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 56-9 - Phase Ii C Final Cleaning And Clearance Procedures › Section 56-9.1 - Final cleaning procedures

Current through Register Vol. 46, No. 28, July 10, 2024
The following cleanup procedures shall be required after
						completion of Phase II B activities:
(a) Continuous negative pressure ventilation.
					 If required during Phase II B, the negative pressure ventilation units shall
					 remain in continuous operation during implementation of Phase II C, including
					 observance of settling/waiting periods and drying times.
(b) First cleaning, lockdown encapsulation
					 and top layer removal. All surfaces of the regulated abatement work area shall
					 be first wet-cleaned using rags, mops and sponges. For collecting excess liquid
					 and wet debris, a wet purpose HEPA filtered shop vacuum may be used and shall
					 be emptied prior to removal from the regulated abatement work area. When the
					 first cleaning has been completed, a thin coat of a lockdown encapsulant agent
					 shall be applied to all surfaces within the regulated abatement work area which
					 were not the subject of removal or abatement. In no event shall lockdown
					 encapsulant be applied to any surface which was the subject of removal or other
					 abatement response activity, prior to obtaining satisfactory clearance air
					 results for the regulated abatement work area. Once the lockdown encapsulant
					 has been applied, and the appropriate waiting/settling or drying time
					 requirements of this Subpart have been met, the cleaned, exposed top barrier
					 layer of plastic sheeting shall then be removed from walls, ceilings and
					 floors. Windows, doors, HVAC system vents and other openings shall remain
					 sealed. Decontamination system enclosures shall remain in place and shall
					 continue to be utilized.
(c) Second
					 cleaning and bottom layer removal. After the top layer of plastic sheeting has
					 been removed, all objects and surfaces in the regulated abatement work area
					 shall be HEPA-vacuumed and then wet-cleaned. After the second cleaning and
					 waiting/settling or drying time requirements of this Subpart, then the
					 remaining bottom layer of plastic sheeting on walls, ceilings and floors shall
					 be removed. All windows, doors, HVAC system vents and all other openings shall
					 remain sealed.
(d) Third or final
					 cleaning and visual inspection. After the bottom layer of plastic sheeting has
					 been removed, all objects and surfaces in the regulated abatement work area
					 shall be HEPA-vacuumed and then wet-cleaned. After the final cleaning is
					 complete, clearance air sampling shall not commence until the appropriate
					 waiting/settling or drying time requirements of this Subpart have elapsed and a
					 visual inspection has been completed by the project monitor to confirm that the
					 scope of abatement work for the asbestos project is complete, and no visible
					 asbestos debris/residue, pools of liquid, or condensation remain. The asbestos
					 abatement contractor supervisor must complete a satisfactory visual inspection
					 for completeness of abatement and cleaning, prior to commencement of the
					 project monitor visual inspection.
(1)
					 Project monitor visual inspection. An appropriately trained and certified
					 project monitor, contracted by the building/structure owner, independent of the
					 asbestos abatement contractor, shall complete the visual inspection. The
					 project monitor visual inspection for completeness of abatement and
					 completeness of cleanup shall be performed as per the provisions of the current
					 ASTM standard E1368 "Standard Practice for Visual Inspection of Asbestos
					 Abatement Projects". If the property owner is the asbestos abatement contractor
					 for the asbestos project, the owner shall contract with an independent project
					 monitoring firm asbestos contractor for the necessary visual inspection on the
					 asbestos project. The asbestos abatement contractor and property owner, prior
					 to the scheduling of the required visual inspection, shall provide a complete
					 abatement scope of work for the asbestos project to the project monitor. An
					 entry shall be made into the asbestos abatement contractor supervisor's daily
					 log by both the supervisor and the individual performing the inspection,
					 detailing the findings of the visual inspection. The full name and NYSDOL
					 asbestos handling certificate number of the certified individual performing the
					 inspection shall also be documented in the supervisor's daily log.
