6.1 Site Location and Layout

Because air-blast pressures decrease rapidly with distance, one of the most effective means of protecting assets is to increase the distance between a potential bomb and the assets to be protected. The best way to do this is to provide a continuous line of security along the perimeter of the facility to protect it from unscreened vehicles and to keep all vehicles as far away from critical assets as possible.

This section discusses the perimeter and the approach to the building. For discussion about building shape and placement on the site, see Section 6.2, Architectural.
