If a hazmat label, packaging, and shipping paper do not match, what should you do?

• A. Transport with caution and try to resolve en route.
• B. Do not transport; correct the mismatch by contacting the shipper.
• C. Replace the label yourself and proceed.
• D. Ignore the mismatch and ship.

Answer: (B)

Consistency among hazmat labeling, packaging, and shipping papers is essential for safe and compliant transport. The labeling tells handlers and emergency responders what hazard is present, the packaging must be appropriate for that hazard, and the shipping papers must accurately describe the shipment. When these don’t align, you don’t have reliable information to guide handling, routing, or emergency actions, which can lead to wrong PPE, wrong containment measures, or incorrect response in the event of an incident. Because of that, the correct action is not to transport and instead stop and contact the shipper to correct the mismatch before moving the load.

Don’t try to fix labels yourself or proceed with the shipment; you must involve the shipper (or supervisor) to correct the labeling, packaging, and shipping papers. Transporting with a mismatch is a regulatory violation and a serious safety risk. It’s also inappropriate to attempt to resolve the issue en route or ignore the mismatch and ship. If you’re unsure or encounter a potential hazard, secure the load and seek guidance from your dispatcher or hazmat supervisor after contacting the shipper.
