Your examiner asks: "A drum in a container is marked with the Marine Pollutant mark. What obligations does this create that a non-marine-pollutant package of the same IMDG class would not have?"

A. It triggers Annex III/IMDG-specific documentation (the dangerous goods declaration must identify it as a marine pollutant), additional segregation considerations from the ship's side discharge/drainage where relevant, and pollution-incident reporting obligations if the package is lost or damaged overboard — separate from, and in addition to, whatever primary hazard class (flammable, corrosive, etc.) governs its stowage and segregation.

B. The Marine Pollutant mark has no additional legal effect beyond the primary hazard class label; it is purely informational.

C. Marine Pollutant marking exempts the package from IMDG segregation rules, since pollution risk is treated as lower priority than fire/explosion risk.

D. Marine Pollutant marking applies only to Class 9 (Miscellaneous) substances; other classes cannot carry this additional mark.

A. Annex II regulates the carriage of noxious liquid substances in bulk and categorises them by hazard to marine resources/human health as Category X (major hazard, discharge prohibited), Y (hazard, discharge restricted by concentration/distance/speed), Z (minor hazard, less restrictive limits) and OS (Other Substances, evaluated as presenting no hazard, outside the Category X/Y/Z scheme).

B. Annex II only applies to crude oil carried in chemical tankers and uses the same Category A/B/C/D scheme as IMSBC.

C. Annex II categorises substances solely by flashpoint, with no relevance to discharge or tank-washing procedures.

D. Annex II applies only to substances also listed under the IMDG Code; substances not in IMDG are unregulated under Annex II.

A. A mandatory record, analogous to the Oil Record Book, of every cargo and tank-cleaning operation involving noxious liquid substances — loading, internal transfer, unloading, tank washing/prewash, slop disposal, and discharge of residues — with dates, positions, quantities and the substance's category, retained for inspection by PSC.

B. A voluntary commercial log used only to record freight rates and demurrage, with no MARPOL legal status.

C. The Cargo Record Book is required only for Category X substances; Y, Z and OS cargoes have no equivalent recording obligation.

D. The Cargo Record Book replaces the IOPP Certificate for chemical tankers and removes the need for an Oil Record Book.
