Which of the following is not a requirement for 1A Packaging?

Selecting single labeling with contents listed as not being a requirement for 1A Packaging is indeed the appropriate choice. The requirements for 1A Packaging, particularly for dangerous goods like explosives, typically emphasize rigorous standards to ensure safety during transport. This includes multiple layers of packing (such as triple packing), appropriate hazard labeling to indicate the dangerous nature of the goods, and a properly marked shipping name to clearly identify what is being transported.

The requirement for a single label with contents listed does not align with the stringent protocols established for 1A Packaging, where clarity of contents and hazard identification are instead prioritized through proper labels that match specific regulations. Therefore, the essence of packaging compliant with standards is focused on ensuring thorough safety measures, rather than merely requiring a single label.
