What information should be included on a hazardous waste container label?

• A. Contents and date
• B. Size of container
• C. Company name
• D. Color of label

Answer: (A)

Labels on hazardous waste containers must clearly state what waste is inside and when it was placed in the container. Knowing the contents tells you the specific hazards present and guides safe handling, storage, and disposal. The date gives the accumulation start time, helping track how long the waste has been stored and ensuring compliance with regulatory storage time limits. Together, this information supports proper segregation, compatibility checks, timely disposal, and informs emergency responders about what’s inside and how urgent actions should be taken.

The size of the container doesn’t convey hazard information or storage timing, so it’s not a primary label detail. A company name is useful for contact and custody records but isn’t necessary for identifying the waste or its hazards on the label. The color of the label doesn’t provide reliable information about contents or age, so it’s not a meaningful labeling element.
