Class 1 hazardous materials are primarily what type?

Class 1 hazardous materials are primarily what type?

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

Answer: (B)

Explosives are Class 1 because this class is defined by materials that can detonate or undergo a rapid, violent release of energy. That explosive energy is the defining hazard, which sets explosives apart from other dangerous materials. Gases belong to a different class (Class 2), flammable liquids to Class 3, and radioactive materials to Class 7, each with its own specific hazards and handling rules. In practice, recognizing Class 1 signals an explosive hazard that requires strict safety measures and isolation, rather than concerns about containment of a gas, ignition of a liquid, or radiation.
