Disconnect electrical service before wet removal is performed.

1. Class I Asbestos Materials Removal:

a. The Class I asbestos containing materials must be removed inside negative pressure enclosures as identified in the Abatement Contractor’s work plan submittal and approved by the 92 CONS Contracting Officer.

b. Position HEPA filtration air scrubbing equipment in a manner that creates continuous air filtration in the work zone during removal activities.

B. Access to Isolated Work Area by Others. Except for the Abatement Contractor's authorized personnel, and the 92 CONS Contracting Officer, or regulatory officials conducting compliance inspections, the Abatement Contractor shall limit access to the work area.

C. General. Monitoring of airborne concentrations of asbestos fibers shall be in accordance with 29 CFR 1910.1001, 29 CFR 1926.1101, and as specified herein.

1. Review. Personnel and procedures utilized by the Abatement Contractor are subject to review of the 92 CONS Contracting Officer. All air monitoring shall be performed by the Abatement Contractor’s qualified monitoring personnel.

2. Records. Documentation shall be kept for each filter sample procured as to worker sampled, work area, location, date and time taken, volume of air drawing through filter, pump identification number and calibration.

3. Samples. The samples shall be forwarded to an independent testing laboratory, approved by the 92 CONS Contracting Officer for analysis. The laboratory analyst shall sign and submit permanent records of all samples analyzed to the 92 CONS Contracting Officer with the sample records. Each sample must be labeled as to location, results of analysis, date, laboratory and project.

D. Monitoring Prior to Asbestos Work. Provide area monitoring and establish the reference TWA one-day prior to masking and sealing operations for each demolition site.

1. Pre-abatement Air Sampling. A minimum of one (1) air sample inside each work area and one

(1) air sample outside each work area shall be taken before abatement is completed in that area. Minimum sample shall be 480 liters.

2. Post Abatement Air Sampling. A minimum of one (1) air sample inside each work area and one (1) air sample outside each work area shall be taken after abatement is completed in that area. Minimum sample shall be 480 liters.

E. The Abatement Contractor shall determine current waste handling, transportation and disposal regulations for the work site and each waste disposal landfill. Abatement Contractor shall comply fully with these regulations and all US Department of Transportation and EPA requirements. Label and signs shall be in accordance with EPA and OSHA standards.

F. Final Work Area Cleanup. Abatement Contractor shall clean all surfaces in the work area and any other contaminated areas with water and/or with HEPA filtered vacuum equipment. After cleaning the work area, perform a visual inspection to ensure that the work area is free of visible asbestos debris. During this settling period, no entry, activity, or ventilation will be allowed.

G. Post abatement air sampling shall be taken within 24 hour of final cleaning. When the final inspection by the 3rd Party Industrial Hygienist and air sampling test results are satisfactory, the decontamination systems and remaining barriers shall be removed.

3.2 CLEAN-UP

A. Remove visible accumulations of asbestos-contaminated material and debris. Wet clean all surfaces within the work area.

1021.10 028300 - 17

B. During cleaning operations windows, doors shall remain sealed and any HEPA filtration negative air pressure systems, air filtration and decontamination enclosure systems shall remain in service.
