tion, and activities in the facility. Chapter 6 presents a structured approach to the design and deployment of a building protection system that is based on risk assessment and management. That chapter also proposes an analytic process that is based on currently available and proven methodologies to assess costs and benefits of a building protection system. The committee presents its conclusions and recommendations in Chapter 7.
As in any emergent situation, there is a window of operational influence following a biological or chemical attack on a building. The time during which one can make critical decisions or take actions of low or high regret may be extremely short (minutes).2 Preparation—technical and operational—can be advantageous to protecting building occupants, but at a cost. It is the committee’s hope that this report will assist DOD in making cost-benefit decisions that will maximize the window of operational influence, save lives, and maintain operational facilities at an acceptable cost. Although this study was commissioned by DTRA for the protection of military buildings, the committee’s findings and recommendations can, obviously, also be applied to nonmilitary buildings.
