Which hazard class includes nonflammable gases?

• A. Flammable solids
• B. Nonflammable gases
• C. Poison liquid
• D. Corrosive poisons

Answer: (B)

Nonflammable gases are categorized under the Gases hazard class. In hazmat classification, gases are grouped as Class 2 and are subdivided based on risk type: flammable gases, nonflammable gases, and toxic gases. Nonflammable gases, by definition, do not burn, so they fall into the nonflammable gases subdivision of the Gases class. That makes the concept clear: the relevant hazard class is Gases, with nonflammable gases as the specific subdivision. The other options point to different hazard classes (solids that burn, toxic liquids, corrosive poisons) and do not represent the gas category.
