Which of the following is NOT a purpose of perimeter barriers?

The purpose of perimeter barriers primarily revolves around security and property management. Delaying potential intrusions, directing traffic flow, and defining property boundaries are all critical functions of perimeter barriers that contribute to safety and organization within a given area.

When considering the option of preventing employee distractions, it becomes clear that this is not a primary function of perimeter barriers. Perimeter barriers are designed to protect an area and manage access in relation to security; they do not directly address internal workplace dynamics or distractions that employees might face. Rather, distractions are typically managed through workplace policies, environment design, and management practices rather than physical barriers. Thus, in this context, preventing employee distractions does not align with the fundamental purposes of perimeter barriers, making this option the correct choice.
