Clothing which has been used shall be tested for the effectiveness of asbestos laundering using nondestructive adhesive sampling of three or more randomly selected areas taken from within a portion of the clothing chest area and analysis of the samples by PCM. To allow the clothing to be used, samples must have an average fiber area concentration of 40 fibers or less; elevated samples may be analyzed by PLM and TEM for further definition of the nature of the fibers to determine whether the criterion is met with respect to asbestos fibers. Clothing contamination testing shall be performed under the environmental monitoring program of this Section, and include a quality control program specific to this testing which provides for testing at least 1 of 200 pieces of used clothing, and rejection of all pieces of a laundry batch in which any of the p9eces exceed the criterion (pending relaundering followed by testing).

PART 3 – EXECUTION

3.01 PREPARATION OF FULL WORK AREA ENCLOSURES:

A. Prior to commencing work the Contractor shall inspect, for prior damage, all items located in the intended work area and provide the Contracting Officer a written list and photographs of any existing damage.

B. Shut down then lock off all air handling equipment serving the intended work area. The Contractor shall retain the keys to locks to prevent the air handling equipment from being turned on prematurely before satisfactory final clearance air samples have been obtained after completion of the asbestos work.

C. Thoroughly preclean the work area. This shall include removal of all dust and debris from the work site. Use HEPA vacuum cleaners and wet wiping with amended water for the final effort. All wastes and scrap collected shall be considered asbestos contaminated and will be disposed of as asbestos waste.

D. Seal off all openings and fixtures in the work area including but not limited to electrical fixtures, heating and ventilation ducts, doorways, corridors and windows with plastic sheeting taped securely in place. Seal all penetrations in walls, ceilings and floors using expanding foam or other non-asbestos filler material.

1. If the work area involves an elevator lobby and the elevators cannot be shut off for the duration of the asbestos work, cover the elevator door openings with plywood, caulk around the edges of the plywood, then cover the plywood with two layers of plastic sheeting. The plastic sheeting should extend at least six inches beyond the plywood on the walls and floor then attached firmly in place with a moisture resistant tape, adhesive, or both.

E. Install critical barriers using overlapped layers of plastic sheeting at all entrances and exits so that the work area is always closed off by one barrier when workers enter or exit.

F. Except where ACM is to be removed, cover all non removable items of equipment and/ or furnishings with plastic sheeting taped securely in place.

G. Except for surfaces where ACM is to be removed, cover all ceilings, walls and floors with layers of plastic fixed firmly in place. Use at least two layers of 4-mil plastic on ceilings and walls. Use at least three layers of 6-milplastic on floors in occupied areas; two layers in mechanical areas. Property overlap layers at least twelve inches to prevent water intrusion under the plastic.

H. Install an approved decontamination unit with clean room, shower and equipment room. Shower water must be properly filtered to remove particles five microns in size or larger before discouraging the waste water into the sewage system. Where possible, also install separate decontamination facilities appropriate for cleansing containers of properly packaged asbestos waste as they are removed from the work area.

I. Install HEPA filter equipped ventilation equipment to maintain a pressure differential of 0.02 inches of water (as a goal) in the work area. Pressure differential must be sufficient to provide four air changes per hour in the work area. Testing company field technician shall smoke test to check seals and verify desired air flow form the outside to the inside of the work area through decontamination areas or other prepared locations. Once established, the pressure differential must be maintained continuously until the work area has passed final clearance air sampling. The exhaust from the HEPA ventilation equipment should be discharged to the outside building whenever possible. When this is not possible and the exhaust must be discharged inside of the building, the area into which the exhaust is discharged must be air monitored constantly to ensure airborne fiber counts do not exceed the asbestos control limits.
