56-8.4 Handling and removal procedures.
(a) Glovebag procedures.
Glovebags are allowed to be utilized for abatement of pipe or duct insulation within negative pressurized regulated abatement work area enclosures. Glovebags may only be used on piping and ducts up to 150°F. The following procedures must be followed for glovebag use:
(1) Size. When abating pipe or duct insulation, the pipe or duct insulation diameter worked shall not exceed one half the bag working length.
(2) Sealing. Duct tape shall be placed securely around the area of abatement to form a smooth seal. The glovebag shall then be secured to the duct tape and sealed airtight.
(3) Seal testing. After placement, each glovebag shall be subjected to and pass a smoke test as follows:
(i) Smoke testing should not be completed using a positive pressure test. The glovebag, once secured in place, should be placed under negative pressure, utilizing the HEPA-vacuum, and a smoke tube should be aspirated to direct smoke at all seals and seams from outside the glovebag.
(ii) If there are any leaks, they will be detected by the smoke entering the bag. All leaks shall be duct taped airtight.
(4) Surface irregularities. If material adjacent to the work section is damaged, or if it terminates, is jointed or contains an irregularity adjacent to the work section, the material shall be wrapped in at least six mil fire-retardant plastic sheeting and sealed airtight with duct tape.
(5) Post-stripping wetting. After the asbestos material has been stripped, the surface from which it has been removed shall be wetted with amended water and scrubbed with a brush or abrasive pad to remove all visible asbestos material. The surfaces from which it has been removed, the interior of the bag, the affected area and the tools shall then be thoroughly wetted with amended water.
(6) Sealing of pipe ends. When abating pipe insulation, any pipe insulation ends created shall be sealed with wettable cloth or otherwise encapsulated with a non-asbestos product.
(7) Collapsing of the glovebag. A HEPA-vacuum shall be used to collapse the glovebag.
(8) Tool segregation. With the glovebag collapsed and the asbestos material in the bottom of the bag, twist the bag several times and duct tape the twist to seal that section. The tool pouch shall be separated from the bag by twisting it several times, taping the twist and thus sealing the pouch. Alternately, the tools may be segregated using one or both glove inserts and pulling the tools through, thus turning the glove inside out. The glove(s) shall then be twisted several times, duct taped and thus sealed.
(9) Sealing the contaminated items. The glovebag shall be tied off to contain the asbestos material prior to the glovebag being detached from the area where the asbestos was removed within the bag.
(10) Containerizing the glovebag. The sealed glovebag shall be placed into at least a six mil plastic bag, sealed airtight and transferred from the regulated abatement work area as per section 56-8.9 of this Subpart, for disposal as asbestos waste.
(11) Failure. The requirements of section 56-8.2(g) of this Subpart shall be complied with in the event of glovebag losing seal or integrity.
(b) Dry removal or dry disturbance.
No dry removal or dry disturbance of asbestos material shall be permitted.
(c) Wetting requirements.
The asbestos material shall be adequately wetted with amended water. Sufficient time shall be allowed for penetration to occur prior to abatement activities. All friable asbestos materials shall be thoroughly saturated. All non-hygroscopic (material that resists wetting) asbestos material shall be thoroughly wetted, prior to and during abatement.
(d) Asbestos abatement.
Only one type of asbestos containing material shall be abated at a time within an enclosure. Prior to the abatement of another type of asbestos containing material, the area shall be cleaned. (See section 56-8.6 of this Subpart -multiple abatement within a single regulated abatement work area.)
(e) Handling.
ACM, PACM and asbestos material, on detachment from the substrate, shall be directly bagged or dropped into a flexible catch basin and subsequently bagged or containerized. Materials removed in negative pressure tent enclosure work areas shall be bagged or containerized immediately upon detachment. Additional amended water shall be added as necessary to the waste bags/containers to ensure that all waste remains adequately wet within the bag/container.
(f) Sealing of surfaces and edges.
Where ACM, PACM or asbestos material was removed, any exposed edges of material that remain shall be sealed with wettable cloth or otherwise encapsulated with a suitable non-asbestos material, prior to commencement of final cleaning and collection of clearance air samples.
(g) Exterior chutes.
For asbestos material lowered or conveyed greater than 10 feet in height, dust tight, enclosed, inclined chutes shall be used as follows:
(1) The upper end of the chute shall be furnished with a hinged lid to be closed when a chute is not being used.
(2) The chute shall be dust tight along its lateral perimeter and at the terminal connection to a dumpster or container with a hard wall and a hard top.
(h) Handling large components.
Large components, removed intact, shall be wrapped in two layers of at least six mil plastic sheeting secured and made air tight with duct tape.
(i) Sharp-edge components.
Asbestos waste material with sharp edged components that may tear or damage the plastic bags or sheeting shall be placed in a poly lined hard wall container or a rip proof bag then double bagged or wrapped and sealed airtight.
(j) Loss of integrity on asbestos projects.
If a regulated abatement work area enclosure of any type, including a negative pressure tent enclosure, fails or loses its integrity, the required procedures of section 56-8.2(g) of this Subpart shall be followed.
