Gases in Division 2.2 are exempted from regulations. Which division does this refer to?

• A. 2.1
• B. 2.2
• C. 2.3
• D. 1.1

Answer: (B)

Gases are grouped under Class 2, with three divisions: flammable (2.1), non-flammable and non-toxic (2.2), and toxic (2.3). Division 2.2 covers non-flammable, non-toxic gases, and these are exempt from the main dangerous goods regulations because they don’t present the same hazards as the other divisions. That’s why the statement points to Division 2.2 when mentioning exemption. The other divisions involve greater risks—flammable gases, toxic gases, or explosive materials—so they remain regulated. Even though Division 2.2 is exempt from many regulatory requirements, you still handle these gases with appropriate safety precautions for pressurized containers.
