Your examiner asks: "What signalling features must every SOLAS lifejacket incorporate, beyond simply providing buoyancy?"

A. Every SOLAS-approved lifejacket must be fitted with: a WHISTLE, securely attached, to allow a survivor to attract attention audibly; a LIGHT that activates automatically on contact with water (or can be manually switched on), intended to make the wearer visible to searchers at night — LSA Code performance standards specify a minimum light intensity, a defined flash rate, and a minimum burn duration; and RETROREFLECTIVE TAPE fitted to the lifejacket to reflect searchlight or torch beams back toward their source, significantly improving visibility to searching vessels/aircraft at night. These features exist specifically to maximise the chance of a survivor being located, not merely to keep them afloat.

B. SOLAS lifejackets are required to provide buoyancy only — whistles, lights, and retroreflective tape are optional extras with no LSA Code performance requirement.

C. The lifejacket light is required to remain permanently illuminated at all times from the moment of stowage, rather than activating on contact with water or by manual switch.

D. Retroreflective tape is fitted only to immersion suits, never to lifejackets, under the LSA Code.

A. Nothing — a test lift can proceed immediately after repairs

B. Testing should wait until cargo operations begin

C. The area within the grab's swing radius should be cleared of personnel before the lift

D. Only the crane operator needs to be aware the lift is happening

A. Who must remain clear of the exclusion zone while the lift takes place

B. The lunch schedule for the deck team

C. Only the weather forecast for the next watch

D. The cargo manifest for the next port
