What should be checked regularly about a stowed immersion suit, even if it has never been used?

A. Checking is only required after the suit has actually been used in an emergency

B. Only the colour of the suit needs checking, to ensure high visibility

C. Check the suit for damage, deterioration of the rubber/material (cracking, perishing), that zips operate freely, that the size is correct for the intended wearer, and that it has not passed any manufacturer-specified service or inspection date

D. Immersion suits never degrade in storage and require no periodic checking once issued

A. There is no requirement to check personal survival equipment individually — the safety officer checks it on behalf of the whole crew

B. Only once the first boat drill is scheduled, which may be several days after joining

C. Only senior officers need to confirm the location of survival equipment; ratings are shown only during drills

D. Immediately, as part of the mandatory familiarisation process before the vessel sails — every seafarer must know exactly where their personal survival equipment is stowed and confirm it fits and is in good condition, not wait for the first scheduled drill

A. Lifejackets should be worn under outer clothing to keep them protected from sea spray

B. Put on warm clothing first if time allows, then the lifejacket over the top (never under clothing), secure all straps including the crotch strap if fitted, and check the light and whistle are attached and functioning

C. Put the lifejacket on first, then add warm clothing over it for extra insulation

D. Only secure the chest strap — leg/crotch straps are optional and rarely needed in practice
