Physical security barriers are one of the first lines of defence against hostile threats. As an SCR operator, you must understand how barriers protect people and property, how to identify weak points, and how barriers fit into wider emergency response plans. This module introduces the types of barriers commonly used across UK sites, explains how to assess vulnerabilities, and shows how security measures connect directly to control room operations.
