Sec.19a-332a-5. General requirements for asbestos abatement projects

(a) Signs shall be posted which meet the specifications set forth in 29 CFR 1926.1101(k)(7)(ii)(A) at all approaches to the work area. Signs shall be posted a sufficient distance from the work area to permit a person to read the sign and take precautionary 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.

(d) All movable objects which can be removed from the work area shall be removed. Cleaning of contaminated items shall be performed if the item is to be salvaged or reused. Otherwise the item shall be properly disposed of as asbestos waste. All non-movable objects in the work area shall be covered with a minimum of 6 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 prevent leaks. There shall be no seams in the polyethylene sheet at the wall-to-floor joints.

(f) Work area access shall be restricted to authorized personnel afforded proper respiratory protection and protective clothing.

(g) Clean-up procedures shall involve high efficiency particulate air (HEPA) filtration and wet cleaning techniques. Amended water shall be used. The sequence of wet cleaning and HEPA-filtered vacuuming shall be repeated until no visible residue is observed in the work area.

(h) Negative pressure ventilation units with HEPA filtration shall be provided in sufficient number to allow at least one (1) work place air change every 15 minutes. Filtered air should be exhausted to areas outside the building which are not near any intake for the building ventilation system.

(i) Waste water generated during asbestos abatement shall be filtered by best available technology prior to discharge.

(j) All asbestos containing waste shall be adequately wetted with an amended water solution and be placed in leak-tight containers.

(k) All leak-tight containers shall be labeled in accordance with OSHA 29 CFR 1910.1200 and EPA 40 CFR Part 61.152 as appropriate.

(l) Disposal of asbestos waste shall be at an authorized asbestos disposal facility. If the authorized asbestos disposal site is located within Connecticut, written authorization for disposal shall be obtained from the Department of Environmental Protection, Bureau of Waste Management.
