Which element comes first in the basic hazardous materials description on a shipping paper?
Correct answer: B – Identification number
Federal rules place the identification number first in the basic description. It is followed by the proper shipping name, hazard class or division, and packing group when one is assigned. These elements must appear in the required sequence without unrelated information inserted between them.
