Patent Document

[0001]    This application is a non-provisional claiming priority from provisional application 61/490,564 filed May 26, 2011, entitled Environmental Containment, the disclosure of which is incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention is in the field of environmental containment. 
       DISCUSSION OF RELATED ART 
       [0003]    A variety of different environmental containment systems have been created for limiting the contamination of workers and the surrounding environment while dealing with the removal of hazardous materials. The most rudimentary environmental containment system has often been a bag with minimal entrance from the outside to prevent the escape of hazardous materials. Sometimes there are two holes for entrance of the hands to handle the materials inside the containment bag. Other environmental containment systems have been described in the art including United States patents. 
         [0004]    For example, U.S. Pat. No. 4,626,291, issued on Dec. 2, 1986 to Natale, the disclosure of which is incorporated here by reference, is a portable containment device for treatment of hazardous materials, a containment bag system adopted for the purpose of removing asbestos insulation in an environmentally friendly manner. The containment bag with little access for outside particles to enter and with little leeway for containments from within to escape the bag, is a method for removing hazardous materials from limited areas. Natale further extends this idea to U.S. Pat. No. 4,812,700 on Mar. 14, 1989 to portable containment device specifically used for the treatment of hazardous materials such as the removal of asbestos insulation from pipes and valves that contain asbestos and possesses the potential of contaminating the active worker or the surrounding environment. This containment bag system requires a lay-flat tubing to be heated and sealed on the bottom edge and preferably heated and sealed along the two side edges as well. 
         [0005]    In U.S. Pat. No. 4,817,644 issued to Holmes et al. on Apr. 4, 1989, the disclosure of which is incorporated herein by reference, a new and improved apparatus was introduced as an environmental containment system entitled apparatus and method for the safe and effective, large scale removal and disposal of hazardous materials from building components. This apparatus consists of non-rigid materials that are impervious to hazardous materials; and thus, allowing the user of the apparatus to effectively contain the hazardous materials within the elongate close-ended sheets. 
         [0006]    In U.S. Pat. No. 5,520,449 issued on May 28, 1996, the disclosure of which is incorporated herein by reference, Klak features an asbestos glove bag. The glove bag includes two small holes for the hands to enter through the glove bag. It also comprises of a zip-loc closure within glove bag. The flap of the zip-loc closure is attached to the glove bag adjacent to an open top. This system requires a pressure sensitive adhesive strip. The removal of this strip will trigger the disposal of the hazardous materials it contains. 
         [0007]    Other inventors have found that allowing for the portion of the waste-receiving containment bag to me sealed in addition to the containment bag itself being sealed is an additional safety measured. This is outlined in U.S. Pat. No. 4,883,329 issued to Flannery et al. on Nov. 28, 1989, the disclosure of which is incorporated herein by reference, to an environment containment system entitled asbestos containment bag with slide fastener closure. It consists of a gusset and slide fastener assembly inside the containment bag to allow for the adjustment of the waste-receiving portion of the containment bag. The bag can be sealed, unsealed, and resealed to accommodate for the quantity of hazardous materials. 
         [0008]    Browning found in U.S. Pat. No. 6,149,252 issued on Nov. 21, 2000, the disclosure of which is incorporated herein by reference, that an environmental containment system is best structured as a glove box. A cylinder-shaped box is attached to the ceiling. There is a hole at the bottom of the cylinder-shaped box to allow for the user to reach into it to make cuts in the ceiling. The closed cylinder-shaped box then collects any dust, debris, and environmental contaminants from the cutting operation to allow for proper disposal.

The wall frame is made of 4 sections, namely a top section  43 , a bottom section  44 , a left section  42  and a right section  41 . As seen in the first figure, the top section has over a 16 inch distance length. The wall frame is placed over wall studs and mounting brackets  47  are provided with screw openings so that a user can drive a screw into the wall to attach the wall frame to the wall. On the left panel, or left section, the left panel includes a tool magnet  48  for holding tools such as a screwdriver or drywall knife. On the right panel, a hose opening allows connection to a hose. The bottom panel is shown with a HEPA filter. 
         [0126]    An opening for the filter allows mounting of the filter in the opening. The top panel has a spring hinged flap access allow passage of tools downward to the tool magnet. The flap is sealed normally and is held closed by a spring and optionally a latch. The latch can be opened to allow passage of a tool to the wall frame. Four supports can provide additional structure for the wall frame. In an alternate embodiment, the elements can be placed in different orientations, such as if the filter were placed on the left side opposite the hose on the right side. In the primary embodiment, the air flow passes upward from the filter and flows out through the hose opening. 
         [0127]    In  FIG. 2 , the magnet is shown as a strip running the width of the left panel. Although the panels can be made of wood, they can also be formed as plastic members. The four supports can provide for interlocking plastic members. During transportation of the wall frame, the panel members are preferably carried in a bag stacked together. When assembled, the wall frame is preferably airtight. 
         [0128]    A hoop system can be formed as a rectangular inner ring that fits with a rectangular outer ring. In  FIG. 3 , the inner ring and outer ring are shown as rectangular frames sandwiching and outer edge of a glove bag. The glove bag is preferably airtight against the inner ring and the outer ring. 
         [0129]    The pair of rings can be connected together by interference fit, magnetic, or by adhesive means. The inner ring and outer ring can be connected to the wall frame by interference fit, by magnetic means or by adhesive means. 
         [0130]    The wall frame may have a slot formed in the top member in the side members to provide an insertion from the top of the pair of rings including the inner ring and outer ring. The wall frame and the pair of rings is preferably square shaped to allow sideways or upside down mounting. The bag shown in  FIG. 4  provides a glove bag having a pair of gloves attached to a bag and then having a lower area to carry debris.

The right section or left section preferably has a tool magnet  48  mounted to it as well. The left or right section, also called the side sections are supported by the tape as well as the top mounting brackets  47  and the bottom mounting brackets  49 . The side sections when formed as planks are preferably connected to the top section  43  with top corner supports  46 . The side sections when formed as planks are also preferably connected to the bottom section  44  by bottom corner supports  45 . The bottom corner supports  45  can be formed as wooden elongated members. Alternatively, the top mounting brackets  47  can be secured to the top section and the bottom mounting brackets  49  can be secured to the bottom section. 
         [0132]    The top section  43  preferably has a top opening  51  with a top opening hinge  54  that opens inward and is spring-loaded so that it closes the top opening flap with an air tight seal. The top section can also have a top opening flap that opens outward, but this is not preferred. The bottom section can have a bottom opening  52 . The bottom opening  52  includes a filter for filtering air so that air is moving upward. 
         [0133]    In an improved version of the present invention, the filter assembly is a side filter  88  mounted on a left or right side of the wall frame  40 . As seen in  FIG. 7 , four small circular filters can be used. Additionally, in vacuum  89  such as an integrated vacuum can be mounted to the side of the wall frame  40 , opposite the side filters  88 . In the improved version of the present invention, the airflow flows from the side filters side of the apparatus to the vacuum site of the apparatus. The vacuum may have a variable control on it. The suction opening  53  optionally includes an air filter for filtering air leaving the unit. It is preferred that the side filters  80  are mounted on a side filter openings disposed in a side of the wall frame  40 . With an integrated vacuum, the housing of the vacuum can be mounted directly to the wall frame  40 , or can be connected to the suction opening  53  by a hose. It is preferred that the tape  90  is color contrasting to the side of the wall frame  40 .

         [0139]    The seventh step  67  is to attach a 6 mil bagging system such as glove bag  30 . The eighth step  68  is too wet in the area by missing with a small spray bottle having a wetting agent. The ninth step  69  is to turn on the Hepa Vacuum and then insert hands into the bagging system. The 10 th  step is to cut a hole with the recommended drywall hand saw. The 11 th  step  71  is to remove the drywall and place it in the glove bag  30 . The drywall will generally rest of the floor toward the bottom of the glove bag  30 . The 12 th  step  72  is to drop in the vacuum attachment and clean the bay area of all debris and dust. The 13 th  step  73  is to seal the top and bottom of the bay with poly strips and industry tape. The 14 th  step  74  is to mist the area making sure that debris and the bag is adequately wet but not pooling at the bottom. The 15 th  step  75  is to wipe the area and tools and to remove all of the tools except for the screwdriver. The 16 th  step  76  is to wet wipe the screwdriver and to reclean the area. 
         [0140]    The 17 th  step  77  is to temporarily seal the bag with industry duct tape. The 18 th  step  78  is to encapsulate the cut area with a lock down encapsulate spray. The 19 th  step  79  is to let the area dry for 15 minutes. The 20 th  step  80  is to vacuum out air inside the glove bag, then twist the bag and minimum of five turns and applied industry tape to close the bag. The bagging system is then detached and the bag is goose necked which means to be folded over again. The bag is twisted a minimum of five turns during closing. It is preferred to apply tape and the place the glove bag  30  into another 6 Mil clear bag which is then also taped in the same manner. The 21 st  step  81  is to fill out a label and attach the label to the bag. The label should have the details of: Homeowner, Date, Contents, Address and a notation of Cad981400518 Epa Residential Not Commercial. The 22 nd  step  82  is to cut or remove tape around the wall mount. The 23 rd  step  83  is to remove and disassemble the wall mount. The 24 th  step  84  is to make any necessary repairs. The 25 th  step is to cover the hole was a poly sheet of plastic and tape in place. The 26 th  step is to have materials tested before for the removal or debris is discarded and to leave always on-site until testing results are completed. A card such as a hotline number can be provided by a plumber. 
         [0141]    A second embodiment of the pocket containment method  160  is the best mode of the present invention. The pocket containment method  160  has a number of steps, and may have other steps not included in the listed steps. The first step  161  is to detect the access area. The second step  162  is find the wall studs and measure and mark for cutting the area. The third step  163  is to isolate the area with critical carriers such as poly plastic sheet over doors and air vents and other air openings. The fourth step  164  is to assemble the wall mount with tools in place and to tape the outer connection points. The fifth step  165  is to attach the wall apparatus with all four screws making sure that they are mounted to the bay studs. The sixth step  166  is to tape all four edges with industry duct tape all around the wall mount and walls inside and out. The seventh step  167  is to attach the recommended HEPA vacuum hose and duct tape around both nozzles. The eighth step  168  is to wet the area by missing it with a small spray bottle of a wetting agent such as alcohol or water. The ninth step  169  is to attach a 6 mil bagging system with a glove bag attached between the outside mounting ring and the inside mounting ring. The 10 th  step  170  is to tape with teal colored duct tape inside, along the bottom and all along the bagging system edge and wall mount. 
         [0142]    The 11 th  step  171  is to turn on the HEPA vacuum and adjusts the flow with a dampener so that the bag doesn&#39;t collapse too much. The 12 th  step  172  is to use a respirator before opening the wall. The 13 th  step  173  is to insert hands into the bagging system. The 14 th  step  174  is to cut a hole with a drywall hand saw. The 15 th  step is to remove the drywall and place it in a bag. The 16 th  step  176  is to drop in the vacuum attachment and clean the bay of all debris and dust and remove the bottom strip of tape that was put on the bottom of the bagging system. The bay area is cleaned. The 17th step  177  is to mist the area making sure that the debris of the bag is adequately wet but not pooling at the bottom hollow of the bag. The 18th step  178  is to wet wipe around the area and tools and remove the tools except for the screwdriver. 
         [0143]    The 19th step  179  is to remove the bottom strip of tape that was put on bottom of bagging system and discard.
