Which Division 5.1 Packing Groups are permitted for Air Transmit?

• A. Packing Groups 1-2
• B. Packing Groups 2-3
• C. Packing Groups 3-4
• D. Packing Groups 1-3

Answer: (B)

The main idea is how the hazard level of an oxidizing substance affects its air transport suitability. Division 5.1 covers oxidizing substances that can intensify fires. When shipping by air, safety rules restrict the most hazardous materials more tightly because a release or reaction on board would be especially dangerous. For air transport, only packing groups II and III are permitted for Division 5.1; packing group I is not allowed due to the higher risk. So the option stating packing groups 2 and 3 reflects the correct, permitted range for air transit.
