Question 1

A permit to work authorises testing a repaired passenger lift from inside the car. Partway through, the technician decides to enter the shaft from another deck to inspect the top of the car. What should happen?

Accepted Answer

Stop. The task has moved beyond the authorised scope, so the permit must be re-assessed, amended or reissued before anyone enters the shaft MAIB found that Arvia's permit-to-work arrangements did not identify that the task had moved beyond its authorised scope. A change in what is being done or where it is being done is the trigger to stop and re-assess.

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.
