Are Division 6.1 hazards permitted?

• A. No, Division 6.1 hazards are prohibited
• B. Yes but only packing groups 1 in unlimited quantities
• C. Yes but only packing groups 2-3 in limited quantities
• D. Yes, with no restrictions

Answer: (C)

Division 6.1 hazards are toxic substances, and air transport treats these materials with strict limits due to their potential harm. For safety, only packing groups II and III are permitted, and they must be shipped in Limited Quantities. Highly toxic substances (packing group I) are not allowed for air transport under standard rules, and shipments in unlimited quantities aren’t permitted either. So the correct understanding is that Division 6.1 hazards may be shipped only in limited quantities and only in packing groups II or III.
