Your examiner asks: "What is a Thermal Protective Aid (TPA), how many must be carried, and how does it differ in purpose from an immersion suit?"

A. A Thermal Protective Aid is a lightweight, low-bulk bag or suit made of waterproof, low-thermal-conductance material, intended to reduce heat loss from a survivor's body once they are ALREADY in a survival craft or already wearing other protection — it is not a full-body immersion protection garment designed to be worn while entering the water, unlike an immersion suit. The LSA Code requires TPAs to be carried sufficient for a specified minimum proportion of the persons the lifeboat/rescue boat is permitted to accommodate (a small percentage, or a minimum absolute number, whichever is greater), reflecting that TPAs are a supplementary survival-craft item, not a replacement for personal immersion suits which every person on board is separately required to have access to.

B. A TPA and an immersion suit are exactly the same item under two different names, with SOLAS Chapter III requiring only one or the other but never both to be carried.

C. TPAs are designed to be worn in place of a lifejacket while actively swimming in open water and have no role once a person is aboard a survival craft.

D. TPAs are required in a quantity equal to 100% of the total persons on board, identical in scale to the immersion suit carriage requirement.

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
