Before transport, outer hazardous bags and sharps containers must be labeled with which information?

• A. The transporter’s name, address, registration number, and 24-hour telephone number only
• B. The generator's name and address only
• C. The generator's name and address, unless treatment occurs at the generating facility, and outer containers must be labeled with the transporter's name, address, registration number, and 24-hour telephone number; the transporter may provide generator-specific labels such as bar codes or container numbers
• D. Bar codes only

Answer: (C)

Labeling is about identifying who produced the waste, who is transporting it, and how to reach someone in an emergency, so the shipment can be tracked and handled safely. The generator’s name and address should appear on outer bags and sharps containers (unless treatment occurs at the generating facility), confirming who produced the waste. In addition, the outer containers must bear the transporter's name and address, the transporter's registration number, and a 24-hour emergency telephone number to ensure the responsible party can be reached and the chain of custody can be verified. The transporter may supply generator-specific labels such as bar codes or container numbers to aid tracking. The other options omit essential pieces—one misses the generator's identity, another misses the transporter's identifying information, and another relies on bar codes alone without the required contact and identification details.
