain clear of the exclusion zone while the lift takes place A toolbox talk exists to make sure everyone present understands the danger zones, the abort signal, and — critically — who must not be in the area while the lift happens. The RMIMA investigation into the Fairfield Eagle fatality found the toolbox talk had not made this clear.
