What information should be included on chemical waste labeling?

• A. The chemical identity, hazards, and disposal instructions.
• B. The supplier's contact information.
• C. The batch number.
• D. The color and odor information.

Answer: (B)

Accurate chemical waste labeling must clearly communicate what the waste is, what hazards it poses, and how it should be disposed. The chemical identity tells anyone handling the waste exactly what substance it is, the hazard information communicates the risks and the protective measures needed, and the disposal instructions guide proper treatment or disposal to comply with regulations and prevent harm. Supplier contact information isn’t typically required on a waste label, and a batch number or details like color or odor don’t provide the essential safety or regulatory guidance needed for handling and disposal.
