High Danger corresponds to which Packing Group?

• A. Packing Group Two
• B. Packing Group Three
• C. No Packing Group
• D. Packing Group One

Answer: (D)

Packing groups indicate how hazardous a dangerous good is and drive the packaging requirements. High danger is the most severe level, so substances rated as high danger must use the most robust packaging and the strictest handling rules; that corresponds to Packing Group One. The other groups represent progressively lower hazards: Group II for medium danger and Group III for low danger. “No Packing Group” would apply to items not considered dangerous or not assigned a packing group, which is not the case for high-danger goods. So the correct match is Packing Group One.
