Which Division 5.2 Packing Groups are permitted for Air Transmit?

• A. All Packing Groups
• B. Only Packing Group 2
• C. Only Packing Groups 1-2
• D. Only excepted quantities

Answer: (D)

Division 5.2 refers to organic peroxides, which can be highly unstable and pose serious hazards in flight. Because of this risk, air transport does not permit these materials to be carried under the usual packing groups. They are allowed only when shipped as excepted quantities, with the specific, strict packaging and labeling requirements that apply to that category. The idea is to limit the amount and risk so that a potential incident would be more controllable in an aircraft. That’s why the correct approach is to use excepted quantities rather than any of the standard packing groups.
