Which statement correctly describes hazard placards in relation to hazard labels?

• A. Hazard placards use the same designs, colors and symbols as hazard labels, but each side measures 273 mm (10.8 in.).
• B. Hazard placards are used on non-bulk packages.
• C. Hazard placards are only used for international shipments.
• D. Hazard placards use completely different symbols than hazard labels.

Answer: (D)

Hazard placards and hazard labels communicate the same hazard information using the same pictograms, colors, and class meanings. The difference is mainly where and how large they are: placards are the large signs placed on vehicles and bulk shipments, while labels are the smaller stickers affixed to individual packages and smaller containers. So the statement that correctly describes their relationship is that placards use the same designs, colors, and symbols as labels, but are larger in size. The other options aren’t correct because placards are not limited to non-bulk packages, they aren’t used only for international shipments, and the symbols aren’t completely different from those on labels.
