Final answer:
If the DD Form 250 or contractor delivery ticket is not available upon arrival of a fuel tank truck and prior to fuel receipt, the supplier or contractor should be contacted. The receiving department or unit may also need to be contacted.
Step-by-step explanation:
If the DD Form 250, Material Inspection and Receiving Report, or contractor delivery ticket is not available upon arrival of a fuel tank truck and prior to fuel receipt, the appropriate person to contact would be the supplier or contractor who is responsible for delivering the fuel. They would be able to provide the necessary documentation or assist in resolving any issues with the missing paperwork.
In some cases, it may also be necessary to contact the receiving department or unit responsible for accepting the fuel delivery. They may have additional procedures in place for handling situations where the required forms are not present.
