What are the two types of markings for dangerous goods?

• A. Packaging Use and Hazardous Materials Markings
• B. Package Specifications and Packaging Use
• C. Package Specifications and Shipping Labels
• D. Design Markings and Packaging Use

Answer: (B)

Two kinds of markings on dangerous goods packaging are used to ensure safety: packaging specifications and packaging use. Packaging specifications mark the packaging design and approval, showing that the container meets the required standards for containing a specific hazard and packaging group. This tells handlers and regulators that the packaging itself is capable of safely withstanding transport conditions for those goods. Packaging use markings indicate how the packaging may be used—what it’s permitted to contain, whether it’s single-use or reusable, and any limitations on its use. This helps prevent misuse and ensures the same packaging isn’t used beyond its approved purpose or lifespan. Other options mix in labels or vague terms that aren’t the two distinct marking categories used to verify packaging performance and permitted use.
