Which items must appear on each package containing dangerous goods?

• A. Hazard class, emergency contact, temperature rating
• B. Destination, transit mode, lot number
• C. Net quantity only
• D. Proper shipping name, full shipper address, net quantity of dangerous goods

Answer: (D)

Packages containing dangerous goods must carry identifying information that enables safe handling, proper regulatory control, and effective emergency response. The essential items to be displayed on every package are the proper shipping name of the dangerous material, the full shipper address, and the net quantity of the dangerous goods in the package. The proper shipping name uniquely identifies what the package contains and, together with the quantity, informs responders and handlers about the hazards and required procedures. The shipper’s address provides traceability and a point of contact if there are questions or incidents. The net quantity indicates how much dangerous material is inside, which influences packaging, labeling, and transport restrictions.

Other markings like hazard class or emergency contact can be important in certain contexts, but they are not universally required on every package in the same way, and some details may appear on shipping papers or labels rather than on the package itself. Destination, transit mode, or a lot number do not constitute the mandatory package markings in the same sense, and a package marked with only the net quantity, for example, would miss the essential identification of the contents.

So the marking set that best meets the requirement is the one that includes the proper shipping name, the full shipper address, and the net quantity.
