Which of the following is required on a hazmat shipping paper?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

The proper shipping name, hazard class, UN/NA identification number, packing group, and total quantity

  1. A The proper shipping name, hazard class, UN/NA identification number, packing group, and total quantity
  2. B The driver's social security number
  3. C Only the shipper's phone number
  4. D Only the destination address

Why this is the answer

Hazmat shipping papers must include, for each material: (1) the proper shipping name (the official name in the Hazardous Materials Table, like 'Gasoline'); (2) the hazard class (such as '3' for flammable liquid); (3) the UN/NA identification number (such as 'UN1203'); (4) the packing group (I, II, or III, indicating severity within the class); and (5) the total quantity by weight or volume. The information must appear in a standard order, often abbreviated 'NHIPS' (Name, Hazard class, ID number, Packing group, Subsidiary). An emergency response phone number — monitored 24/7 by someone who can speak about the materials — must also appear on or with the shipping papers. The shipper certifies the accuracy of the description; the driver verifies it matches what is being loaded.
