If an X or RQ appears in the HM column of a shipper paper entry, the shipment is regulated by Hazardous Materials.

• A. Yes
• B. No
• C. Only if the material is flammable
• D. Only if the material is radioactive

Answer: (A)

When X or RQ appears in the HM column on the shipper’s paper, the shipment is governed by Hazardous Materials Regulations. The X flag shows the material is hazardous and must be handled under all hazmat rules—classification, packaging, labeling, shipping papers, training, and emergency response information. The RQ tag means the material has a reportable quantity; if the amount meets or exceeds that quantity, there are additional reporting requirements, on top of the standard hazmat regulations. So, either mark signals regulatory oversight by the HM Regulations, regardless of whether the material is flammable or radioactive.
