Broken Seal and Suspicious Questions at the Truck Stop
At 0200 at a truck stop outside Brunswick, you return to your tractor-trailer after a 15-minute break. You are carrying 12 one-ton cylinders of UN1017, chlorine, 2.3. The trailer is placarded TOXIC and INHALATION HAZARD. You find the trailer door seal cut and hanging from the latch. A person in a hooded jacket is standing near the rear doors and asks, 'What are you hauling? Is it something good?' Your shipping papers are in a folder on the passenger seat and the truck is unlocked. The person does not display a company ID and does not work at the truck stop. There is no security guard on duty. It is dark, the lot is nearly empty, and your cell phone has a weak signal.
1. What should you do first, and what should you not do?

Treat the cut seal and the stranger as a possible security incident, not a customer-service problem. Do not confront the person, do not open the trailer, do not confirm or discuss the chlorine cargo, and do not hand over shipping papers. Move to a safe, well-lit area if you can do so without passing close to the person; otherwise stay in the locked cab and call 911. Tell the dispatcher and the company security contact that the seal is broken and the trailer may have been tampered with. Keep the shipping papers secured. Do not move the vehicle until law enforcement or a qualified company representative inspects the load and verifies the seal number against the shipping papers.
2. How does security awareness apply to this chlorine load, and when may you resume the trip?
Read the worked answer
Chlorine is a toxic inhalation hazard and a theft or terrorism target. Unauthorized access, suspicious questions, and a broken seal are exactly the behaviors security awareness training tells drivers to report. Follow the carrier's security plan: restrict information to those with a need to know, verify seals and locks, park in secure areas, and report suspicious activity to local law enforcement and the company. If inspection shows a missing cylinder, a leaking container, or evidence of tampering, treat it as a hazmat emergency and call 911 and the NRC as appropriate. A truck stop with no guard is not adequate security for this load. Do not resume the trip just because the person walks away; resume only after the load is inspected and cleared.
