PSCRB exit exam questions and answers — Set 6 — Proficiency in Survival Craft and Rescue Boats

Set 6 of the Proficiency in Survival Craft and Rescue Boats (PSCRB) exit exam bank — 30 of 389 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.

1. 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.

2. 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.

3. The safety knife stowed on an inflatable liferaft will always be located ____.

  • A. In one of the equipment bags
  • B. In a special pocket near the forward entrance
  • C. On a cord hanging from the canopy
  • D. In a pocket on the first aid kit
Answer: B — In a special pocket near the forward entrance
LSA Code 4.1.5.1.2 requires a buoyant safety knife stowed in a pocket on the outside of the canopy near the point where the painter is attached, normally at the entrance. This lets the painter be cut immediately after boarding.

4. After abandoning ship, you should deploy the sea anchor from a liferaft to ____.

  • A. Keep the liferaft from capsizing
  • B. Navigate against the current
  • C. Keep personnel from getting seasick
  • D. Stay in the general location
Answer: D — Stay in the general location
The sea anchor (drogue) cuts down the raft's drift, keeping it near the position of the casualty where search and rescue will start. It also helps the raft ride head to sea and steadies its motion.

5. Most lifeboats are equipped with ____.

  • A. Unbalanced rudders
  • B. Balanced rudders
  • C. Contra-guide rudders
  • D. Spade rudders
Answer: A — Unbalanced rudders
Lifeboat rudders are simple unbalanced rudders hung on the sternpost with pintles and gudgeons and worked by a tiller. This simple, robust arrangement is easy to ship and hard to damage.

6. The canopy of an inflatable liferaft should ____.

  • A. Go into place as the raft is inflated
  • B. Be put up after everyone is aboard
  • C. Be put up only in severe weather
  • D. Be used as a sail if the wind is blowing
Answer: A — Go into place as the raft is inflated
LSA Code 4.2.2 requires the liferaft to have a canopy that sets in place automatically when the raft is launched and inflated. Its inflatable arches give occupants immediate protection from exposure.

7. All inflatable liferafts have ____.

  • A. Safety straps from the overhead
  • B. Built-in seats
  • C. Releasing hooks at each end
  • D. Water stabilising pockets
Answer: D — Water stabilising pockets
LSA Code 4.2.4 requires water ballast pockets on the underside of every inflatable liferaft. They fill with seawater when the raft inflates and give stability against capsizing by wind and waves.

8. After abandoning ship, which action should be taken IMMEDIATELY upon entering a liferaft?

  • A. Open the equipment pack
  • B. Issue anti-seasickness medicine
  • C. Get clear of the ship
  • D. Dry the liferaft floor and inflate it
Answer: C — Get clear of the ship
The first action is to cut or release the painter and paddle clear of the sinking ship, away from suction, debris, fire and burning oil. After that, stream the sea anchor, look for survivors and give out anti-seasickness tablets.

9. A feature of an inflatable liferaft which helps keep people stationary in rough weather is ____.

  • A. Lashings on the floor of the raft for the occupants' feet
  • B. Straps from the overhead
  • C. Lifelines on the inside of the raft
  • D. Ridges in the floor of the raft
Answer: C — Lifelines on the inside of the raft
LSA Code 4.2.2 requires inflatable liferafts to have lifelines fitted around the inside of the raft. Occupants hold on to these so they stay in place and the raft stays trimmed in heavy weather.

10. The maximum speed of lowering for a lifeboat on gravity davits is controlled by the ____.

  • A. Limit switches
  • B. Emergency disconnect switch
  • C. Governor brake
  • D. Position of the counterweight on the brake handle
Answer: C — Governor brake
The centrifugal governor brake in the davit winch automatically limits the speed at which the boat lowers under gravity. LSA Code 6.1.2 sets limits on lowering speed for survival craft.

11. Immediately after abandoning a vessel, lookouts should be posted aboard liferafts to look for ____.

  • A. Survivors in the water
  • B. Food and water
  • C. Land
  • D. Bad weather
Answer: A — Survivors in the water
One of the first actions after getting clear of the ship is to post lookouts and search for survivors in the water. People in the water are recovered first, while they are still close and before hypothermia sets in.

12. The purpose of the four water pockets, located on the underside at each corner of the raft, is to ____.

  • A. Stow rainwater so that it will not take up valuable space
  • B. Act as stabilisers by filling with sea water as soon as the raft is inflated and upright
  • C. Hold the fresh water required by regulation to be provided in the raft when packed
  • D. Store the sea anchor and its line when not in use
Answer: B — Act as stabilisers by filling with sea water as soon as the raft is inflated and upright
Water ballast pockets fill with seawater as the upright raft inflates. The weight of water lowers the centre of gravity and resists capsizing by wind and waves, as required by LSA Code 4.2.4.

13. What is the purpose of the limit switch on gravity davits?

  • A. To cut off the power when the davits hit the track safety stops
  • B. To stop the davits from going too fast
  • C. To cut off the power when the davits are about 12 inches (30 cm) from the track safety stops
  • D. To release the boat from the falls automatically
Answer: C — To cut off the power when the davits are about 12 inches (30 cm) from the track safety stops
When hoisting, the limit switch cuts power to the winch motor just before the davit arms reach their stowed stops, about 12 inches away. The arms then finish the travel by hand and do not strike the stops under power, which avoids damage and broken falls.

14. The number of rocket parachute flares carried in a lifeboat is ____.

  • A. 3
  • B. 4
  • C. 5
  • D. 6
Answer: B — 4
LSA Code 4.4.8.11 requires each lifeboat to carry four rocket parachute flares meeting LSA Code 3.1, the same number required for liferafts in 4.1.5.1.11.

15. What is the full form of HRU?

  • A. Hydrostatic radar unit
  • B. Hydrostatic radio unit
  • C. Hydrostatic release unit
  • D. None of the above
Answer: C — Hydrostatic release unit
HRU stands for hydrostatic release unit. It releases a liferaft or float-free EPIRB automatically when the ship sinks to a depth of about 4 m, as required by LSA Code 4.1.6.3, and is tested and replaced according to the manufacturer's schedule.

16. Which of the following requirements regarding life-saving appliances does NOT correspond to present regulations?

  • A. All prescribed life-saving appliances shall be resistant to deterioration where exposed to sunlight
  • B. All prescribed life-saving appliances shall be made of non-combustible or fire-retardant material
  • C. All prescribed life-saving appliances shall be of a highly visible colour on parts where this will assist detection
  • D. All prescribed life-saving appliances shall be fitted with retro-reflective material where this will assist in detection
Answer: B — All prescribed life-saving appliances shall be made of non-combustible or fire-retardant material
LSA Code 1.2.2 requires appliances to resist deterioration in sunlight, be of highly visible colour and carry retro-reflective material where this helps detection. There is no general requirement for all appliances to be non-combustible; fire tests apply only to certain items.

17. In accordance with the present recommendations, a ship in distress should transmit the appropriate alarm signal followed by the distress call and message on one or all of the international distress frequencies, which are

  • A. 550 kHz, 2367 kHz and 121.5 MHz
  • B. 500 kHz, 2182 kHz and 156.8 MHz
  • C. 550 kHz, 2182 kHz and 121.5 MHz
  • D. 500 kHz, 2367 kHz and 243 MHz
Answer: B — 500 kHz, 2182 kHz and 156.8 MHz
The traditional international distress frequencies are 500 kHz (MF radiotelegraphy), 2182 kHz (MF radiotelephony) and 156.8 MHz (VHF Channel 16). Frequencies such as 121.5 MHz and 243 MHz are aeronautical emergency frequencies, and 550 kHz and 2367 kHz are not distress frequencies.

18. The donning time for an immersion suit is

  • A. 2 minutes
  • B. 5 minutes
  • C. 7 minutes
  • D. 9 minutes
Answer: A — 2 minutes
The LSA Code (2.3.1.1) requires that an immersion suit can be unpacked and donned without assistance within 2 minutes, taking into account any associated clothing and a lifejacket if the suit has to be worn with one.

19. A radar reflector is provided in

  • A. Lifeboats only
  • B. Liferafts only
  • C. Rescue boats only
  • D. Lifeboats, liferafts and rescue boats
Answer: D — Lifeboats, liferafts and rescue boats
Under the LSA Code, the equipment of lifeboats, liferafts and rescue boats each includes an efficient radar reflector, unless a survival craft radar transponder (SART) is stowed in the craft, so that the craft can be detected by searching ships' radar.

20. What colour light does a hand flare burn with?

  • A. Bright red
  • B. Orange
  • C. Bright white
  • D. Green
Answer: A — Bright red
The LSA Code (3.2) requires a hand flare to burn with a bright red colour, uniformly distributed, with a luminous intensity of not less than 15,000 cd for not less than 1 minute. Orange is the colour of smoke signals.

21. Which of the following is an LSA Code requirement for a lifejacket?

  • A. It can be correctly donned within 1 minute without assistance
  • B. It can be correctly donned within 2 minutes without assistance
  • C. It can be correctly donned within 5 minutes without assistance
  • D. It can be correctly donned within 10 minutes without assistance
Answer: A — It can be correctly donned within 1 minute without assistance
The LSA Code (2.2.1) requires that a person can correctly don a lifejacket within a period of 1 minute without assistance. The 2-minute donning time applies to immersion suits, not lifejackets.

22. Match the term LIFEJACKET with the most suitable answer given below

  • A. Davit launch
  • B. Whistle and SI light
  • C. Protection against cold
  • D. HRU
Answer: B — Whistle and SI light
Every lifejacket must be fitted with a whistle firmly secured by a lanyard and a lifejacket light, together with retro-reflective tape, as required by the LSA Code. Davit launch relates to boats, protection against cold to TPAs and HRU to liferafts.

23. Which of the following is/are the SOLAS requirements for buoyant smoke signals?

  • A. Emit smoke for a period of not less than 3 minutes when floating in calm water
  • B. Not emit any flame during the entire smoke emission time
  • C. Continue to emit smoke when submerged in water for a period of 10 seconds under 100 mm of water
  • D. All of the above
Answer: D — All of the above
LSA Code 3.3 requires a buoyant smoke signal to emit highly visible smoke at a uniform rate for not less than 3 minutes in calm water, not emit any flame, not be swamped in a seaway, and continue to emit smoke when submerged for 10 seconds under 100 mm of water.

24. The body loses heat about ____ times faster when immersed in cold water than in air at the same temperature.

  • A. 10
  • B. 20
  • C. 25
  • D. 36
Answer: C — 25
Water conducts heat away from the body roughly 25 times faster than air at the same temperature, which is why survivors in cold water become hypothermic so quickly and should get out of the water or reduce exposed surface area.

25. Which one of the listed statements regarding an immersion suit does NOT correspond to present regulations? The suit

  • A. is provided with arrangements to minimize or reduce free air in the legs of the suit
  • B. can be unpacked and donned without assistance within 2 minutes
  • C. has sufficient built-in buoyancy to avoid the use of a lifejacket
  • D. will cover the whole body with the exception of the face
Answer: C — has sufficient built-in buoyancy to avoid the use of a lifejacket
The LSA Code requires an immersion suit to cover the whole body except the face, to minimise free air in the legs and to be donned within 2 minutes. It does not require built-in buoyancy to replace a lifejacket; most suits are worn with a lifejacket.

26. Match the term TPA with the most suitable answer given below

  • A. Davit launch
  • B. Whistle
  • C. Protection against cold
  • D. Abandon ship
Answer: C — Protection against cold
A thermal protective aid (TPA) is a bag or suit of waterproof material with low thermal conductance, carried in survival craft to reduce convective and evaporative heat loss from a survivor and so protect against cold and hypothermia (LSA Code 2.5).

27. The burning duration of a hand flare is

  • A. 1 minute
  • B. 10 minutes
  • C. 15 minutes
  • D. 30 minutes
Answer: A — 1 minute
LSA Code 3.2 requires a hand flare to burn with a bright red colour for a period of not less than 1 minute, with a luminous intensity of not less than 15,000 cd, and to continue burning after immersion for 10 seconds under 100 mm of water.

28. Safe lifting signal - arm raised above the horizontal with thumb up means

  • A. Do not hoist, not ready
  • B. Hoist, ready
  • C. Lower the load
  • D. Emergency stop
Answer: B — Hoist, ready
In the standard helicopter hoisting signals, an arm raised above the horizontal with the thumb up indicates that the person is ready and the winch operator may hoist. Arms extended horizontally with thumbs down means do not hoist.

29. The minimum length of a rescue boat is

  • A. 3.8 metres
  • B. 8.5 metres
  • C. 5 metres
  • D. 7.3 metres
Answer: A — 3.8 metres
LSA Code 5.1.1.3 requires rescue boats to be not less than 3.8 m and not more than 8.5 m in length, and capable of carrying at least five seated persons and a person lying on a stretcher.

30. The minimum length of a lifeboat is

  • A. 3.8 metres
  • B. 8.5 metres
  • C. 5 metres
  • D. 7.3 metres
Answer: D — 7.3 metres
Under the LSA Code, a lifeboat shall normally be not less than 7.3 m in length, except where, owing to the size of the ship or for other reasons, the Administration considers carriage of such a lifeboat unreasonable or impracticable.
