Which of the following is NOT one of the transportation hazard classes?

• A. Explosive
• B. Corrosive
• C. Non-Hazardous
• D. Radioactive

Answer: (C)

The option that states "Non-Hazardous" is correct because it does not align with the established transportation hazard classes. Transportation hazard classes are defined categories used to classify materials based on their specific hazards. These include the categories of Explosives, Corrosives, Radioactive materials, and several others, all of which represent materials with inherent risks that necessitate careful handling and regulation during transport.

Non-hazardous materials, by contrast, do not fall into any of the recognized hazardous categories. Therefore, they are not subject to the same stringent regulations and labeling that hazardous materials must comply with. This distinction is vital for ensuring safety and compliance with transportation regulations designed to protect public health and the environment.
