Radioactive Materials are classified under which hazard class?

• A. Class 2 Hazards
• B. Class 7 Hazards
• C. Class 8 Hazards
• D. Class 3 Hazards

Answer: (B)

Radioactive materials are treated as a separate hazard type because their danger comes from ionizing radiation, not from chemical reactivity. In the hazmat classification system, materials are grouped into classes, and Class 7 is specifically designated for radioactive materials. That’s why identifying the substance as Class 7 Hazards is the correct choice. Handling and shipping radioactive materials also require special labeling, packaging, and safety procedures tied to Class 7, reflecting the unique radiological risk. Other listed classes cover different hazards—Class 3 is flammable liquids, Class 2 is gases, and Class 8 is corrosives—so they don’t apply to radioactivity.
