Portable containment device for treatment of hazardous materials

Claim 2

A disposable device adapted for receiving asbestos insulation and like hazarous materials, said disposable device comprising: a length of lay-flat tubing forming a bag, said bag being flexible and collapsible and including two sides, two side edges formed by opposed folds of said bag, said two side edges joining said two sides together, a top edge of said bag and a bottom edge of said bag, said two side edges extending substantially parallel to each other from said top edge of said bag to said bottom edge of said bag, said top edge and said bottom edge extending substantially parallel to each other and extending substantially perpendicular to said two side edges, said bottom edge being sealed to close off a bottom of said bag and said top edge having an opening for entry of said asbestos insulation and like hazardous materials into the interior of said bag, and glove means sealed to one of said two sides of said bag for protected access to the interior of said bag from the exterior of said bag.

Claim 3

A device in accordance with claim 1, wherein said glove means includes two arm holes defined by one of said two sides of said bag and a glove is attached to each of said two arm holes.

Claim 4

A device in accordance with claim 2, further comprising a tool pouch affixed to an inner surface of said one side of said bag, intermediate said two arm holes and located between said two arm holes and said bottom edge of said bag.

Claim 5

A device in accordance with claim 3, wherein said bag is formed from 7 mil polyethylene.

Claim 6

A device in accordance with claim 2, further comprising means for introducing negative air pressure into said bag during removal of said hazardous material.

Claim 7

A device in accordance with claim 1, wherein said two side edges are slit from said top edge to provide opposed flaps at said first end.

Claim 8

A device in accordance with claim 1, wherein said disposable device is used in combination with structural means having asbestos insulation thereon, said bag surrounding and extending below at least a portion of said structural means and defining a sealed enclosure, said sealed enclosure receiving and retaining the asbestos insulation removed from said structural means for disposal without subjecting said asbestos insulation to the open atmosphere.

Claim 9

A device in accordance with claim 7, wherein said bag is collapsed and sealed below said at least a portion of said structural means when said sealed enclosure has received the asbestos insulation from said structural means.

Claim 10

In combination for removal of asbestos insulation and like hazardous material, said combination comprising: (a) structural means having asbestos insulation thereon, (b) flexible bag means surrounding and extending below at least a portion of said structural means and defining a sealed enclosure, (c) said flexible bag means including a length of lay-flat tubing having substantially parallel side edges formed by opposed folds of said tubing, substantially parallel top and bottom edges extending substantially perpendicular to said side edges and said flexible bag means further including at least one arm hole and one glove sealed thereto and extending into said sealed enclosure, (d) means defined by said flexible bag means for access of at least one of a tubular wetting device and a vacuum device into said bag, and (e) said sealed enclosure receiving and retaining the asbestos insulation removed from said structural means for disposal without subjecting said asbestos insulation to the open atmosphere.

Claim 11

In combination for removal of asbestos insulation and like hazardous material, said combination comprising: (a) structural means having asbestos insulation thereon, (b) flexible bag means surrounding and extending below at least a portion of said structural means and defining a sealed enclosure, (c) said flexible bag means including a length of lay-flat tubing having substantially parallel side edges formed by opposed folds of said tubing, substantially parallel top and bottom edges extending substantially perpendicular to said side edges and said flexible bag means further including at least one arm hole and one glove sealed thereto and extending into said sealed enclosure, (d) means defined by said flexible bag means for access of at least one of a tubular wetting device and a vacuum device into said bag, and (e) said sealed enclosure receiving and retaining the asbestos insulation removed from said structural means for disposal without subjecting said asbestos insulation to the open atmosphere.

Claim 12

The combination as claimed in claim 9, wherein said flexible bag means is collapsed and sealed below said at least a portion of said structural means when said sealed enclosure has received the asbestos insulation from said structural means.
