New York Codes, Rules and Regulations › Title 12 - DEPARTMENT OF LABOR › Chapter I - Industrial Board Of Appeals › Subchapter A - The Industrial Code › Part 56 - Asbestos › Subpart 56-8 - Phase Ii B Asbestos Abatement › Section 56-8.6 - Multiple abatement within a single regulated abatement work area

Current through Register Vol. 46, No. 28, July 10, 2024
(a) Simultaneous
					 abatement. Simultaneous or concurrent abatement of multiple types of ACM within
					 a single regulated abatement work area shall not be allowed, unless the
					 multiple types of ACM are part of the same system (e.g., floor tile/cove base
					 and mastics, or ceiling/wall tile and mastic). Simultaneous removals are
					 allowed on a project as long as they are within different regulated abatement
					 work areas.
(b) Requirements for
					 sequential abatement. When multiple types of abatement work are done in a
					 common regulated abatement work area or enclosure, a sequential order of
					 abatement is required as shown below.
(1)
					 Initial plasticizing. Initial plasticizing of the containment area shall be as
					 required for the most stringent case of removal.
(2) Sequential removal. Sequential removal
					 shall allow for only one type of removal of ACM at a time in a sequential order
					 within the work area until that type of material is completely removed.
					 Thereafter, another type of ACM can be removed within the same work area.
					 Relief from plasticizing is for the surfaces to be abated only at the time of
					 that specific material abatement. Other surfaces shall be plasticized as the
					 material being abated dictate, except as noted below.
(i) Order of sequential abatement. The
					 following sequence of abatement within a work area shall begin at the ceiling
					 or upper level and progress one material at a time down to the floor and from
					 most friable material to least friable material.
(ii) Example:
(a) First. All ceiling fireproofing, ceiling
					 plaster or similar ceiling OSHA Class I friable material shall be completely
					 abated so that no visible exposed ACM, PACM or asbestos material remains. Then
					 the friable mechanical/tank insulation, isolation/ vibration damper material
					 and thermal pipe, ducts, pipe fitting insulation, mudded firebrick, or similar
					 OSHA Class I or Class II friable material shall be completely abated so that no
					 visible exposed material remnants remain. Glovebags may be used. After all
					 friable ACM has been abated, the area shall be cleaned of all debris/residue
					 using HEPA vacuuming and wet wiping.
(b) Second. OSHA Class II non-friable
					 materials shall be abated. If other areas/surfaces were abated, no new
					 plasticization shall be required. Ceiling and wall tiles, transite, interior
					 window glazing, expansion joint, millboard and other NESHAP Category I and II
					 non-friable ACM shall be abated so that no visible exposed material remnants
					 remain and the area shall be cleaned of all debris/residue using HEPA vacuuming
					 and wet wiping.
(c) Last. OSHA
					 Class II non-friable flooring abatement shall be last. Non-friable ACM flooring
					 materials and ACM mastic shall be abated so that no visible exposed material
					 remnants remain and the area shall be cleaned of all debris/residue using HEPA
					 vacuuming and wet wiping. If beadblaster or a similar abrasive type of
					 abatement method is used, full work area preparation, including establishment
					 of negative pressure filtration systems, shall be required and this abatement
					 may be done as one of the first types of abatement and then the flooring area
					 abated shall be re-plasticized with a double-layer of six-mil fire-retardant
					 plastic sheeting, to be utilized as a dropcloth during the remaining
					 abatement.
(iii)
					 Temporary walls. New temporary hardwalls used to separate an enclosed regulated
					 abatement work area into smaller regulated abatement work area enclosures shall
					 be constructed as per section
					 56-7.11(b) 
					 of this Part. Existing columns, I beams and interior walls may be used to
					 support or to act as part of the new containment walls provided that the
					 existing walls, columns, and I beams to which these temporary walls are to be
					 attached or used shall be completely abated prior to the erection of these new
					 containment walls to allow this attachment. Caulk, fire-retardant expandable
					 foam or duct tape shall be used to form an airtight seal for these partitions.
(a) Airlock. Each newly enclosed regulated
					 abatement work area shall have an attached airlock as defined in section
					 56-2.1  of this
					 Part, and the airlock shall be constructed at the enclosure entrance, as per
					 section
					 56-7.5(b)(11) 
					 of this Part. Each enclosure and airlock shall be cordoned off 25 feet from its
					 perimeter. Critical openings within the cordoned off area shall be covered with
					 two layers of six mil fire-retardant polyethylene in conformance to section 56-
					 7.11(a) of this Part.
(iv) Intermediate completions. On completion
					 of each type of asbestos abatement within these work area enclosures, a
					 complete single clean of all surfaces in the entire area - ceiling, walls and
					 floors - shall be performed by HEPA vacuuming and wet wiping. No final
					 clearance air samples shall be required for each individual type of material
					 abatement, until the last type of ACM, PACM or asbestos material is abated.
					 Each intermediate completion shall include a visual inspection for completeness
					 by the supervisor. Results of the visual inspection and time of intermediate
					 completion shall be documented by the supervisor in the daily project
					 log.
(v) Final required cleaning. A
					 complete single clean of all surfaces in the entire area -- ceiling, walls and
					 floors, followed by a visual inspection as described in Subpart 56-9 of this
					 Part shall be performed by HEPA vacuuming and wet wiping, after all abatement
					 is complete.
(vi) Final clearance
					 air samples. After the final cleaning and visual inspection requirements are
					 completed and the final settling/drying period is observed, prior to
					 dismantling the regulated abatement work area, Phase IIC final clearance air
					 samples shall be collected and satisfactory clearance air results obtained as
					 per section
					 56-9.2 
					 of this Part.
