9.1 Air Monitoring

The CONSULTANT will conduct air monitoring throughout the course of the project. The CONSULTANT will perform field analysis of the air samples. At the CONSULTANT’S option, a microscope and field laboratory will be set up at the jobsite in order that verbal reports of air monitoring may be obtained promptly after collection and analysis.

The CONSULTANT’S reports to the OWNER will include air monitoring data and pertinent information on work being conducted such as: work hours, number of workers, procedures used, CONTRACTOR discrepancies and corrective measures, containment methods and construction, and amount of ACM removed.

Work Area Isolation

The CONSULTANT will monitor airborne fiber counts outside the Work Area. The purpose of this air monitoring will be to detect faults in the Work Area isolation including, but not limited to, contamination of the building outside of the Work Area with airborne asbestos fibers, failure of filtration or rupture in the ventilation system, or contamination of the exterior of the building with airborne asbestos fibers.

Should any of the above occur, the CONTRACTOR shall immediately cease asbestos abatement activities until the fault is corrected. Work shall not recommence until authorized by the CONSULTANT.

The CONSULTANT will monitor airborne fiber counts in the Work Area. The purpose of this air monitoring will be to detect airborne fiber counts which may significantly challenge the integrity of Work Area isolation procedures that protect the balance of the building or outside of the building from contamination by airborne fibers.

Inside Work Area

Maintain an average airborne count in the Work Area of less than 0.1 fibers per cubic centimeter (f/cc) of air. If the fiber counts rise above this figure for any sample taken, revise work procedures to lower fiber counts. If the Time Weighted Average (TWA) fiber count for any Work shift or 8-hour period exceeds 0.1 f/cc, stop work, and leave ventilation system in operation. Do not recommence work until authorized by the CONSULTANT.

Outside Work Area

Maintain an average airborne count outside the Work Area of less than the Permissible Exposure Limit (PEL) of 0.1 f/cc of air.

If any air sample taken outside the Work Area exceeds the PEL, immediately stop work until the source of the elevated fiber readings can be determined by the CONSULTANT. Immediately take corrective as instructed by the CONSULTANT.
