ABSTRACT:
A portable isolation enclosure includes an open-bottomed enclosure having walls and a top portion constructed from a lightweight structural frame material with a lightweight fabric stretched thereacross to form a sealed enclosure. Windows of a transparent plastic material are mounted in the wall for viewing outside the enclosure. The lightweight materials of the enclosure allow one or more workers to lift the enclosure off of the ground and transport it from one contaminated area to another. An air filtration unit is pneumatically connected to the enclosure to impart a negative pressure within the enclosure, and to remove asbestos particles from air exhausted from the structure. A selectively closable door is provided in one wall which will permit a person to enter or exit the enclosure, and is designed to allow air to enter the enclosure, under the influence of the negative pressure. The enclosure may be moved by the workers into contact with a mobile or permanent decontamination facility, to allow the workers to exit directly into the decontamination facility.
