An inside clear zone should be how many feet?

The inside clear zone, which is crucial in maintaining security and ensuring an unrestricted area within a facility, is properly designated at 30 feet. This distance is established to prevent unauthorized access and allow for safe surveillance and response to potential intruders. By maintaining this 30-foot space, security personnel can better monitor activities and respond effectively without obstruction or interference. This measurement ensures that there is adequate space for movement and visibility, thereby enhancing the overall security posture.

The other options, while they may seem reasonable, do not align with the established standards necessary for effective security management. A 30-foot clear zone balances safety and practicality, enabling officers to perform their duties effectively while minimizing risks associated with proximity to secured areas.
