Cargo Operations Sea Year Practice Exam

Hazardous cargo is organized into classes, with a catch-all category for items that don’t fit the other definitions. The “miscellaneous dangerous goods” category is Class 9, used for a wide variety of items that pose danger but aren’t covered by the specific classes. That’s why this option is correct: it represents the miscellaneous category. Gases belong to Class 2, biohazards (infectious substances) are Class 6, and radioactive materials are Class 7, so they are not the miscellaneous category.
