Question 1

Why might a Totally Enclosed Motor Propelled Survival Craft (TEMPSC) be considered a "dangerous/enclosed space", and what precaution is needed before personnel board it for an abandon ship drill or emergency?

Accepted Answer

A TEMPSC is a small, enclosed compartment that may have an atmosphere affected by engine exhaust fumes, off-gassing from batteries or stored equipment, or limited natural ventilation, particularly if it has been closed up for a period — so before boarding (especially after the boat has been closed for some time), the space should be ventilated and, where there is doubt, the atmosphere checked before personnel remain inside for an extended period A TEMPSC is a small, largely sealed compartment, and incidents have highlighted risks of dangerous atmospheres developing inside — for example, batteries reacting and releasing hydrogen or other gases, engine exhaust products if the engine is run with the boat closed up, or simply a build-up of carbon dioxide from occupants in a poorly ventilated space over time. Before personnel spend extended periods inside (e.g. during drills, or in an actual emergency where the boat may need to remain closed), the boat should be ventilated (hatches/openings opened where safe to do so) and consideration given to checking the atmosphere if there is any reason for concern, particularly if the boat has been closed up for some time or if battery/engine issues are suspected.

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.
