PART 3 EXECUTION:

3.1. GENERAL REQUIREMENTS: Asbestos abatement work tasks shall be performed as summarized in paragraph 1.4.1. Use the engineering controls and work practices required in

29 CFR 1926.1101(g) in all operations regardless of the levels of exposure. Personnel shall wear and utilize protective clothing and equipment. Do not permit eating, smoking, drinking, chewing or applying cosmetics in the regulated area. Personnel of other trades, shall not be exposed at any time to airborne concentrations of asbestos unless all the administrative and personal protective provisions of the Contractor's APP are complied with.

Temporary electrical service with ground fault circuit interrupters shall be provided as needed. Temporary electrical service shall be disconnected when necessary for wet removal.

Stop abatement work in the regulated area immediately when the airborne total fiber concentration: (1) equals or exceeds 0.01 f/cc, or the pre-abatement concentration, whichever is greater, outside the regulated area; or (2) equals or exceeds 1.0 f/cc inside the regulated area. Correct the condition to the satisfaction of the CO, including visual inspection and air sampling. Work shall resume only upon notification by the CO.

Corrective actions shall be documented.

3.2. PROTECTION OF ADJACENT WORK OR AREAS TO REMAIN: Perform asbestos abatement without damage to or contamination of adjacent work or area. Where such work or area is damaged or contaminated, it shall be restored to its original condition or decontaminated at no expense to the Government. When spills occur, work shall stop in all affected areas immediately and the spill shall be cleaned. When satisfactory visual

June 2012 inspection and air sampling analysis results are obtained and have been evaluated by the

Contractor's Designated IH and the CO, work shall proceed.

3.3. BUILDING VENTILATION SYSTEM AND CRITICAL BARRIERS: Roof level heating and ventilation air intake sources shall be isolated by airtight seals. or the ventilation system shall be shut down.

3.4. METHODS OF COMPLIANCE:

3.4.1. Mandated Practices: The specific abatement techniques and items identified shall be detailed in the Contractor's AHAP. Use the following engineering controls and work practices in all operations, regardless of the levels of exposure:

a. Vacuum cleaners equipped with HEPA filters, as modified to incorporate the removal of roofing material containing ACM.

b. Wet methods or wetting agents except where it can be demonstrated that the use of wet methods is unfeasible due to the creation of electrical hazards, equipment malfunction, and in roofing, as modified to incorporate the removal of roofing material containing ACM.

c. Prompt clean-up and disposal, as modified to incorporate the removal of roofing material containing ACM.

3.4.2. Control Methods: Use the following control methods:

a. Enclosure or isolation of processes producing asbestos dust;

b. Where the feasible engineering and work practice controls are not sufficient to reduce employee exposure to or below the PELs, use them to reduce employee exposure to the lowest levels attainable and shall supplement them by the use of respiratory protection.

3.4.3. Unacceptable Practices: The following work practices shall not be used:

a. High-speed abrasive disc saws that are not equipped with point of cut ventilator or enclosures with HEPA filtered exhaust air.

b. Compressed air used to remove asbestos containing materials, unless the compressed air is used in conjunction with an enclosed ventilation system designed to capture the dust cloud created by the compressed air.

c. Dry sweeping, shoveling, or other dry clean up.

d. Employee rotation as a means of reducing employee exposure to asbestos.

3.4.4. Class I Work Procedures and Specific Control Methods: Class I work operations are not part of this contract. In the event that Class I Asbestos Containing Material

a. A Competent Person shall supervise the work.

3.4.6. Specific Control Methods for Class II Work :

3.4.6.1. Roofing Material : When removing roofing materials which contain ACM as described in 29 CFR 1926.1101(g)(8)(ii), use the following practices as shown in RESPONSE ACTION DETAIL SHEET [74] [75]. Roofing material shall be removed in an intact state. Wet methods shall be used to remove roofing materials that are not intact, or that will be rendered not intact during removal, unless such wet methods are not feasible or will create safety hazards. When removing built-up roofs, with asbestos-containing roofing felts and an aggregate surface, using a power roof cutter, all dust resulting from the cutting operations shall be collected by a HEPA dust collector, or shall be HEPA vacuumed by vacuuming along the cut line. Asbestos-containing roofing material shall not be dropped or thrown to the ground, but shall be lowered to the ground via covered, dust-tight chute, crane, hoist or other method approved by the CO. Any ACM that is not intact shall be lowered to the ground as soon as practicable, but not later than the end of the work shift. While the material remains on the roof it shall be kept wet or placed in an impermeable waste bag or wrapped in plastic sheeting. Intact ACM shall be lowered to the ground as soon as practicable, but not later than the end of the work shift. Unwrapped material shall be transferred to a closed receptacle. Critical barriers shall be placed over roof level heating and ventilation air intakes.

3.4.6.2. Other Class II work operations (ie, Vinyl and Asphalt Flooring Materials operations, or Cementitious Siding and Shingles or Transite Panel Operations, or

Gasket Operations) are not covered by these specifications.

3.4.7. Specific Control Methods for Class III Work: (Bulk Samples) Class III asbestos work shall be conducted using engineering and work practice controls which minimize the exposure to employees performing the asbestos work. The work shall be performed using wet methods and, to the extent feasible, using local exhaust. Use impermeable drop cloths and shall isolate the operation, using mini-enclosures or glovebag systems, where the disturbance involves drilling, cutting, abrading, sanding, chipping, breaking, or sawing of TSI or surfacing material. Taking bulk samples during an asbestos survey is a Class III operation, and, as in all class III operations, a respirator is required when there is no negative exposure assessment

3.4.8. Specific Control Methods for Class IV Work : CLASS IV ACM work operations is not part of this contract.

3.4.9. Class II Asbestos Work Response Action Detail Sheets: The following Class II

Asbestos Work Response Action Detail Sheet is specified for each individual work task to be performed:

a. Built-Up Roofing and Flashing: See Sheet 74

3.5. FINAL CLEANING AND VISUAL INSPECTION: After completion of all asbestos removal work and the gross amounts of asbestos have been removed from every surface, any remaining visible accumulations of asbestos shall be collected. Upon completion of the cleaning, conduct a visual pre-inspection of the cleaned area in preparation for a final

02 82 14.00 15 Asbestos Hazard Control Activities (Roofing)

Page 22 of 30 Pages

June 2012 inspection. The Contractor and the CO shall conduct a final visual inspection of the cleaned regulated area in accordance with ASTM E 1368 and document the results on the Final

Cleaning and Visual Inspection as specified on the SET-UP DETAIL SHEET 19. If the CO rejects the clean regulated area as not meeting final cleaning requirements, reclean as necessary and have a follow-on inspection conducted with the CO. Recleaning and follow-up reinspection shall be at the Contractor's expense.

3.6. LOCKDOWN: Prior to removal of plastic barriers and after final visual inspection, a

(lockdown) encapsulant shall be spray applied to roof decking in the regulated area.
