Marine Safety, Pollution Prevention and Environmental Protection
Core concepts
Know the SOLAS, MARPOL, STCW, and MLC frameworks and their main requirements. Understand fire theory: the fire triangle, classes of fire, extinguishing methods, fixed firefighting systems, portable extinguishers, fire detection, and muster drills. Study life-saving appliances, abandon-ship procedures, survival craft, and personal survival techniques. Learn pollution prevention: oil record book, garbage management plan, sewage and air pollution controls, ballast water management, and the meaning of special areas under MARPOL Annexes I–VI. Understand risk assessment, permit-to-work systems, enclosed space entry, and personal protective equipment.
Common traps
Questions often confuse fire classes and the wrong extinguishing medium. Watch for the oil record book being described as required for all vessels regardless of size. Enclosed space entry requires atmosphere testing and a permit; never rely on smell. Remember that MARPOL Annex I covers oil, Annex II noxious liquid substances, Annex III harmful substances in packaged form, Annex IV sewage, Annex V garbage, and Annex VI air pollution.
Worked example
A fire in a galley deep-fat fryer is a Class F (or Class K) fire. Water must not be used because it causes violent boil-over; a wet chemical extinguisher or fire blanket is correct. Rule of thumb: match the extinguishing agent to the fire class and never use water on burning oil.
Study approach
Memorise MARPOL annexes and fire classes, and practise drill scenarios. Link safety procedures to real shipboard operations.
