What are areas like waiting rooms and stairways categorized as?

Waiting rooms and stairways are categorized as uncontrolled areas because they are generally accessible to the public without restrictions or the need for special permissions. These spaces do not have the same level of security measures as controlled or restricted areas. Controlled areas, for instance, would require some form of authorization or oversight, while restricted areas are even more limited, often accessible only to authorized personnel for safety or confidentiality reasons. Service areas typically refer to spaces designated for operational purposes, such as maintenance or logistics, rather than for public use. Thus, waiting rooms and stairways fall into the category of uncontrolled areas due to their open nature and public accessibility.
