DOT hazard class 1 corresponds to:

DOT hazard class 1 corresponds to:

• A. Gases
• B. Flammable liquids
• C. Explosives
• D. Radioactive materials

Answer: (C)

The key idea here is understanding what DOT class numbers mean. Class 1 is reserved for explosives, the materials designed to release energy rapidly by detonation, including blasting agents and various types of explosive compounds. That’s why this option fits: explosives are the hazard category labeled as Class 1 in the DOT system, with subdivisions for different explosion characteristics. In contrast, gases fall under Class 2, flammable liquids under Class 3, and radioactive materials under Class 7, so those don’t match Class 1.
