			 measures to avoid exposure to asbestos.
(b) The facility heating, ventilating and air
			 conditioning (HVAC) systems within the asbestos abatement work area shall be
			 shut down, locked out and isolated to prevent contamination of and fiber
			 dispersal to other areas of the facility.
(c) The work area shall be isolated from
			 non-work areas by air-tight barriers attached securely in place. All openings
			 between the work area and non-work areas including but not limited to windows,
			 doorways, elevator openings, corridor entrances, ventilation openings, drains,
			 ducts, grills, grates, diffusers and skylights, shall be sealed airtight with 6
			 mil polyethylene sheeting.

			 mil polyethylene sheeting secured in place.
(e) Floor and wall surfaces in the work area
			 shall be covered with polyethylene sheeting or equivalent. All seams and joints
			 shall be sealed with tape or equivalent. Floor covering shall consist of at
			 least two layers of 6 mil polyethylene and must cover at least the bottom 12
			 inches of adjoining wall. Wall covering shall consist of a minimum of two
			 layers of 4 mil polyethylene sheet which shall overlap the floor covering to

			 protection and protective clothing.

			 labeled in accordance with OSHA
			 29 CFR
			 1910.1200 and EPA 40 CFR Part 61.152 as
