Be sure the turnout is large enough to handle the volume and size of traffic. A wooden deck or platform at, or slightly higher than, the level of the truck bed hastens checking. It makes it easier to see the cargo. The platform should be as long as the vehicles being used. Cargo is less likely to be diverted if you keep a close watch on cargo documentation and container safety.
Containerized cargo is less likely to be stolen or sabotaged.
But you must watch closely as containers are filled and sealed for storage or shipment. Cargo can be pilfered before the seal is applied. An unsealed container can be moved to a stacking area. Or someone may apply a false seal, break the seal later, remove cargo, and then apply a legitimate seal. Look for signs of damage or unserviceability.
