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 855.400 - Work Area Preparation

Current through Register Vol. 48, No. 28, July 12, 2024
The asbestos abatement contractor shall perform the following
				  steps, in the order in which they appear, to prepare the work area. The
				  contractor shall:
a) Complete the
				requirements in Section
				855.430. Any
				barriers, such as temporary walls or ceilings, needed to completely enclose the
				work area, shall be constructed in accordance with Section 855.430.
b) Post caution signs meeting the
				specifications of OSHA
				29 CFR
				1926.1101(k)(6) at any
				location and approaches to a location where airborne concentrations of asbestos
				may exceed ambient background levels. Signs shall be posted to permit a person
				to read the sign and take the necessary protective measures to avoid exposure
				before entering the work area.
c)
				Shut down and lock out electric power to all contained areas on a daily basis.
				"Shut Down and Lock Out" means to switch off all electrical circuit breakers
				serving power or lighting circuits which run to, or through, the contained
				area. Label circuit breakers with tape over the breakers with the notation
				"DANGER, circuit being worked on". Lock the electrical door or panel with
				separate locks, one lock and key for the supervisor and one lock and key for
				the project manager. No other personnel shall have keyed access to the
				electrical power in the contained area. Provide temporary power and lighting
				and ensure safe installation of temporary power sources and equipment in
				accordance with the National Electrical Code (see Section
				855.10(b)(1)
				). All power to work areas shall be brought in from outside the area through
				ground-fault circuit interrupters at the source.
d) Shut down and isolate heating, cooling,
				and ventilating air systems to prevent contamination and fiber dispersal to
				other areas of the structure. Remove all HVAC system filters and place in
				labeled six mil polyethylene or equivalent bags for disposal as
				asbestos-contaminated waste. Clean the filter assembly and outside of the duct
				work using HEPA vacuums or wet cleaning techniques.
e) Seal off all openings to windows,
				corridors, doorways, skylights, ducts, grills, diffusers, and any other
				penetrations of the work areas, with six mil plastic or equivalent sheeting
				sealed with tape. Also seal all seams in system components that pass through
				the contained area. Doorways and corridors which will not be used during work
				must be sealed with barriers as described in Section 855.430.
f) Proposed contained area.
1) Where friable ACBM is present in the
				proposed contained area as defined in the asbestos management plan and/or
				project designer's specifications, the following shall be conducted by the
				contractor:
A) Pre-clean movable objects
				within the proposed work areas using HEPA filtered vacuum equipment and/or wet
				cleaning methods, as appropriate, and remove such objects from work areas to a
				temporary location.
B) Upholstered
				furniture and drapes shall be HEPA vacuumed twice before removal from the work
				area.
C) Carpeting shall be removed
				and disposed of as asbestos-containing waste material, unless the following are
				complied with:
i) Take one representative bulk
				sample from each homogeneous material which shall include the carpet fiber, the
				carpet backing, and the carpet mastic.
ii) The bulk samples shall be analyzed by
				Transmission Electron Microscopy (TEM). If the samples are found to contain no
				asbestos fibers, the carpet may remain in place if protected from
				contamination.
iii) Cover carpets
				that have been reported as containing no asbestos fibers with two layers of six
				mil poly or equivalent or place 7/16" plywood or equivalent over the layer of
				six mil poly and then place two additional layers of six mil poly over the
				7/16" plywood.
iv) Upon completion
				of the abatement operations, the carpeting shall be re-sampled (as described in
				subsection (f)(1)(C)(i) of this Section). If the carpet is reported to contain
				asbestos fibers, the carpet shall be removed and disposed of as
				asbestos-containing waste.
D) Pre-clean fixed objects and specific
				equipment items which will remain within the proposed contained areas, using
				HEPA filtered vacuum equipment and/or wet cleaning methods as appropriate. The
				fixed objects shall then be wrapped with a minimum of one layer of six mil poly
				or equivalent.
E) Pre-clean the
				proposed contained areas using HEPA filtered vacuum equipment and/or wet
				cleaning methods as appropriate. Methods that raise dust, such as dry sweeping
				or vacuuming with equipment not equipped with HEPA filtration, are prohibited.
				ACBM shall not be disturbed during pre-cleaning.
