Which DOT hazard class includes gases?

Which DOT hazard class includes gases?

• A. Explosives
• B. Gases
• C. Flammable Liquids
• D. Radioactive

Answer: (B)

Think about how DOT groups hazardous materials to guide packaging, labeling, and handling. Gases have their own category, simply called gases, which is Class 2. This class includes compressed gases, flammable gases, nonflammable gases, and toxic gases—any material that exists in a gaseous state during transport. It’s distinct from other categories: explosives belong to the explosives class, flammable liquids to the flammable liquids class, and radioactive materials to the radioactive class. So the correct choice is the gases class, because that is the designation for materials in gaseous form.
