DOT Hazard Class 1 includes which type of material?

• A. Flammable solids
• B. Explosives
• C. Corrosives
• D. Nonflammable gases

Answer: (B)

Class 1 is defined by the presence of an explosive hazard—the material is capable of detonation or a high-order rapid release of energy that produces a blast, shock wave, heat, and high pressure. This makes explosives distinct from other hazards: flammable solids (which burn rapidly but don’t detonate), corrosives (which cause chemical burns and damage), and nonflammable gases or other gases that may be hazardous but don’t inherently detonate. Therefore, the type of material included in Class 1 is explosives, such as dynamite or TNT, which require special handling and regulatory controls because of the explosive energy they can unleash.
