PSCRB exit exam questions and answers — Set 6

Set 6 of the Proficiency in Survival Craft and Rescue Boats (PSCRB) exit exam bank — 10 of 160 questions, with the correct option marked and a one-line explanation for every one. Read it end to end, jump to a single set, or search it — then sit the same bank as a timed paper. The real DG Shipping exit exam is 30 marks with 15 to pass.

These are the bank's original groupings. Practising deals the whole bank out again every time you reshuffle, so a practice “Set 3” is a different 30 questions each time — the set numbers below are the source file's, and are only used here so the key stays navigable. Options are listed in their original order with fixed letters; when you practise, those move too.

Set 6 — 10 PSCRB exit exam questions with answers

1. What is the function of the hydrostatic release unit (HRU) test pin / indicator?

  • A. Indicates HRU expiry date and verifies internal spring diaphragm seal integrity
  • B. Starts lifeboat engine
  • C. Measures water salinity
  • D. Fires signal rocket
Answer: A — Indicates HRU expiry date and verifies internal spring diaphragm seal integrity
HRU inspection verifies valid expiration date markings (2-year service life for disposable HRUs) and absence of physical damage.

2. What safety equipment must be worn by all crew members during lifeboat launching drills?

  • A. Approved lifejacket, hard hat with chin strap, protective footwear, and suitable work clothing
  • B. Swimwear only
  • C. Raincoat without lifejacket
  • D. Cotton gloves only
Answer: A — Approved lifejacket, hard hat with chin strap, protective footwear, and suitable work clothing
Safety rules mandate lifejackets, helmets with chin straps secured, and safety boots during all survival craft launching drills.

3. What is the primary action to stabilize a person rescued from cold water who is suffering from mild hypothermia?

  • A. Remove wet clothing, wrap in warm dry blankets/TPAs, shelter in warm room, give warm sweet drinks if conscious
  • B. Give alcohol or hot coffee immediately
  • C. Place in hot bath at 50 degrees C
  • D. Rub limbs vigorously with snow
Answer: A — Remove wet clothing, wrap in warm dry blankets/TPAs, shelter in warm room, give warm sweet drinks if conscious
Re-warming must be gradual passive insulation; alcohol causes peripheral vasodilation leading to severe blood pressure drops ('after-drop').

4. What is the function of the drain valve (auto-drain valve) fitted in the bottom of a lifeboat hull?

  • A. Automatically drains rainwater when boat is stowed on davits, and seals automatically when boat enters sea water
  • B. Drains fuel oil into sea
  • C. Admits sea water to sink boat
  • D. Cools engine sump
Answer: A — Automatically drains rainwater when boat is stowed on davits, and seals automatically when boat enters sea water
Automatic bottom drain valves use a buoyant ball that drops open to drain rainwater when stowed, but seals upward under sea water pressure.

5. What capsize recovery system is fitted to rigid rescue boats?

  • A. Self-righting frame with inflatable CO2 transom bag activated automatically or manually when inverted
  • B. Heavy lead keel ballast
  • C. Dual outboard motors
  • D. Automatic parachute
Answer: A — Self-righting frame with inflatable CO2 transom bag activated automatically or manually when inverted
Rigid rescue boats incorporate an aft self-righting gantry carrying an inflatable buoyancy bag that rights the boat immediately if capsized.

6. What is the function of the emergency tiller supplied with a lifeboat?

  • A. Connects directly to top of rudder stock to steer manually if steering wheel linkage breaks
  • B. Starts engine manually
  • C. Operates bilge pump
  • D. Locks davit brake
Answer: A — Connects directly to top of rudder stock to steer manually if steering wheel linkage breaks
If helm cable/hydraulic remote steering fails, the emergency steel tiller drops over the squared rudder head stock for direct mechanical steering.

7. What quantity of thermal protective aids (TPAs) is required in a lifeboat equipped for 100% of its complement?

  • A. TPAs for 10% of the passenger capacity or 2 TPAs (whichever is greater), unless immersion suits are provided for all
  • B. None required
  • C. 1 TPA per person always
  • D. 50 TPAs fixed
Answer: A — TPAs for 10% of the passenger capacity or 2 TPAs (whichever is greater), unless immersion suits are provided for all
SOLAS III/32 requires TPAs for 10% of capacity (min 2) in lifeboats, or 100% if uninsulated immersion suits are carried.

8. What is the requirement for testing a lifeboat diesel engine during routine weekly inspections?

  • A. Run engine in ahead and astern gear for at least 3 minutes (or per manufacturer guidance) to verify starting and transmission
  • B. Run engine for 24 hours continuously
  • C. Crank engine without fuel
  • D. Test engine only in drydock
Answer: A — Run engine in ahead and astern gear for at least 3 minutes (or per manufacturer guidance) to verify starting and transmission
Weekly SOLAS checks require starting the engine, checking oil/cooling parameters, and engaging forward and reverse gear clutches.

9. What device inside a lifeboat displays engine cooling water temperature, oil pressure, and battery charging voltage?

  • A. Engine instrument gauge panel at the coxswain station
  • B. Ship bridge ECR monitor
  • C. SART display
  • D. Portable multitester
Answer: A — Engine instrument gauge panel at the coxswain station
Lifeboat engine controls include a waterproof instrument panel monitoring RPM, lube oil pressure, coolant temperature, and battery charge.

10. What is the primary objective of Proficiency in Survival Craft and Rescue Boats (PSCRB) training?

  • A. To take command of a survival craft or rescue boat during and after launch, operate engines, manage survivors, and use location devices
  • B. To navigate commercial cargo ships across oceans
  • C. To overhaul main engine turbochargers
  • D. To conduct port customs clearance
Answer: A — To take command of a survival craft or rescue boat during and after launch, operate engines, manage survivors, and use location devices
PSCRB training under STCW Code Table A-VI/2-1 ensures seafarers can launch, operate, lead, and survive in survival craft and rescue boats.
