Bulk Over-the-Road Food Tanker Transport Safety and Security Guidelines posted on the US Food and Drug Administration (FDA) Web site include information for minimum tank cleaning requirements, as well as facility security.
The guidelines recommend that all tank wash facilities performing specified tank wash services for the food industry should receive third-party inspection and certification. If appropriate, the tank wash facility should be inspected and certified by federal, state and/or local authorities and/or representatives of shippers, carriers and consignees.
The security information reminds shippers, carriers, and consignees to maintain and update facility contacts (to include names, phone and fax numbers, and if applicable e-mail contacts) and all appropriate certificates (if required by federal, state and local authorities and/or by carriers, shippers and consignees).
