Marking labeling1 of 2
The answer
Answer: B. If the label will not fit, the shipper may put it on a tag securely attached to the package. Round stickers with the carrier's name, barcodes and plates with the shipper's address do not warn of a hazard, whereas diamond-shaped hazard labels show the class at a glance.

Marking labeling2 of 2
The answer
Answer: B. An identification number may identify more than one chemical, and it is preceded by NA or UN. A seven-digit shipper code, a letter pair for the class and a package weight are not what an identification number is, since it is a four-digit code with a UN or NA prefix that responders look up.
