Question 1

Why does it matter whether an EPIRB has an integrated GPS receiver?

Accepted Answer

A GPS-equipped EPIRB gives search and rescue a fast, accurate position; a non-GPS unit relies on a slower satellite Doppler calculation that can take much longer and be far less precise A GPS-integrated EPIRB transmits an accurate position within the distress message itself, often within minutes. A non-GPS unit depends on Doppler shift calculations from passing satellites, which can take considerably longer and produce a much less precise search area — exactly the gap that left THE ROLLING STONES's crew without a known position for nearly an hour.

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.
