  • Patent number: 5088511
    Abstract: A containment apparatus for confining asbestos fibers and the like floating in the air adjacent to a ceiling work area as a consequence of removing or repairing asbestos containing ceiling material. A substantially fiber-tight bag of flexible material has an open top adapted for positioning in close proximity to a friable ceiling substrate, or for fitting tightly against a stable ceiling substrate, in surrounding relation to the ceiling area to be worked upon and is supported in such position by an apparatus which in turn rests on the floor beneath the ceiling. One or more gloves of flexible material are sealed to openings in the bag, and each glove is adapted for providing protected access to the interior of the bag for the hand and arm of a user. At least a major portion of the bag is substantially transparent so that a user having one or both hands inserted in the gloves can view the area of the ceiling being worked upon from outside the bag.
