Which items must be included on a hazardous waste container label?

• A. The words 'hazardous waste', the hazard symbol, and the date added.
• B. The words 'hazardous waste', the full name of the contents, and the date added.
• C. The storage room number, the hazard level, and the date added.
• D. The full name of the contents only.

Answer: (B)

Labeling hazardous waste containers focuses on clearly identifying what the waste is and when it started accumulating. The essential items are: explicitly marking the waste as hazardous waste, providing the full name of the contents so you know the exact waste stream, and recording the date the waste was first added to the container. This date establishes the accumulation start and helps ensure you stay within regulatory storage time limits while enabling safe handling and proper disposal. The hazard symbol, while useful for quick warning, is not the core requirement here, and storage room number or hazard level aren’t needed on the label. A label that only has the contents name lacks the explicit category and the timing information necessary for safe and compliant management.
