Illinois Administrative Code › Title 77 - PUBLIC HEALTH › Part 855 - ASBESTOS ABATEMENT FOR PUBLIC AND PRIVATE SCHOOLS AND COMMERCIAL AND PUBLIC BUILDINGS IN ILLINOIS › Subpart E - LOCAL EDUCATIONAL AGENCY RESPONSIBILITIES AND STANDARDS FOR ABATEMENT › Section 855.465 - Cleanup Procedures

Current through Register Vol. 48, No. 28, July 12, 2024
The contractor shall perform the cleanup in accordance with
				  the following procedures:
a) The
				negative pressure ventilation units shall remain in continuous
				operation.
b) Decontamination
				enclosure systems shall remain in place, remain functional at all times, and be
				utilized.
c) All visible
				accumulations of ACBM and asbestos-contaminated debris shall be removed and
				containerized. Tools which are not electrically conducting and which have no
				sharp edges or corners likely to tear containment barriers (e.g., rubber dust
				pans, rubber squeegees, or plastic shovels) shall be utilized.
d) All containerized waste shall be removed
				from the work area and the holding area on a daily basis. The contractor may
				temporarily store ACBM in large metal, locked dumpsters or an enclosed truck at
				the abatement site. At the conclusion of the abatement project, all temporarily
				stored ACBM shall be removed from the abatement site and be transported to a
				regulated landfill location approved for disposal of asbestos-containing
				waste.
e) The contained area shall
				be thoroughly cleaned in accordance with the following procedures:
1) First cleaning: all surfaces in the
				contained area shall be wet cleaned using rags, mops and sponges. To pick up
				excess water and gross wet debris, a wet-dry shop vacuum or HEPA vacuum may be
				used. If a vacuum is used, it shall be decontaminated prior to removal from the
				contained area. The contractor shall then wait a minimum of 12 hours before
				proceeding with clean-up.
2) At the
				conclusion of the 12 hour waiting period, if no water is visible on surfaces,
				the cleaned first layer of plastic sheeting shall be removed from the walls and
				floors. The sheeting shall be folded inward and bagged for disposal.
3) Second cleaning: the second layer of
				plastic sheeting and all objects and surfaces in the contained area shall be
				HEPA vacuumed and/or wet cleaned. The contractor shall then wait a minimum of
				12 hours before proceeding to the next step.
4) If no visible moisture remains on surfaces
				in the contained area at the conclusion of the 12 hour period, the cleaned
				second layer of plastic sheeting shall be removed from the walls and floors.
				The sheeting shall be folded inward and bagged for disposal.
5) Third cleaning: windows, doors, HVAC
				system vents and all other openings shall remain sealed. All objects and
				surfaces in the work area shall be HEPA vacuumed and wet cleaned. The
				contractor shall wait a minimum of 12 hours drying time before
				proceeding.
6) If all surfaces in
				the contained area are dry at the end of the 12 hour period, the contractor
				shall inspect the contained area for visible residue. If any accumulation of
				residue is observed, the residue will be assumed to be asbestos and the process
				described in step 5 shall be repeated.
