Where are mobile devices permitted to be used within the facility?

Mobile devices are typically permitted to be used in controlled, secure areas within a facility to maintain safety and order. The correct choice indicates that mobile device usage is specifically allowed in the tower, which is often designated for control and surveillance functions. In this area, staff can effectively monitor activities within the facility while still maintaining the necessary security protocols.

Using mobile devices in secure housing units or unrestricted areas could pose risks, such as the potential for communication outside the facility or other security breaches. The control room, while essential for overseeing operations, might have restrictions on mobile device use to ensure that all focus remains on security-monitoring tasks. Thus, the tower is structured to be a secure environment where staff can communicate and coordinate without compromising the safety protocols of the facility.
