What is the difference between dangerous goods cargo and non-DG cargo, and what documentation is required for DG?

• A. DG and non-DG are the same; all cargo must have UN numbers
• B. Only non-DG require documentation
• C. Dangerous Goods cargo requires UN numbers, proper packaging, labeling, and segregation; documentation is required; non-DG does not require these specifics.
• D. DG cargo requires no special handling; Non-DG requires UN numbers

Answer: (C)

Understanding how dangerous goods differ from regular cargo and what must accompany DG shipments helps keep people safe and shipments compliant. Dangerous goods are items that can pose risks to health, safety, property, or the environment during transport. To manage these risks, regulations require assigning a UN number to identify the substance, using packaging that meets approved packing instructions, applying proper labeling with hazard marks, and ensuring segregation from other goods to prevent dangerous interactions.

Documentation is also required for dangerous goods. A shipper’s dangerous goods declaration (or equivalent DG paperwork) accompanies the shipment and confirms the UN number, the proper shipping name, the hazard class, the packing group, the quantity, and that the packaging and handling meet the applicable regulations. Non-dangerous goods do not require these specific DG details, so they don’t need UN numbers, hazard labeling, or DG documentation.

Alternative statements fail because they either treat dangerous and non-dangerous cargo as the same, claim that only non-DG needs documentation, or say that DG cargo requires no special handling. The correct concept is that DG shipments involve UN numbers, proper packaging, labeling, segregation, and mandatory DG documentation, while non-DG cargo does not.
