Question 1

The chief officer entered No. 3 Port cargo tank without a personal gas detector, despite it being both a company requirement and a stated condition on the permit he had just signed. What did the investigation conclude about the atmosphere at the point of entry?

Accepted Answer

It was likely oxygen deficient, at least in the lower portion of the tank The chief officer was found unconscious and breathing weakly, and the Master reported difficulty breathing while unmasked inside the same tank — both consistent with an oxygen-deficient atmosphere, even though the gas-freeing fan had run 11-12 hours. Runtime alone didn't guarantee the tank was actually cleared, because the partially open dome hatches defeated the pressure the system's PV valves needed to vent effectively.

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.
