What specific fall and entrapment hazard exists when carrying out maintenance work on or near a lifeboat/rescue boat davit, compared with general mast or funnel work aloft?

A. The only hazard is sunburn, since davit work is usually done in daylight

B. There is no meaningful difference — davits present identical hazards to any other elevated structure

C. Davits are always at deck level, so no fall hazard exists

D. The proximity to the lifeboat's own falls, hooks, and release mechanism introduces a risk of inadvertent release or movement of the boat while a person is working near or on it, in addition to the standard fall hazard

A. Yes, but only if the Master personally watches from the bridge wing

B. Yes, provided the AB carries a personal locator beacon

C. No — lone height work should not be authorised regardless of experience or task duration; the Master should direct that the task wait for an observer to be available or be carried out by an alternative method

D. Yes, given the AB's experience and the short duration of the task

A. Wait for the battery to be replaced before taking any action, with the worker remaining in position

B. Continue observing visually and assume everything is fine since the worker hasn't signalled distress

C. Shout instructions down to the worker and consider that sufficient going forward

D. Treat the loss of communication as a trigger to pause the task and recover the worker, since the absence of an agreed backup method means there is no reliable way to receive an instruction or distress call
