Question 1

SELO was carrying wood pellets in bulk in all five holds. What does the Shipper's Cargo Declaration say about the main hazard of this cargo?

Accepted Answer

It depletes oxygen in the hold, and can build up carbon monoxide The declaration identified oxygen depletion as a hazard (along with swelling on exposure to moisture and a dust explosion risk), and required continuous monitoring and recording of oxygen and carbon monoxide in the holds during the passage. The IMSBC Code also notes that wood pellets are subject to oxidation, depleting oxygen and increasing CO and CO2.

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.
