How is a hazardous material defined for Class 314 purposes?

• A. Only radioactive or explosive materials
• B. Materials only dangerous to the environment
• C. Substances that pose health or safety risks to workers or the public, including chemicals and infectious agents, as defined by applicable regulations
• D. Any material classified as hazardous by a national standard

Answer: (C)

Class 314 defines a hazardous material by the actual risk it poses to health or safety, as determined by the applicable regulations. This means the focus is on potential harm to workers or the public, not solely on environmental impact or on a general label of “hazardous.” Materials that can threaten health or safety—such as toxic chemicals, flammable substances, reactive materials, or infectious agents—fall under this definition when regulatory definitions classify them as hazardous. The key is that the determination comes from the regulations that govern handling, labeling, and safety procedures, not from a single characteristic or a generic national standard. So, the best choice reflects that risk-based, regulation-driven approach: substances posing health or safety risks to people, including chemicals and infectious agents, as defined by applicable regulations.
