What are the outer packaging requirements for dangerous goods?

• A. Outer packaging must be a UN specification or equivalent capable of withstanding air transport; it should contain inner packaging and absorbent material where needed
• B. Outer packaging must be a standard grocery box with no inner packaging
• C. Outer packaging must be glass or metal containers only
• D. Outer packaging can be any container as long as it is leak-proof

Answer: (D)

Outer packaging for dangerous goods must be a UN specification package (or an equivalent that has been tested and approved) and capable of withstanding air transport. This standardized testing ensures the package can endure handling, loading, and potential impacts during flight without releasing its contents. In addition, when there is a risk of liquid leakage, inner packaging should be used inside the outer packaging along with absorbent material to capture any leaked liquid. This combination guarantees containment, protects people and the environment, and helps prevent contamination of other packages or aircraft compartments.

The other options fall short because they suggest using non-standard containers or lack the required testing and containment features. A grocery box with no inner packaging does not meet the durability and containment standards; restricting outer packaging to glass or metal only is unnecessary and not a universal requirement; and allowing any leak-proof container ignores the mandatory UN-specification testing and the need for proper packaging structure to ensure safe air transport.
