Answer Key

PST exit exam questions and answers — Set 11 — Personal Survival Techniques

Set 11 of the Personal Survival Techniques (PST) exit exam bank — 30 of 781 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 11 — 30 PST exit exam questions with answers

1. With the air supply on, the air pressure inside the survival craft will be ____.

  • A. Changing in relation to the speed of the craft
  • B. Less than outside air pressure
  • C. Greater than outside air pressure
  • D. Equal to outside air pressure
Answer: C — Greater than outside air pressure
The self-contained air support system under LSA Code 4.8 keeps the inside pressure slightly above atmospheric, never exceeding it by more than 20 mbar, so smoke and toxic gases are kept out of the closed lifeboat.

2. A marine evacuation system shall be capable of being deployed by ____.

  • A. One person
  • B. Two persons
  • C. Three persons
  • D. Four persons
Answer: A — One person
LSA Code 6.2.1 requires a marine evacuation system to be capable of deployment by one person, and the passage and platform to be ready for use so the ship can be evacuated in the required time.

3. Partially enclosed lifeboats shall be provided with permanently attached rigid covers extending over not less than ____.

  • A. 5% of the length of the lifeboat
  • B. 10% of the length of the lifeboat
  • C. 15% of the length of the lifeboat
  • D. 20% of the length of the lifeboat
Answer: D — 20% of the length of the lifeboat
LSA Code 4.5.1 requires partially enclosed lifeboats to have permanently attached rigid covers extending over not less than 20% of the length from the stem and 20% from the aftermost part, plus a foldable canopy between.

4. How much fuel is required on a lifeboat?

  • A. Sufficient fuel to run the fully loaded lifeboat at 10 knots for not less than 12 hours
  • B. Sufficient fuel to run the fully loaded lifeboat at 6 knots for not less than 24 hours
  • C. Sufficient fuel to run the fully loaded lifeboat at 5 knots for not less than 48 hours
  • D. Sufficient fuel to run a partially loaded lifeboat at 6 knots for not less than 20 hours
Answer: B — Sufficient fuel to run the fully loaded lifeboat at 6 knots for not less than 24 hours
LSA Code 4.4.6.8 requires sufficient fuel for the fully loaded lifeboat, with the engine running, to proceed at 6 knots for a period of not less than 24 hours.

5. To inflate a davit-launched liferaft you ____.

  • A. Connect the compressed air nozzle to the inflation tube
  • B. Pull the inflation lanyard
  • C. Connect the hand pump to the inflation tube and pump it up
  • D. Connect the helium nozzle to the inflation tube
Answer: B — Pull the inflation lanyard
A davit-launched liferaft is hooked onto the davit fall, swung out and inflated at the embarkation deck by pulling the inflation lanyard, which fires the CO2 cylinder. Occupants then board before it is lowered.

6. As a vessel sinks to a depth of about 4 metres (15 feet), the hydrostatic release unit frees the liferaft container from its cradle by ____.

  • A. Breaking the weak link
  • B. Releasing the tie-down strap
  • C. Pulling the operating cord
  • D. Releasing the CO2 cylinder
Answer: B — Releasing the tie-down strap
At about 4 m depth the water pressure activates the HRU, which cuts or releases the securing strap holding the container in its cradle. The container floats up, the painter pulls out and inflates the raft, then the weak link breaks.

7. When abandoning ship in an emergency by jumping into the water, you should ____.

  • A. Jump feet first from the windward side
  • B. Dive head first from the bridge
  • C. Dive head first from the main deck
  • D. Follow directly behind another person on the leeward side
Answer: A — Jump feet first from the windward side
Always jump feet first, holding the lifejacket down and covering the nose and mouth, from as low a height as possible. The windward side avoids the ship drifting down on you and keeps you clear of oil and smoke.

8. Your vessel has 3 lifeboats on each side. The aftermost boat on the port side is designated as boat number ____.

  • A. 6
  • B. 5
  • C. 3
  • D. 3 PORT
Answer: A — 6
Lifeboats are numbered from forward to aft, with odd numbers on the starboard side and even numbers on the port side. The port boats are therefore numbered 2, 4 and 6, making the aftermost port boat number 6.

9. To release the davit fall hook of a davit-launched liferaft once waterborne, you must ____.

  • A. Pull the release lanyard
  • B. Pull the hydraulic release
  • C. Push the release button
  • D. Pull on the ratchet handle
Answer: A — Pull the release lanyard
Davit-launched liferafts use an automatic release hook. Once the raft is waterborne and the weight is off the hook, the person in charge pulls the release lanyard to free the raft from the fall.

10. If more than one liferaft is manned after a vessel has been abandoned, ____.

  • A. Each raft should go in a different direction in search of land
  • B. The possibility of a search aircraft finding you is increased by spreading out
  • C. Reduce the number of rafts by getting as many people as possible into as few rafts as possible
  • D. Tie the rafts together and try to stay in a single group
Answer: D — Tie the rafts together and try to stay in a single group
Survival craft should stay together near the casualty position and be secured to each other. A group of craft presents a larger target for searchers and allows survivors and equipment to be shared.

11. Frapping lines are fitted to lifeboat davits to ____.

  • A. Reduce the swinging of the lifeboat as it is being lowered from the embarkation level
  • B. Secure the lifeboat in the davits when in the stowed position
  • C. Hold the lifeboat to the ship's side until the tricing lines are passed
  • D. Be used as a safety line in an emergency
Answer: A — Reduce the swinging of the lifeboat as it is being lowered from the embarkation level
Frapping lines are passed around the falls to steady the boat and reduce its swing as it is lowered from the embarkation deck. Tricing pennants and bowsing tackles bring the boat alongside for embarkation.

12. The light inside an inflatable liferaft is turned on ____.

  • A. Automatically as the liferaft inflates
  • B. With a switch near the boarding handle
  • C. At night because the light has a photosensitive switch
  • D. By screwing the bulb in after the raft is inflated
Answer: A — Automatically as the liferaft inflates
LSA Code 4.2.3.3 requires a manually controlled lamp inside the canopy that lights automatically when the raft is inflated, so occupants can board and find equipment in the dark.

13. The length of a rescue boat shall be not less than ____.

  • A. 3 metres
  • B. 3.8 metres
  • C. 4 metres
  • D. 5 metres
Answer: B — 3.8 metres
LSA Code 5.1.1.4 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.

14. Which item of survival craft equipment is most suitable for night signalling to a ship on the horizon?

  • A. A rocket parachute flare
  • B. A red hand flare
  • C. An orange smoke signal
  • D. A flashlight
Answer: A — A rocket parachute flare
A rocket parachute flare rises to at least 300 m and burns with a bright red light for at least 40 seconds, so it can be seen from a ship over the horizon. Hand flares are low-level and smoke is for daylight.

15. If you wish to remove an inflatable liferaft from its cradle manually, the best way to free it is by ____.

  • A. Cutting the restraining strap
  • B. Unscrewing the turnbuckle on the back of the cradle
  • C. Lifting one end of the raft
  • D. Pushing the manual release button on the hydrostatic release unit
Answer: D — Pushing the manual release button on the hydrostatic release unit
The hydrostatic release unit has a manual release. Pressing it frees the securing strap so the container can be launched by hand, without cutting straps or damaging the equipment.

16. One of the signals, other than a distress signal, that can be used by a rescue boat to attract attention is a ____.

  • A. Red star shell
  • B. Searchlight
  • C. Burning barrel
  • D. Orange smoke signal
Answer: B — Searchlight
Red star shells, flames such as a burning barrel and orange smoke are distress signals listed in COLREG Annex IV. A searchlight, required equipment in rescue boats, may be used to attract attention without signifying distress.

17. When should food and water be issued to survivors after boarding a lifeboat or liferaft?

  • A. After 12 hours
  • B. After 24 hours
  • C. After 48 hours
  • D. Some immediately and then not until 48 hours later
Answer: B — After 24 hours
Except for the injured, no water or food should be given in the first 24 hours, because the body still holds reserves and the kidneys conserve water. Rations then start at about half a litre of water per person per day.

18. The lubber's line of a magnetic compass indicates ____.

  • A. Compass north
  • B. The direction of the vessel's head
  • C. Magnetic north
  • D. A relative bearing taken with an azimuth circle
Answer: B — The direction of the vessel's head
The lubber's line is a fixed mark on the compass bowl aligned with the fore-and-aft line of the craft. The card reading against it gives the compass heading, that is, the direction of the vessel's head.

19. The capacity of a liferaft on board a vessel can be determined by ____.

  • A. Examining the Certificate of Inspection
  • B. Examining the plate on the outside of the raft container
  • C. Referring to the muster list
  • D. Referring to the ship's articles
Answer: B — Examining the plate on the outside of the raft container
LSA Code 4.2.6.3 requires the liferaft container to be marked with the maker's name, serial number, number of persons it is permitted to carry, SOLAS, type of pack and date of last service.

20. Water pockets on the underside of an inflatable liferaft are for ____.

  • A. Catching rainwater
  • B. Stability
  • C. Easy drainage
  • D. Manoeuvrability
Answer: B — Stability
Water ballast pockets under the floor fill with sea water as the raft inflates, lowering its centre of gravity and resisting wind drift and capsizing. The LSA Code requires such stabilising arrangements on inflatable liferafts.

21. In order for the automatic drain of a lifeboat to operate properly, ____.

  • A. The cap should be removed to drain the boat when it is waterborne
  • B. The cage must be kept free of rubbish or the ball may not seat properly
  • C. There must be an automatic ball check located in a siphon tube
  • D. The small lever releasing the rubber ball float must be turned anticlockwise
Answer: B — The cage must be kept free of rubbish or the ball may not seat properly
The automatic drain uses a ball inside a cage that lets water drain when the boat is out of the water and seats to seal the hole when afloat. Debris in the cage stops the ball seating, allowing sea water to flood in.

22. According to SOLAS, lifeboat falls must be renewed at intervals not exceeding how many years?

  • A. 2.5
  • B. 3
  • C. 4
  • D. 5
Answer: D — 5
SOLAS III/20.4.1 requires falls used in launching to be turned end for end at intervals not exceeding 30 months and renewed when necessary due to deterioration, or at intervals not exceeding 5 years, whichever is earlier.

23. Lifeboats shall be capable of being launched with the ship making headway at speeds up to ____.

  • A. 3 knots in calm water
  • B. 5 knots in calm water
  • C. 7 knots in calm water
  • D. 10 knots in calm water
Answer: B — 5 knots in calm water
SOLAS and the LSA Code require lifeboats on cargo ships to be capable of being launched, and of being released, with the ship making headway of up to 5 knots in calm water.

24. Your vessel has 3 lifeboats on each side. The middle boat on the starboard side is designated as boat number ____.

  • A. 2
  • B. 2 STARBOARD
  • C. 3
  • D. 4
Answer: C — 3
Lifeboats are numbered from forward, odd numbers to starboard and even numbers to port. The starboard boats are 1, 3 and 5, so the middle starboard boat is number 3.

25. What is fitted on the underside of an inflatable liferaft to help prevent it from being dragged by the wind or overturned?

  • A. Ballast bags
  • B. A keel
  • C. Righting straps
  • D. Sea anchor
Answer: A — Ballast bags
Water ballast bags under the floor fill with sea water, adding weight low down. This increases stability, reduces drift caused by wind on the canopy and resists capsizing in heavy weather.

26. All personnel on board a vessel should be familiar with the rescue boat ____.

  • A. Boarding and operating procedures
  • B. Maintenance schedules
  • C. Navigational systems
  • D. Fuel consumption rates
Answer: A — Boarding and operating procedures
Crew must know how to board and operate survival craft and rescue boats in an emergency. SOLAS III/19 requires familiarisation training and drills covering the launching and operation of rescue boats.

27. On open lifeboats, the purpose of the wire stretched between the davit heads is to ____.

  • A. Keep the movement of the davits at the same speed
  • B. Keep the davits from slipping when they are in the stowed position
  • C. Prevent vibration during lowering of the boat
  • D. Support the lifelines (manropes)
Answer: D — Support the lifelines (manropes)
The span wire rigged between the davit heads carries the manropes (lifelines) that hang down into the boat. Occupants hold them while the boat is lowered and can use them to climb out if needed.

28. A right-handed propeller will cause the survival craft to ____.

  • A. Walk the stern to starboard when going astern
  • B. Walk the stern to port when going astern
  • C. Run faster than a left-handed propeller
  • D. Right itself if capsized
Answer: B — Walk the stern to port when going astern
Because of transverse thrust, a right-handed fixed-pitch propeller turning astern rotates anticlockwise viewed from aft, walking the stern to port and swinging the bow to starboard.

29. When using the rainwater collection tubes on a liferaft, the FIRST collection should be ____.

  • A. Passed around so all can drink
  • B. Poured overboard because of salt washed off the canopy
  • C. Saved to be used at a later time
  • D. Used to boil food
Answer: B — Poured overboard because of salt washed off the canopy
The first rain washes accumulated salt spray off the canopy, so this water is salty and should be discarded. Once the canopy is rinsed clean, the following rainwater can be collected and stored for drinking.

30. On most makes of inflatable liferaft, the batteries for the light inside the raft can be made to last longer by ____.

  • A. Unscrewing the bulb during daylight
  • B. Operating the switch for the light
  • C. Taking no action, as there is no way of preserving power
  • D. Taking no action, as they shut off automatically in daylight
Answer: B — Operating the switch for the light
The interior lamp lights automatically on inflation, but LSA Code requires it to be manually controlled. Switching it off during daylight conserves the battery, which must otherwise last at least 12 hours.
