What is the requirement for individuals in a Security Identification Display Area (SIDA)?

The requirement for individuals in a Security Identification Display Area (SIDA) is that they are required to wear an airport-issued identification medium. This is essential for enhancing security protocols within airports, as it allows for the identification of personnel who are authorized to access sensitive areas. The airport-issued identification serves as a visible indicator that the person has undergone the necessary background checks and training to work or operate in restricted zones. This helps ensure that only authorized individuals can access secure areas, thereby maintaining a higher level of safety and security at the airport.

In the context of the other options, carrying a personal identification document is important, but it is not sufficient on its own; the individual must display the airport-issued identification medium. Remaining in designated waiting areas is not a specific requirement for access to SIDA, nor is avoiding contact with security personnel either advisable or required. Instead, interactions with security personnel can be crucial for clarifying procedures and ensuring compliance with safety regulations.
