Which sequence correctly lists the general entries on shipping papers in the order presented?

• A. Proper Shipping Name; Hazard Class Number; UN or NA Identification Number; Packing Group Number (if Assigned)
• B. UN or NA Identification Number; Hazard Class Number; Packing Group Number (if Assigned); Proper Shipping Name
• C. Packing Group Number (if Assigned); Proper Shipping Name; UN or NA Identification Number; Hazard Class Number
• D. Hazard Class Number; Packing Group Number; Proper Shipping Name; UN or NA Identification Number

Answer: (A)

Understanding how shipping papers present information for hazmat shipments helps responders quickly identify the material, its hazard, and the actions needed. The correct sequence starts with the Proper Shipping Name—the formal name used in regulations and labeling, which immediately identifies what the material is. Next comes the Hazard Class Number, indicating the primary danger class (for example, flammable liquid, toxic, corrosive), guiding handling and emergency response. Then the UN or NA Identification Number, which links to the exact material in the UN/NA designation system, enabling precise cross-referencing with tables, placards, and response guides. Finally, the Packing Group Number, if assigned, shows the level of packaging risk and affects packaging and transport requirements. For example, gasoline would appear as Gasoline, Hazard Class 3, UN 1203, Packing Group II. Other sequences disrupt this logical flow by moving the UN number before the hazard class or omitting the correct packing group position, making it harder to quickly verify the shipment.
