Asbestos Abatement Guidelines and Policies <br />Page 01410-2 <br /> <br />D. The industrial hygiene firm has the authority to direct the contractor relative to safety <br />and environmental concerns. This includes stopping the work if necessary. All directions <br />and comments made by the industrial hygiene firm to the contractor shall be written <br />with a copy to the designer. <br /> <br />E. The SAM shall review and make comments to the designer on the submittals listed in <br />Section 01043. <br /> <br />F. The SAM shall approve any change in contractor’s respiratory protection. This includes <br />a review of the historical data. <br /> <br />G. The industrial hygiene firm is to conform to the contractor's schedule and shall respond <br />to necessary changes, provided an advance notice is given as outlined in Section 01043. <br /> <br />H. The industrial hygiene firm’s project monitor shall furnish designer and contractor with <br />a mobile phone number where he can be reached quickly at all times. <br /> <br />1.03 AIR MONITORING <br /> <br />A. First day air sampling followed by periodic monitoring is recommended for this project <br />in order to document and observe the asbestos abatement work. <br /> <br />Ambient Air Monitoring: The purpose of ambient air monitoring by the industrial hygiene <br />firm will be to detect discrepancies in the work area isolation such as: <br /> <br /> 1. Contamination of the building outside of the work area with airborne asbestos <br />fibers. <br /> <br /> 2. Failure of filtration or rupture in the negative pressure system. <br /> <br /> 3. Confirm the work practices established by the contractor and respiratory <br />protection provided for employees are adequate. <br /> <br />B. Work Area Airborne Fiber Levels: The owner's industrial hygiene firm will monitor <br />airborne fiber levels in the work area. The purpose of this air monitoring will be to detect <br />airborne fiber levels which may challenge the ability of the work area isolation procedures <br />to protect the balance of the building or outside of the building from contamination by <br />airborne fibers. <br /> <br />C. Work Area Clearance: To determine if the elevated airborne fiber levels encountered <br />during abatement operations have been reduced to an acceptable level, the industrial <br />hygiene firm will sample and analyze air per Section 01714. <br /> <br />D. In accordance with AHMB Program Rules, the SAM shall develop an Abatement Project <br />Monitoring Plan which complies with EPA and OSHA analytical criteria and will provide a <br />valid representation of airborne fiber concentrations both inside and outside the work <br />area. This program is not intended to satisfy the contractor's requirement for sampling <br />DocuSign Envelope ID: 09980A3B-0691-41B4-854D-3865F2287392
