Class 7 Hazmat placards denote what materials?

Explanation:
Hazmat placards communicate the hazard class of the material being shipped. Class 7 is reserved for radioactive materials, so a placard with this designation signals that the shipment contains radioactive substances or sources. This helps responders recognize the need for caution, shielding, and specific safety procedures to limit exposure. Other categories—flammable, corrosive, and toxic—belong to different hazard classes, not Class 7, so they would be indicated by their own distinct placards.
