Which statement correctly differentiates hazard labels, placards, and markings?

• A. Labels identify hazard on individual packages; placards identify hazard of the entire load on vehicles/containers; markings include UN/ID numbers and shipping names.
• B. Labels identify the entire load; placards identify hazard on individual packages; markings include weight only.
• C. Markings identify UN/ID numbers only; labels and placards convey no hazard information.
• D. Placards identify hazard on individual packages; labels identify UN/ID numbers.

Answer: (A)

The main idea here is understanding what each hazard communication element conveys and where it applies. Hazard labels stay with individual packages and show the specific hazard of that package (the class/division, and often pictograms). Placards are placed on the transport vehicle or container to warn about the hazard of the entire load being moved. Markings appear on the outside and include the UN/ID numbers and the proper shipping name, helping anyone identify exactly what material is inside. So the correct statement aligns with how these elements function together: labels identify hazard on individual packages; placards identify hazard of the entire load on vehicles or containers; markings include UN/ID numbers and shipping names. The other descriptions mix up who communicates hazard information or what markings include (for example, assuming labels cover the whole load or that markings are limited to weight), which isn’t accurate.
