The sheets of polyethylene shall be hung from the top of the wall, 2 inches below the asbestos material and shall be long enough to overlap the floor sheets by approximately 24 inches. The vertical sheets shall be overlapped and seam-sealed with adhesive duct tape.

d. Where feasible, and at locations requested by the County representative, the Contractor shall install windows of clear plexiglass within the containment walls, to allow the County representative clear visibility into the contained area.

e. It may be necessary in some instances to use nails and wood blocks to secure the polyethylene when duct tape cannot support the weight of the polyethylene (as when humidity is excessive). The Contractor shall reinforce the containment structure as needed to provide proper negative pressure-gross containment conditions.

8. Emergency and Fire Procedures

a. The Contractor shall establish emergency and fire procedures for evacuation. Emergency and fire procedures shall have priority over decontamination procedures.

b. The Contractor shall have arrows marking the exits and fire extinguishers on site.

9. Negative Air Pressure Within the Enclosure

a. After construction of the enclosure is complete, a ventilation system shall be installed by the Contractor to create a negative pressure within the enclosure with respect to the area outside the enclosure. This system shall be equipped with HEPA filters meeting specifications established in ANSI Standard 29.2-79. The system shall be required to produce a negative pressure of 0.02 inches of water column within the enclosure. The system shall provide at least four (4) air changes per hour. Negative air exhaust shall not be vented into the building(s).

b. The negative pressure system shall be operated in accordance with Appendix

J., pages J-1 through J-8, of the EPA Guidance Manual No EPA 560/85-024, entitled "Recommended Specifications and Operating Procedures for the Use of Negative Pressure Systems for Asbestos Abatement".

c. If during the removal process negative pressure is not maintained in the work area, all removal operations shall be immediately suspended. The County shall be notified immediately.

NOTE: Mandatory Smoke Test of the Enclosure Area shall be performed in ALL OSHA Class I Asbestos Abatement operations. This test shall consist of a two stage smoke test operation. Stage one, shall be performed without negative pressure; to ensure that all seams and openings are completely sealed and no smoke migrates outside the Work Area. Once Stage one is accomplished stage two shall be performed to ensure that proper air movement is occurring within the Work Area and is acceptable by the Qualified Person or County representative

E. Removal Process

1. The removal process shall begin once the work preparations have been finished, inspected, and approved.

2. The Contractor shall have a licensed asbestos supervisor on the job at all times (during work hours) to ensure that the enclosure, engineering controls, work methods and personal protective equipment are in compliance with all governing regulations and these specifications. The supervisor shall ensure that unauthorized personnel do not enter the enclosure and that all personnel that do enter the enclosure observe proper protection and decontamination procedures.

3. All asbestos-containing materials shall be thoroughly wetted with amended water to enhance penetration prior to executing removal. Thorough wetting of the asbestos-containing materials shall continue throughout the removal operations.

4. At the beginning of each workday, all polyethylene barriers shall be checked to ensure that they are still intact. Corrections/reparations shall be made prior to resuming asbestos removal activities.

5. Upon removal, the asbestos material shall be thoroughly wetted again and placed directly into waste bags. Asbestos-containing waste shall not accumulate on the floor before bagging. Asbestos waste bags shall not be dropped, thrown or otherwise carelessly handled at any time.

6. The waste bags shall be properly sealed immediately after filling.

7. It is advantageous to the clearance process to conduct removal towards the HEPA-filtered negative air machines. Once the bulk (gross) asbestos-containing material has been removed, efforts can be directed toward cleaning operations.

8. Removal Via Mini-enclosure

a. Small scale-short duration abatement tasks (cleaning surfaces for wall and ceiling penetrations, drilling of holes, installing mounting for conduit etc.) may be performed under mini-enclosure conditions with the preapproval of the County.

b. Mini-enclosure construction and work methods shall follow guidelines established in 29 CFR 1926.1101 Appendix G.

c. Proper respiratory equipment in accordance with 29 CFR 1910.134, as suitable for the asbestos exposure in the work area, shall be used for the duration of the project. Sufficient filters for replacement of disposable filters shall be provided by the Contractor.

d. The Project Monitor shall perform a visual inspection on each mini enclosure prior to completion/removal of unit. The Project Monitor may also choose to conduct clearance sampling prior to granting final clearance. Airborne fiber counts less than .01 f/cc shall be required prior to achieving final clearance.

9. Removal Via Negative Pressure Glove-Bags

a. Removal of asbestos-containing materials via negative pressure glove-bag techniques (as specified in these documents and in OSHA 29 CFR 1926.1101) may be performed only in areas preapproved by project designer.

b. All glove-bag set-up and asbestos removal activities shall be performed by two workers wearing proper respiratory equipment in accordance with 29 CFR 1910.134, as suitable for the asbestos exposure in the work area. Workers performing asbestos removal via glove-bag shall also wear disposable protective coveralls and gloves.

c. Areas affected by glove-bag removal of asbestos- containing materials shall be thoroughly pre-cleaned utilizing wet-wiping and HEPA-vacuuming equipment. At least one layer of 6 mil fire retardant polyethylene shall be used under each glove-bag as a drop cloth.

d. Workers shall thoroughly wet asbestos-containing materials prior to, and during asbestos removal activities. A wetting agent shall be utilized if water repelling asbestos-containing materials is encountered.

e. Each individual glove-bag unit shall be inspected and granted visual clearance by the Project Monitor prior to tear-down. All interior areas of each glove-bag shall be thoroughly encapsulated prior to tear down.

10. Removal of Asbestos-Containing Flooring Materials

a. Removal of asbestos-containing flooring and mastic materials shall be performed under negative pressure gross containment conditions as specified above, except that floors, walls and ceilings are not required to be covered with 6-mil polyethylene plastic. However, if floor mastic is being removed, a 3-foot tall “splash guard” consisting of 6-mil polyethylene plastic shall be constructed at the base of all walls within the contained area.

b. Nondestructive or “Armstrong” removal methods shall be permitted only in locations where quantities of asbestos-containing floor tile and/or mastic to be abated total 10 square feet or less.

c. Nondestructive or “Armstrong” removal of asbestos-containing floor tile and mastic shall be performed in accordance with the procedures outlined in the texts “Recommended Work Procedures For Resilient Floor Coverings” 1980/1987, and “Resilient Floor Tile, Asphaltic ‘Cutback’ Mastic, Sheet Vinyl Flooring, Instructions for Removal”, June 1993, issued by the Resilient Floor Covering Institute, 966 Hungerford Drive, Suite 12-B Rockville Maryland, 20850. Failure to follow the procedures as presented in the above listed texts shall result in the return to negative pressure gross containment conditions and/or work stoppage.

d. Construction activities with the potential for disturbing asbestos-containing flooring materials (drilling and/or driving of nails through asbestos-containing flooring materials et. al.) shall be performed by properly trained and protected personnel in accordance with these specifications.

F. Cleaning Operations

1. Upon completion of gross removal, the substrate shall be thoroughly brushed, and repeatedly wet-wiped with amended water.

2. The following steps shall be performed in sequential order:

a. All surfaces shall be thoroughly wet-wiped, allowed to dry, and wet-wiped again until all visual evidence of residual asbestos-containing materials has been eliminated (fine cleaning process).

b. Rags and water used for wet-wiping shall be continually changed. Rags utilized in the wet-wiping process shall be disposed of as asbestos-contaminated waste.

All asbestos - contaminated water shall be filtered (5.0 micron filtration) prior to being released in the sanitary sewer system.

c. The top (outer) floor layer of the equipment room shall be removed after fine cleaning has been completed to ensure that tracking of asbestos dust does not occur from this area.

d. Any visual debris shall be removed by HEPA vacuuming and/or wet-wiping.

e. Removal of gross contamination from all equipment in the work area shall be the final step of the fine cleaning process.

f. Equipment shall be wet-wiped, washed off in shower and removed from work area (except negative air machines). Tools such as scrapers, utility knives, brushes, etc., shall be sealed in plastic and transported to other jobs.

g. Following completion of fine cleaning, a thorough visual inspection will be conducted by the County. Lock down (encapsulation) of the work area may proceed only after visual clearance of the containment is granted by the Project Monitor. Failure of the visual inspection shall require the Contractor to provide additional labor until the work area is deemed acceptable by the County. An approved encapsulant material (provide SDS for review prior to application) shall be applied to the substrate and all other surfaces throughout the work area.

h. Following encapsulation, a period of 24 hours shall elapse to allow the encapsulant to dry, prior to initiating final air clearance procedures. Failure of air clearance sampling shall result in the re-execution of fine cleaning activities by the Contractor until satisfactory air sampling results are achieved.

i. Following the 24 hour waiting period, satisfactory air clearance monitoring and final visual inspection, removal of the inner (bottom) polyethylene layers shall take place.

j. All floors shall be wet-mopped. All walls shall be wet-wiped.

k. All critical barriers, decontamination unit, windows, HVAC system, electrical outlets, penetrations, and negative air machines shall be left in place until the project has been given final approval by the Project Monitor.
