Hazardous Materials (HazMat) Transport Practice Test

For non-bulk hazmat packages, markings must convey enough information to identify the material, its hazards, and who to contact. The UN/NA identification number provides a standardized code that responders can reference to know exactly what chemical is inside. The proper shipping name describes the material in text so anyone handling the package can understand what it is. The shipper or consignee name and address links the shipment to the responsible party and gives a direct contact for handling or emergencies. These three elements work together to ensure safe handling, regulatory compliance, and rapid response. If any one is missing, identification can be unclear, hazards can be misunderstood, or there may be no clear point of contact. That’s why all three are considered required markings for non-bulk shipments.
