From the Introduction to Planning Guidance: "Our Nation's federal departments and agencies are entrusted with providing safe and secure environments for our government's essential functions and assets, including the personnel and public who may occupy or conduct business at these facilities. Leaders must plan for emergencies at federal facilities that range from active shooter incidents, hostage situations, and similar security challenges to natural threats, which include fires, tornadoes, floods, hurricanes, earthquakes, and pandemics. [...] This document provides Facility Security Committee (FSC) members, emergency planners, disaster committees, executive leadership, and others involved in emergency preparedness, response, recovery and operations planning with detailed discussions of unique issues federal facilities face before, during, and after active shooter incidents. As our Nation continues to draw on lessons learned from active shooter incidents, leaders should incorporate those lessons learned into existing or newly created plans and procedures."
