Your examiner hands you a Class 2.2 dangerous goods entry and asks: "What placard would you expect to see on this package or container, and where would you confirm it?"

A. Class 2.2 (non-flammable, non-toxic gas) uses a green diamond placard/label; you would confirm the exact design and required markings (UN number, proper shipping name where required) using IMDG Code Volume 1, which sets out the class label diagrams and placarding requirements.

B. Class 2.2 uses the same red flammable-gas placard as Class 2.1, since both are gas classes.

C. Placard design is at the carrier's discretion and is not standardised by the IMDG Code.

D. Volume 2 of the IMDG Code contains the placard diagrams; Volume 1 contains only the dangerous goods list.

A. Nine classes: 1 Explosives, 2 Gases (2.1 flammable, 2.2 non-flammable non-toxic, 2.3 toxic), 3 Flammable liquids, 4 Flammable solids/substances liable to spontaneous combustion/substances dangerous when wet, 5 Oxidising substances and organic peroxides, 6 Toxic and infectious substances, 7 Radioactive material, 8 Corrosives, 9 Miscellaneous dangerous substances and articles.

B. Eight classes, ending at Class 8 (Corrosives) — there is no Class 9.

C. Six classes, mirroring the IMSBC Code's Group A/B/C cargo classification.

D. The IMDG Code does not classify goods into numbered classes; classification is done solely by UN number with no class system.

A. The IMDG Code segregation table uses terms including "Away from," "Separated from," "Separated by a complete compartment or hold from," and "Separated longitudinally by an intervening complete compartment or hold from" — each representing an increasing physical/spatial separation requirement between incompatible classes, applied via the segregation table cross-referencing hazard classes against each other.

B. IMDG segregation has only one category: "stow apart," with no graduated levels of separation.

C. Segregation categories apply only to Class 1 (Explosives); other classes have no segregation requirement between each other.

D. Segregation terms describe segregation from crew accommodation only, not between different cargo classes.
