During your oral exam you are asked: what is meant by a "confined space" or "enclosed space" aboard a vessel, and give two examples typically found on a yacht or workboat.

A. A confined or enclosed space is one that has limited openings for entry and exit, inadequate natural ventilation, and is not designed for continuous worker occupancy, where the atmosphere may contain harmful gases, vapours, or have insufficient oxygen, or could become oxygen-deficient/enriched; examples on a yacht or workboat include fuel and water tanks, void spaces, chain lockers, and certain machinery spaces or compartments below the waterline

B. A confined space is defined solely by its physical dimensions, regardless of ventilation or atmospheric considerations

C. Confined spaces only exist on cargo vessels and are not found on yachts or workboats

D. A confined space is any space smaller than a standard cabin, regardless of ventilation or access

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
