Which of the following is a correct labeling instruction for hazardous waste containers?

• A. Label with the words 'hazardous waste', the hazard symbol, and the date added.
• B. Label with the words 'hazardous waste', the full name of the contents, and the date added.
• C. Label with the words 'hazardous' and 'waste' on separate lines.
• D. Label with the color of the container only.

Answer: (B)

Clear and precise labeling of hazardous waste containers communicates exactly what is inside and when it began accumulating. This makes it possible to handle the waste safely, store it for the correct amount of time, and stay in compliance with regulations. Including the words “hazardous waste” clearly signals the category, while listing the full name of the contents identifies the exact material, reducing the risk of mix-ups. Recording the date added shows when accumulation started, which is essential for tracking storage duration and complying with waste-handling timelines.

That combination—hazardous waste designation, full contents name, and accumulation date—provides the most complete, actionable information for anyone handling the container. Labels that omit the full contents name or the date, or rely only on symbols or color, don’t provide enough detail to manage the waste safely or to meet regulatory requirements.
