Question 1

Mirroring the Equinox Seas case, a fitter on a vessel undergoing shipyard work approaches a space where a ventilation fan has been removed, cordoned off only by a single strip of tape, and the fitter is tired after a long shift. What should the fitter do, and what should the wider system have provided instead?

Accepted Answer

Stop, do not cross the tape barrier, and report that a physical barrier or cover is needed over an opening with this fall consequence — a tape barrier alone is not an adequate control for a hazard of this severity, especially when fatigue increases the chance it will be missed or disregarded A tape barrier is a visual reminder, not a physical safeguard, and is particularly unreliable precisely in the fatigue conditions where someone might most need a barrier to stop them — the Equinox Seas fatality is the real-world consequence of this exact combination.

Question 2

In a documented gangway rigging fatality, what procedural gap was identified regarding how the rigging task was normally carried out by the crew?

Accepted Answer

The rigging of the handrail was understood by the crew to be a two-person evolution, but on the day the bosun proceeded with the task essentially alone after sending the deckhand away for life vests An informally understood 'two-person job' is not the same as a documented, enforced procedure — when the second person was sent away mid-task, there was no formal trigger requiring the work to pause until they returned, which connects directly to the lone-working and procedural-documentation gaps covered elsewhere in this module.

Question 3

According to MAIB Safety Digest reporting on pilot ladder deficiencies, what is a 'choke shackle' arrangement, and why is it dangerous?

Accepted Answer

A shackle secured over the ladder's side ropes rather than properly through the designed attachment point, which brings the entire weight of the ladder onto a single step that is not designed to bear that load One of the most common pilot ladder deficiencies identified by MAIB — it looks like a minor rigging shortcut, but it concentrates load on a structural element (a single step) never designed to carry the ladder's full weight, creating a failure point exactly where a pilot or crew member would be standing.
