Differentiate between inner and outer packaging in DG shipments.

Differentiate between inner and outer packaging in DG shipments.

• A. Inner packaging contains the dangerous goods; outer packaging provides the protective strength and barrier to leakage during transport
• B. Inner packaging is decorative; outer packaging holds the label
• C. Outer packaging contains the dangerous goods; inner packaging protects from leakage
• D. There is no difference; both perform same function

Answer: (A)

In DG shipments, packaging serves two distinct roles: the inner packaging is the primary containment that actually holds the dangerous goods, while the outer packaging surrounds the inner container to provide mechanical protection and an additional barrier against leakage during transport. The inner packaging must be designed to be leak-tight (especially for liquids), securely closed, and made of materials compatible with the contents. The outer packaging then adds strength and cushioning, so it can withstand handling, stacking, and potential impacts, and it helps contain any leakage if the inner container were compromised. Together, they ensure that even if the inner container leaks, the outer layer minimizes spills and protects people and the environment, while also giving a sturdy shell for transport, labeling, and documentation. So the statement that best describes this is that the inner packaging contains the dangerous goods, and the outer packaging provides the protective strength and a barrier to leakage during transport. The other descriptions don’t fit because the inner packaging isn’t decorative and the outer packaging isn’t the container that holds the goods, and there is a definite difference in their roles.
