When launching a lifeboat, when should frapping lines be rigged?

  1. Before the boat is moved from the davits
  2. Before the gripes are released
  3. When the boat is at the embarkation deck ✓
  4. Only after the boat is in the water

A motor lifeboat shall carry sufficient fuel to operate continuously for a period of which duration?

  1. 12 hours
  2. 18 hours
  3. 24 hours ✓
  4. 36 hours

What is the purpose of the hydrostatic release on an inflatable liferaft?

  1. To test the rafts hydrostatically
  2. To release the raft from the cradle automatically as the ship sinks ✓
  3. To inflate the raft automatically
  4. None of the above

Why: If the ship sinks before the raft can be launched, water pressure (typically around 10-15 feet) trips the hydrostatic release, freeing the raft container from its cradle so it floats up; the painter then triggers inflation.

Which action should be taken once fueling has been completed?

  1. Open the fuel line and drain a small amount of gasoline into the bilge to clear the line of sediment
  2. The engine should be started immediately to prevent vapor lock in the fuel line
  3. The fuel tank fill pipe should be left open to allow vapors to vent from the tank
  4. All hatches should be opened, and all compartments should be ventilated ✓

Why: After fueling, gasoline vapors may have accumulated below. Opening hatches and ventilating all compartments (and running the blower) before starting the engine removes explosive vapors. Never start the engine first.

What statement about immersion suits is TRUE?

  1. Immersion suits should be worn while performing routine work on deck.
  2. During the annual maintenance, the front zipper should be lubricated using light machine oil or mineral oil.
  3. No stowage container for immersion suits may be capable of being locked. ✓
  4. Any tear or leak will render the suit unserviceable and it must be replaced.

Why: Survival equipment must be instantly accessible, so stowage containers for immersion suits may not be capable of being locked. Zippers are waxed (not oiled), and minor tears are repairable.

You abandoned ship in the North Atlantic and one of the crew members is hypothermic. During a SAR helicopter extraction which lifting device should be avoided when hoisting this patient to the aircraft?

  1. The rescue litter
  2. The rescue basket
  3. The rescue net
  4. The rescue sling ✓

If an inflatable liferaft inflates upside down, you can right it by taking which action?

  1. Getting at least three or four men to push down on the side containing the CO2 cylinder
  2. Standing on the CO2 bottle, holding the bottom straps, and throwing your weight backwards ✓
  3. Pushing up on one side of the raft
  4. doing nothing; it will right itself after the canopy supports inflate
