Abstract
A building protection system and method is provided which is responsive to the release of hazardous agents both outside and inside of a protected building. For an outside release, an array of sensors surrounding the perimeter of the building is triggered to provide and indication that an external release has occurred. These external sensors operate in real time and are set at relatively high thresholds to prevent false positives. Upon initial detection of a release in a concentration above the threshold level of a perimeter sensor, a central processor connected to receive a release signal from the sensor will shut down all external air exchanges for the building and activate an over-pressure system for the building interior to insure that contaminated external air does not enter. Exterior sampling inlets are monitored to determine if high agent concentrations exist as a confirmation of the indication given by the perimeter sensors. Should an internal attack occur in the entrance area, or other internal area of a protected building, an internal sensor system will cause the central processor to close off the affected area, and activate the over-pressure system to pressurize unaffecte…
