Any mail sack or package found on the ramp area should be turned into whom?

The appropriate action when encountering any mail sack or package on the ramp area is to turn it into the Airport Police Duty Officers. This is because the airport police are responsible for security and safety at the airport, and they are trained to handle potentially suspicious items in a manner that ensures the safety of all personnel and passengers.

By routing such discoveries to the airport police, you ensure that trained authorities can properly assess the situation, determine whether the item poses any threats, and take necessary actions as required by airport protocol. This chain of custody is critical for maintaining security in restricted areas, where unauthorized personnel are not permitted.

Other choices, such as the Airport Maintenance Crew or security personnel at the main terminal, may not have the specific training or authority to deal with potentially sensitive or dangerous items, which highlights the importance of involving the proper authorities for hazardous situations.
