F. Tools and Local Exhaust System: Provide a local exhaust system in the asbestos control area. Filters on vacuums and exhaust equipment shall be UL 586-labeled HEPA filters. Local exhaust equipment shall be sufficient to maintain a minimum pressure differential of minus 0.02 inch of water column relative to adjacent, unsealed areas.

Provide a manometer-type negative pressure differential monitor with minor scale division of 0.02 inch of water and accuracy within plus or minus 1.0 percent. Calibrate the manometer daily as recommended by the manufacturer. Provide manually recorded manometer readings of the pressure differential between the asbestos control area and adjacent unsealed areas at the beginning of each workday and every 2 working hours thereafter. The local exhaust system shall be operated continuously, 24 hours a day, until the asbestos control area enclosed is removed. Replace filters as required to maintain the efficiency of system. The building heating, ventilating, and air conditioning (HVAC) system shall not be used as the local exhaust system for the asbestos control area.

2.1 WORK PROCEDURE: Perform asbestos-related work in accordance with 29 CFR

1926.1101 and as specified herein. Use wet removal procedures. Personnel shall wear and use protective clothing and equipment as specified herein. Eating, smoking, drinking, chewing tobacco or chewing gum shall not be permitted in the asbestos control area. Personnel of other trades not engaged in the removal and demolition of asbestos shall not be exposed at any time to airborne concentrations of asbestos in excess of 0.01 fibers unless the personnel protection provisions of this specification are complied by the trade personnel. Shut down the building HVAC system. Disconnect electrical service when wet removal is performed and provide temporary electrical service protected by a ground fault circuit interrupter.

A. Furnishings: If equipment in the asbestos control area is contaminated with asbestos fibers, provide wet cleaning during asbestos control area cleanup procedures. (Draperies and other items which may not be susceptible to on-site wet cleaning methods shall be laundered in accordance with 29 CFR 1926.1101.)

B. Masking and Sealing:

1. Asbestos Control Area Requirements (For all areas except for the removal of the built-up roofing system): Seal openings in areas where the release of airborne asbestos fibers is expected. Establish an asbestos control area with the use of curtains, portable partitions, or other enclosures in order to prevent the escape of asbestos fibers from the contaminated asbestos control area. The established control area shall be provided with protection coverings of walls and ceilings with a continuous membrane of two layers of minimum 6-mil plastic sheet sealed with tape to prevent water or other damage and two layers of 6-mil plastic sheet over floors extending a minimum of 24 inches up walls. All penetrations of the floor, walls, and ceiling shall be sealed with 6-mil polyethylene plastic and duct tape. Seal joints using spray adhesive and duct tape. Openings will be allowed in enclosures of asbestos control areas for the supply and exhaust of air for the local exhaust system.

2. Asbestos Control Area requirements (For the removal of the built-up roofing system): The construction of an enclosed asbestos control area is impractical for the removal of the built-up roofing system material located on building. Provide a 20-foot roped off perimeter around the area where the asbestos handling procedures are performed and maintain other requirements for asbestos control areas. Also, where an enclosure is not provided, the industrial hygienist shall monitor the removal and disposal process to ensure that no asbestos containing material blows or falls off the roof. If adjacent areas become contaminated, clean the contaminated areas, monitor, and visually inspect the areas as specified herein.

C. Asbestos Handling Procedures:

1. General Procedures: Sufficiently wet asbestos material, including floor tile and cement asbestos board, with a fine spray of amended water during removal, cutting, or other handling to reduce the emission of airborne fibers. Remove material and immediately place in plastic disposal bags. When both piping and insulation are to be removed, wet the insulation, then, using glovebag technique remove 10-inch to 12-inch sections of the pipe insulation and encapsulate exposed edges of the asbestos insulation to remain, and remove the pipe. Where unusual circumstances prohibit the use of plastic disposal bags, the industrial hygienist shall submit, in the asbestos plan, an alternate proposal for removal of asbestos materials and containment of asbestos fibers.

2. Exposed Pipe Insulation Edges: Encapsulate exposed edges of asbestos insulation to remain. Wet and cut the rough ends true and square with sharp tools and encapsulate the edges with a 1/4-inch-thick layer of insulating cement troweled to a smooth, hard finish. When cement is dry, lag the end with a layer of fiberglass cloth and thermal insulation adhesive, overlapping the existing ends by 4 inches. When insulating cement and cloth are an impractical method of sealing raw edges of asbestos, take appropriate steps to seal the raw edges as approved by the Contracting Officer. Remove existing asbestos insulation for new piping connections during the asbestos handling and disposal procedures as specified herein.

D. Identification of Asbestos-Free Insulation: Apply "ASBESTOS-FREE" markings to the exterior jackets of nonasbestos-insulated piping installed herein. Letter size shall be in accordance with MIL-STD-101. Apply marking at maximum of 20-foot intervals. Indicate the limits of "ASBESTOS-FREE" insulation with a 1-inch wide band with attached arrow pointing in the direction of the label "ASBESTOS-FREE." Paint markings in orange, No. 12246 of Fed. Std. 595.

E. Monitoring: Monitoring of airborne concentrations of asbestos fibers shall be in accordance with 29 CFR 1926.1101, 40 CFR 763 and as specified herein, whichever is stricter. The Government shall have the option to perform independent monitoring.

F. Site Inspection: While performing asbestos removal work, the contractor shall be subject to on-site inspection by the Contracting Officer who may be assisted by safety or health personnel.

2.2 CLEANUP AND DISPOSAL:

A. Cleanup: Maintain surfaces of the asbestos control area free of accumulations of asbestos fibers. Restrict the spread of dust and debris; keep waste from being distributed over the general area. Do not dry sweep or blow down the space with compressed air. Clean all surfaces in the work area and other contaminated areas with water and/or HEPA vacuum equipment. The CIH or his designated representative shall visually inspect the affected surfaces for residual asbestos material and accumulated dust; the Contractor shall reclean areas showing dust or residual asbestos materials. If recleaning is required, monitor the airborne fiber concentration after recleaning. After cleaning the work area, allow 24 hours for settlement of dust and wet clean or clean with HEPA vacuum equipment all surfaces in the work area. { When asbestos removal, disposal, and cleanup are complete of the built-up roofing system material, the industrial hygienist shall certify, in writing, that all of the asbestos containing material has been removed, the Contractor shall repeat the cleaning until all of the asbestos containing material has been removed, at no additional cost to the Government. Do not remove the asbestos control area roped-off perimeter and caution signs prior to the Contracting Officer's receipt of the industrial hygienist's certification. When asbestos removal, disposal, and cleanup are complete except the asbestos containing built-up roofing system, the industrial hygienist shall certify, in writing, that the concentration of airborne fibers in the control area is less than 70 structures/mm per TEM analysis, using aggressive monitoring procedures, the Contractor shall repeat the cleaning until a satisfactory fiber count is reached, at no additional cost to the Government. Aggressive monitoring will be as detailed in the EPA publication Guidance for Controlling Asbestos-Containing Material in Buildings, Appendix M.1.5. Do not remove the asbestos control area enclosure and caution signs prior to the Contracting Officer's receipt of the industrial hygienist's certification. } After final cleanup, remove filters on the building HVAC system and provide new filters. Dispose of filters as asbestos-contaminated materials. Reestablish HVAC, mechanical, and electrical systems in proper working order. Notify the Contracting Officer before unrestricted entry is permitted. The Government shall have the option to perform independent monitoring to certify the areas are safe before entry is permitted.

B. Disposal of Asbestos: Collect asbestos waste, scrap, debris, bags, containers, equipment, and asbestos-contaminated, clothing which may produce airborne concentrations of asbestos fibers; place in sealed impermeable bags imprinted with a caution label. Dispose of waste asbestos material by burial at the state-approved sanitary landfill (Delaware Solid Waste Authority: Northern Solid Waste Facility - 2 located at Cherry Island, Wilmington, Delaware for Class A asbestos containing materials and Central Solid Waste Facility located at Sandtown, Delaware for Class B asbestos containing materials) off Government property. For temporary storage, store sealed impermeable bags in asbestos waste drums. An area for interim storage of asbestos waste-containing drums will be assigned by the Contracting Officer or by an authorized representative. Procedure for hauling and disposal shall comply with 40 CFR 61, Subpart M, 40 CFR 241 and 257, 49 CFR 171, 172 and 173, and state, regional, and local standards. Sealed plastic bags may be dumped from drums into the burial site unless the bags have been broken or damaged. Damaged bags shall remain in the drum and the entire contaminated drum shall be buried. Uncontaminated drums may be recycled. Workers unloading the sealed drums shall wear appropriate respirators and personal protective equipment when handling asbestos materials at the disposal site.
