Which class does the DOT Hazard Class 2 include?

• A. Flammable liquids
• B. Nonflammable gases
• C. Corrosive materials
• D. Oxidizers

Answer: (B)

DOT Hazard Class 2 is specifically designated for gases, which are classified into three subcategories: flammable gases, nonflammable gases, and toxic gases. The choice of nonflammable gases properly represents one of the classifications under this hazard class.

Flammable liquids fall under a different class, while corrosive materials and oxidizers belong to other categories altogether. Nonflammable gases are significant in handling because they can pose different risks compared to flammable or toxic gases, particularly in terms of pressure and potential for creating an asphyxiation hazard without necessarily being flammable or toxic themselves. Understanding the distinctions within DOT Hazard Class 2 is essential for effective safety measures in storage, transport, and emergency response.
