METHOD AND APPARATUS FOR PROTECTING BUILDINGS FROM CONTAMINATION DURING CHEMICAL OR BIOLOGICAL ATTACK

摘要

Methods and systems are provided for preventing contamination of building regions or zones from unwanted chemical or biological agents during and after a chemical or biological attack. One or more inflatable occlusion devices are preferably provided for occluding or filling selected regions within a building. The occlusion devices can be inflated to, for example, help prevent the building HV AC system or corresponding duct work from delivering a chemical or biological agent from one location to another within a building. The occlusion devices can also be used to occlude or occupy entire building regions or sections, such as entire rooms, hallways, windows, doorways, etc., or parts thereof, to help protect these regions from a harmful agent during an attack, and/or to provide a protective shell over or around selected equipment.
