Which DOT hazard class is assigned to radioactive materials?

• A. Class 7: Radioactive
• B. Class 3: Flammable liquids
• C. Class 5: Oxidizers or organic peroxides
• D. Class 9: Miscellaneous

Answer: (A)

Understanding how hazardous materials are classified under the DOT regulations is being tested. Radioactive materials are placed in Class 7, which covers substances that emit ionizing radiation. This classification guides the specific packaging, labeling, and handling requirements needed to protect people and the environment during transport. The other options map to different hazard classes: flammable liquids are Class 3, oxidizers or organic peroxides are Class 5, and Miscellaneous Dangerous Goods are Class 9. Since radioactive materials are designated as Class 7, that is the correct category.
