ABSTRACT:
A deployable flexible walled enclosure for housing people in the event of a serious air quality degradation is provided. A pressurized enclosure, either stored in a permanent location or transportable to a selected site, includes an air supply system for filtering and subsequently supplying clean air to the interior of the enclosure. The structure is compactly packaged when not in use and is capable of being deployable and/or activated from a remote control station in time of need. A small cache of life support elements are stored in the predeployed enclosure for use as needed upon deployment.
