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 855.460 - Removal Procedures

Current through Register Vol. 48, No. 28, July 12, 2024
The contractor shall remove ACBM in accordance with the
				  following procedures:
a) The work area
				shall be cleaned and isolated in accordance with Sections
				855.400,
				855.410,
				855.420,
				855.425,
				855.430,
				855.440
				and
				855.450.
b) All ACBM shall be wetted with an amended
				water solution using equipment capable of providing a fine spray mist in order
				to reduce airborne fiber concentrations when the material is disturbed. The
				material shall be saturated to the substrate; however, excessive water shall
				not be allowed to accumulate in the work area. All removed material shall be
				kept wet enough to prevent fiber release until containerized for disposal. A
				high humidity in the work area shall be maintained by misting or spraying to
				assist in fiber settling and to reduce airborne concentrations.
c) Saturated ACBM shall be removed and
				containerized before moving to a new location for continuance of work.
				Surrounding areas shall be periodically sprayed and maintained in a wet
				condition until visible material is cleaned up.
d) Material removed from building structures
				or components shall not be dropped or thrown to the floor. Material shall be
				removed as intact sections or components whenever possible and carefully
				lowered to the floor. If this cannot be done for materials greater than 50 feet
				above the floor, a chute which does not allow dust to escape shall be
				constructed to transport the material to containers on the floor or the
				materials shall be containerized at elevated levels (e.g., on scaffolds) and
				carefully lowered to the ground by mechanical means. Materials between 15 and
				50 feet above the ground may be containerized at elevated levels or dropped
				onto inclined chutes for subsequent collection and containerization.
e) Containers (six mil polyethylene or
				equivalent labeled bags or labeled drums) shall be sealed when full. ACBM shall
				be double bagged when polyethylene bags are used for disposal. Double bagging
				shall occur in the work area. Bags shall not be overfilled. The bags shall be
				sealed to prevent accidental opening and leakage by tying the tops in an
				overhand knot or by taping in gooseneck fashion. Bags shall not be sealed with
				wire or cord. Bags may be placed in drums for staging and transportation to the
				landfill. Bags shall be decontaminated on exterior surfaces by wet cleaning
				before being placed in clean drums and sealed with locking ring tops.
f) Large components shall be wrapped in two
				layers of six mil polyethylene or equivalent sheeting, secured with tape and
				labeled ACBM prior to transport to the landfill.
g) Asbestos-containing waste materials with
				sharp-edged components (e.g., nails, screws, metal lath, tin sheeting, floor
				tile, and metal ceiling components) which may tear the polyethylene bags or
				sheeting shall be placed into drums for disposal. In lieu of disposal drums,
				floor tile may be wrapped in two layers of reinforced plastic or one layer of
				burlap and two six mil labeled polyethylene or equivalent bags.
h) After completion of stripping of ACBM,
				surfaces from which asbestos-containing building materials have been removed
				shall be cleaned (e.g., wet brushed and sponged) to remove all visible
				residue.
