Division 2.1 refers to which type of material?

• A. Nonflammable gas under pressure
• B. Cryogenic argons with high pressure
• C. Flammable gas at elevated pressure
• D. Nonpoisonous gas at room temperature

Answer: (C)

Flammable gases are classified as Division 2.1. This category covers gases that will ignite or burn readily when released, including those stored under pressure. So describing the material as a flammable gas at elevated pressure lines up with Division 2.1, which is why it’s the correct choice. The other options refer to nonflammable gases, cryogenic conditions, or nonpoisonous gases at room temperature, none of which describe a flammable gas in Division 2.1.
