Question 1

On VHF radio, why is Channel 16 significant, and what is it generally used for?

Accepted Answer

Channel 16 is the international VHF distress, safety and calling channel — vessels monitor it while under way, and it's used to make initial contact (including Mayday and Pan Pan calls) before typically being asked to switch to a working channel for routine conversation, keeping 16 clear for genuine emergencies Channel 16's role as the international calling and distress channel is one of the first practical VHF facts new crew learn — keeping it monitored and free of routine chatter (moving to a working channel once contact is established) is what keeps it genuinely useful in an actual emergency, which is the entire point of the convention.

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.
