What is the difference between hazard labels and markings on a DG package?

• A. Labels convey shipping cost; markings convey destination
• B. Labels indicate hazard class; markings show UN number only
• C. Labels indicate hazard class; markings include UN number and proper shipping name, quantity, and packaging type
• D. Labels and markings are the same thing

Answer: (C)

Different kinds of information on a DG package serve separate purposes: hazard labels give instant risk cues, while markings provide precise identification and handling details needed for regulation and logistics. The hazard label is the pictorial symbol attached to the package that shows the hazard class or division at a glance. Its purpose is quick recognition by handlers, so they can apply the right protective measures, storage separation, and fire-control actions without needing to read any text. Markings are the text elements on the package that supply exact identification. They include the UN number, the proper shipping name, the hazard class/division, the packing group if applicable, and the net quantity or packaging type. These details support regulatory compliance, accurate documentation, and clear communication with carriers and emergency responders. For example, a package might bear a hazard label indicating a flammable liquid. The markings would specify UN number and proper shipping name (for instance, UN1090 Acetone), the packaging group, and the quantity and packaging type. This combination lets responders know both what the material is and how much of it is packaged, along with how it’s packed. Therefore, the statement is the best because it correctly differentiates the quick-recognition role of labels from the detailed identifying and quantitative information provided by markings. The other descriptions don’t accurately reflect these distinct purposes: labels don’t convey cost or destination, markings include more than a UN number, and labels and markings are not the same thing.
