Pollution containment apparatus for making a penetration in a ceiling or wall of a building or other structure
A pollution containment apparatus for removal of polluted material from a ceiling and/or a wall. The apparatus has a platform which can support a workperson and can be raised and lowered. A support on the platform holds a enclosure. The enclosure has gloves and a waste bag attached. A portion of the top of the enclosure can be opened and closed for access to the polluted portion of the ceiling and/or the wall. The entire completely assembled apparatus can be moved from one location to another.
1. A containment system for making a desired penetration in a portion of a building structure, wherein dust is generated in making the penetration, and for confining the dust therein, comprising a rigid transparent enclosure adapted to cover the portion of the building structure while a penetration is made therein, the rigid transparent enclosure being substantially rectangular and comprising respective side walls, front and rear end walls, and a top and bottom wall, respectively, whereby one or more tools may be housed in the rigid transparent enclosure without concern for making a tear or breach therein, at least one of the walls of the rigid transparent enclosure having a tray door therein, thereby providing access to the portion of the building structure in which a penetration is to be made, the at least one wall further having a periphery provided with a gasket for engaging the portion of the building structure surrounding the penetration therein, a HEPA vacuum means carried by one of the side walls of the rigid transparent enclosure externally thereof and having an inlet on the one side wall of the rigid transparent enclosure for filtering out the dust created during the penetration and for assuring a close fit between the gasket on the periphery of the one side wall of the enclosure and the portion of the building structure in which the penetration is to be made, a pair of gloves carried by the front wall of the enclosure, extending internally of the enclosure, and a container of de-tox material carried by the other side wall of the rigid transparent enclosure and having a hose passing through the other side wall to the interior of the rigid transparent enclosure, and wherein the enclosure is mounted on a transportable support.
2.
