Which Hazard Class Covers Radioactive Materials?

• A. Class 6 Hazards
• B. Class 7 Hazards
• C. Class 8 Hazards
• D. Class 2 Hazards

Answer: (B)

Radioactive materials are assigned to Class 7 Hazards because they involve ionizing radiation that requires specialized handling, packaging, and labeling. In the hazmat classification system used for transport, there are nine classes, each covering a different type of hazard. Class 7 is specifically reserved for radioactive materials, reflecting the unique risks and regulatory requirements surrounding radioactivity, such as exposure limits, shielding, and specialized placards and documentation. This distinction helps responders and transport personnel recognize the appropriate precautions. For comparison, other classes cover different hazards—gases, corrosives, or toxic substances—so placing radioactive materials in Class 7 keeps the regulatory framework clear and enforceable.
