Subsections 5.1 through 5.9 cover packing instructions for which classes?

• A. 1-5, 7, and 9
• B. 2-6, 8, and 9
• C. 1-6, 8, and 9
• D. 3-6, 8, and 9

Answer: (C)

Packing instructions are organized by hazard class in the IATA DGR. Subsections 5.1 through 5.9 specify packaging requirements for classes 1–6, 8, and 9, detailing what packaging is acceptable, the tests it must pass, and the labeling/documentation needed. Class 7 (radioactive materials) has separate packing instructions outside this range because it requires special containment, shielding, and regulatory controls. This is why the grouping includes 1–6, 8, and 9, and excludes class 7.
