Which statement is true about labeling hazardous waste containers?

• A. The label should include only the words 'hazardous waste'.
• B. The label should include the words 'hazardous waste', the full name of the contents, and the date added.
• C. Labels must be placed on the inside of the container.
• D. Labels should be removed during transport.

Answer: (B)

Labeling hazardous waste containers communicates three critical pieces of information: the hazard, what exactly is inside, and when accumulation began. The best statement includes the words “hazardous waste,” the full name of the contents, and the date the waste was added to the container. This makes the waste easy to identify at a glance, supports safe handling and storage time limits, and helps responders during an emergency. If the label lacks the full contents or the accumulation start date, or if labels are placed inside the container or removed during transport, visibility and traceability are compromised, increasing risk.
