What class is designated for radioactive materials?

The correct designation for radioactive materials is Class 7. This classification is part of the United Nations Recommendations on the Transport of Dangerous Goods, which categorizes hazardous substances for transport and handling. Class 7 specifically pertains to radioactive materials, including those that are fissile or have radioactive properties that can pose risks to health and safety during transport.

Understanding this classification is crucial for Hazmat technicians as it establishes specific handling, packaging, and transport requirements to ensure safety and compliance with regulatory standards. Knowledge of these classes helps in properly identifying and managing materials in emergency situations, thereby minimizing the risk of exposure or accidents involving radioactive substances.
