32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Lifeboat buoyancy requirement
- A totally enclosed lifeboat must self-right with its full complement and equipment when released from any attitude, and must have built-in buoyancy to float when flooded.
- Rescue boat minimum speed
- A rescue boat must be at least 3 metres long, capable of at least 6 knots, and carry at least five seated persons plus one stretcher position.
- Liferaft weak link strength
- The weak link connecting a liferaft to its hydrostatic release breaks at 2.2 plus or minus 0.4 kilonewtons so the raft releases from a sinking ship at depth.
- Lifeboat water and food scale
- Each lifeboat carries 3 litres of fresh water and 1 kilogram of food per person, in corrosion-resistant containers with drinking cups.
- On-load release gear function
- On-load release gear must release a lifeboat when it is loaded with its full complement and waterborne, and must be resettable without entering the water.
- Davit list and trim limits
- Gravity davits must be able to lower the lifeboat against a list of 20 degrees either way and a trim of 10 degrees, reaching the water under gravity.
- Winch brake holding capacity
- The lifeboat winch brake must hold at least 1.5 times the maximum working load, tested at 1.1 times the total mass of the boat with complement and equipment.
- Wire fall renewal interval
- Lifeboat wire falls must be renewed when deteriorated and in any case at intervals not exceeding five years; end-for-ending is allowed only if the wire is sound.
- Quarterly lifeboat launch drill
- Each lifeboat must be launched with its assigned crew and manoeuvred in the water at least once every three months to test launching and handling.
- Sea painter purpose
- The sea painter is led forward and made fast well ahead of the lifeboat so the boat is towed clear of the ship's side during lowering.
- Heavy weather lowering side
- Lower the lifeboat on the lee side with the bow into wind and sea, and use steadying lines and the sea painter to keep the boat clear of the ship.
- Bowsing-in line use
- A bowsing-in line pulls the lifeboat tight against the ship before hooking on for hoisting, preventing swinging and impact during recovery in rough seas.
- Drogue in following seas
- Streaming a drogue or sea anchor from the bow keeps a lifeboat stern-to the sea and reduces the risk of broaching in heavy following seas.
- Abandon ship authority
- Only the master can order abandon ship; the signal is verbal plus the general emergency alarm of seven short blasts and one long blast.
- Survival water ration
- In a survival craft, ration fresh water at about 0.5 litre per person per day until rescue is likely; never drink seawater, urine, or alcohol.
- Man overboard first actions
- Shout man overboard, release the lifebuoy with light and smoke, mark the position, and manoeuvre the ship to return to the person.
- Weekly lifeboat inspection
- Each week check that lifeboats, rescue boats, and launching appliances are ready for immediate use, and that the boat engine runs.
- Monthly abandon ship drill
- Every crew member must take part in at least one abandon ship drill and one fire drill each month, recorded in the official logbook.
- Liferaft servicing interval
- Inflatable liferafts must be serviced at approved stations at intervals not exceeding 12 months; the Administration may allow up to 30 months.
- Hydrostatic release renewal
- The hydrostatic release unit must be renewed or serviced at intervals not exceeding 12 months and must be marked with its expiry date.
- Rescue boat launch time
- The rescue boat must be kept ready for immediate launching and must be launched within five minutes of the order being given.
- Rescue boat crew minimum
- A rescue boat is manned by at least three persons, one of whom is a trained operator holding a certificate for rescue boat operation.
- Approaching person in water
- Approach from downwind and downsea, keep the person on the lee side, and stop the engine before recovering the person into the boat.
- Unconscious casualty recovery
- Use a rescue sling or basket to secure an unconscious person, bring them aboard horizontally, and keep them warm to limit cold-water shock.
- MAYDAY distress call
- The distress call MAYDAY is sent on VHF channel 16 or 2182 kHz, giving vessel name, position, nature of distress, and number of persons.
- EPIRB frequency and system
- An EPIRB operates on 406 MHz and transmits to the COSPAS-SARSAT satellite system; the beacon must be registered with the national authority.
- SART radar signature
- A SART operates on the 9 GHz radar band and shows twelve dots on a rescuing ship's radar, with a range of about five nautical miles.
- Parachute flare specification
- A red parachute flare must reach at least 300 metres, burn for at least 40 seconds, and be visible for at least 10 nautical miles.
- Hypothermia core temperature
- Hypothermia is a core temperature below 35 degrees Celsius, with shivering, confusion, and loss of coordination; severe cases stop shivering.
- Hypothermia first aid
- Remove wet clothing, insulate with blankets, and warm gradually; do not rub the limbs, do not give alcohol, and handle the casualty gently.
- Adult CPR ratio
- For adults give 30 chest compressions to 2 rescue breaths, compressing 5 to 6 centimetres at a rate of 100 to 120 per minute.
- Cold water immersion response
- The first minute of cold water immersion causes cold shock with gasping and hyperventilation; float and control breathing before attempting to swim.
