Class 7 designates which type of hazard?

Class 7 designates which type of hazard?

• A. Poisons
• B. Corrosive Liquids
• C. Flammable Solids
• D. Radioactive (Uranium)

Answer: (D)

Hazardous materials are grouped by the type of hazard they present, and Class 7 is the designation for radioactive materials. Uranium is radioactive, so it fits this category. The other options correspond to different hazard classes: poisons are toxic materials, corrosive liquids cause chemical burns, and flammable solids pose a fire risk. Recognizing that a material is radioactive guides how it must be handled, labeled, and safeguarded—often involving shielding, distance, time considerations, and radiation monitoring.
