Maritime Safety and Emergency Procedures

What the safety paper tests

Drill programmes, muster lists, fire fighting, abandon ship, man overboard and enclosed space entry. Questions are practical: which turn, which extinguisher, which interval, who does what.

Core rules

  • SOLAS and STCW drill intervals: abandon ship and fire drills at least monthly, with the crew mustered and the drill recorded; other emergency drills at least every three months. Every crew member must participate in at least one abandon ship and one fire drill each month.
  • Fire theory: the fire triangle of fuel, oxygen and heat, extended to a tetrahedron with the chemical chain reaction. Classes: A solid, B liquid, C gas, D metal, F cooking oil and electrical fires treated separately.
  • Fixed CO2 systems: evacuate the space, account for everyone, seal openings, then release; never release with people inside.
  • Man overboard: Williamson turn puts the vessel back on the reciprocal track when the person is lost from sight; the Anderson turn suits a manoeuvrable vessel with the person in sight.
  • Enclosed space entry: permit, atmosphere test for oxygen and hydrocarbons, continuous ventilation, standby man at the entrance and rescue equipment ready.
  • Life-saving appliances: lifeboat and liferaft capacity, immersion suits, EPIRB and SART carried and tested as required.

Worked example

A crew member falls overboard at night and is lost from sight. Hard over to starboard, then hard over the other way once the heading is about 60 degrees off the original course. That is the Williamson turn: it returns the ship along the reciprocal of her original track, which is where the person is most likely to be, and it is the right choice when the position of the casualty is uncertain.

Traps that cost marks

  • Quoting quarterly for fire drills when the requirement is monthly.
  • Using a water extinguisher on a cooking oil fire or on live electrical equipment.
  • Releasing CO2 without confirming the space is clear.
  • Choosing the Anderson turn when the person is out of sight.
