Non-flammable, non-toxic gas shipments fall under UN class?

• A. 2.1
• B. 2.2
• C. 3
• D. 6.1

Answer: (B)

Non-flammable, non-toxic gases are categorized under UN Class 2, Division 2.2. Class 2 covers all gases, and division 2.2 identifies those that are not flammable and not toxic, such as inert gases like nitrogen, helium, or argon. This is why the correct classification is Class 2, Division 2.2. The other options point to different hazards: a flammable gas is Class 2, Division 2.1; flammable liquids are Class 3; and toxic substances (not specifically gases) are Class 6.1.
