Question 1

True or False: If a hatch or door into a cargo hold access space has been closed for the whole voyage, you can assume the space beyond it is safe to enter without testing, as long as it feels well-ventilated.

Accepted Answer

False Federal Indiana's booby hatch cover was the only barrier between the CH No.1 Access Space and a cargo hold assessed as oxygen-depleting and toxic — once the cover was opened for inspection, gas could migrate into the space regardless of how it was normally ventilated. You cannot visually confirm a hatch cover's seal is intact; treat a connected space as hazardous until proven otherwise.

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.
