What is the purpose of the Barrier Plan within an AT Plan?

The purpose of the Barrier Plan within an AT (Antiterrorism) Plan is to specify the location, configuration, and operational procedures for physical barriers. This plan is crucial as it addresses the implementation of protective measures designed to deter or mitigate threats and ensure the safety of personnel and assets.

By detailing the specifics of where barriers are placed and how they are intended to function, the Barrier Plan helps in creating a structured environment where access can be controlled. This is vital in high-security settings where physical barriers can prevent unauthorized access and contribute to overall security effectiveness.

The other options, while related to security and emergency procedures, do not directly pertain to the specific role of the Barrier Plan in detailing physical barriers. Evacuation procedures, communication methods during emergencies, and personnel responsibilities are essential components of the broader AT Plan but fall outside the specific scope of the Barrier Plan itself.
