What should you do if you suspect a hazmat shipment has been tampered with or diverted?

• A. Continue transport and report the tampering after delivery.
• B. Inspect the shipment while moving and document any concerns.
• C. Notify authorities and the shipper, and do not continue transport until the issue is resolved.
• D. Defer to the carrier's procedures and continue.

Answer: (C)

When you suspect tampering or diversion of a hazmat shipment, the top priority is safety and proper handling. The responsible action is to stop movement, notify the authorities and the shipper, and not continue until you’re given clearance. This immediate halt prevents any potential release, exposure, or escalation while experts assess the situation. The shipper has the product specifics, packaging details, and the correct contacts, while authorities can determine the level of risk and coordinate containment or return as needed. Document what you observed, secure the area if it’s safe, and await instructions rather than proceeding. Inspecting a load while it’s moving is dangerous, and simply following routine carrier procedures without escalation could leave a serious hazard unaddressed.
