Question 1

As skipper, mounting a petrol-fuelled auxiliary engine inside an enclosed wheelhouse rather than in open air carries no additional fire or explosion risk compared to an open-deck installation.

Accepted Answer

False False. BEAmer's own finding on NINJA II states directly that the presence of the petrol-hydraulic unit inside a confined space like the wheelhouse contributed to the explosion, in the absence of preventive measures. An enclosed space allows vapour to accumulate to dangerous concentrations in a way open air doesn't. [cross-connect: oow, chief_officer — the same enclosed-space vapour-accumulation principle applies to any vessel carrying petrol-fuelled auxiliary equipment, tenders, or generators below deck.]

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.
