Safety of Life at Sea
What this domain tests
SOLAS-based safety: life-saving appliances, musters and drills, emergency systems, enclosed space entry, alarms, LSA maintenance and the chief engineer's role in emergency organisation. Examiners favour concrete questions - number of lifebuoys, immersion suit stowage, EPIRB registration, muster list duties - and scenario questions about abandoning ship or rescuing a person from a tank.
Core rules and concepts
- Muster list and emergency organisation. Every person on board has a duty; the muster list states alarms, duties and substitutes. Emergency stations typically include bridge, engine room control, fire parties, first aid, and lifeboat preparation.
- Life-saving appliances. Lifebuoys with self-igniting lights and smoke signals, lifejackets for every person plus extras at watch stations, immersion suits where required by temperature, lifeboats and rescue boats with their release gear, and the LSA maintenance and inspection regime (weekly and monthly checks, annual and five-yearly servicing).
- Drills. Abandon ship and fire drills at the intervals required by SOLAS, plus enclosed space entry and rescue drills; each drill is recorded with date, time and remarks.
- Alarms and communication. General emergency alarm, public address, GMDSS, SART and EPIRB; know how to test and register them, and that a false alert must be cancelled through the appropriate authority.
- Enclosed space entry. Permit to enter, atmosphere test for oxygen (≥20.9% by volume normally accepted, minimum 20.9 to 21 recommended; never below 20% by volume in most procedures), hydrocarbons, H2S and CO; standby man, rescue equipment, continuous ventilation; entry only on the master's or authorised officer's permit.
- Engine room emergency systems. Emergency generator and emergency switchboard, emergency fire pump, quick-closing valves, remote stops, and the escape routes from the machinery space.
Worked example
A motorman collapses at the bottom of a double-bottom tank. Reasoning: never enter without breathing apparatus and a rescue team; the atmosphere may be oxygen-deficient or toxic. Action: raise the alarm, muster the rescue team with SCBA and harness, ventilate, test the atmosphere, recover the casualty with the tripod/hoist, administer first aid on deck, and record. The scoring answer refuses unaided entry and names the permit and testing steps.
Traps that cost marks
- Entering an enclosed space without testing, or testing only for oxygen.
- Forgetting the standby man and the communication method.
- Not recording drills with date, time and remarks.
- Confusing the emergency fire pump location requirement with the main fire pump.
- Saying an EPIRB may be tested by pressing the activation button.
