Which division corresponds to non-flammable non-toxic gas?

• A. Gas Division 2.3
• B. Gas Division 2.1
• C. Gas Division 2.2
• D. Explosives Division 1.4

Answer: (C)

Gases classified under Class 2 are divided by how they behave hazard-wise: one group covers flammable gases, another covers gases that don’t burn and aren’t toxic, and a third covers toxic gases. The description “non-flammable non-toxic gas” fits the division that groups inert or non-reactive gases that don’t ignite and aren’t considered toxic under normal exposure. That’s Division 2.2. The other options point to different hazards: a flammable gas would be Division 2.1, a toxic gas would be Division 2.3, and explosives fall under a different class entirely (not gases). So the division that corresponds to non-flammable non-toxic gas is Division 2.2.
