Post OSHA DANGER signs meeting the specifications of OSHA 29 CFR 1926.1101 at any <br />location and approaches to the regulated area where airborne concentrations of <br />asbestos may exceed ambient background levels. Signs shall be posted at a distance <br />sufficiently far enough away from the regulated area to permit any personnel to real the <br />sign and take the necessary measures to avoid exposure. Additional signs will be posted <br />following construction of the regulated area enclosure. <br /> <br />1.02 FULL CONTAINMENT (CATEGORY I Friable Removal) – Floor Tile and Mastic <br /> <br />A. The contractor shall wet clean and/or HEPA vacuum all items and equipment in the <br />work area suspected of being contaminated with asbestos, but not in direct contact with <br />the asbestos material and either secures these items in place with 6-mil (minimum) <br />polyethylene plastic sheeting (poly) or has them removed from the work area. <br /> <br />B. Critical Barriers: The contractor shall thoroughly seal the work area for the duration of <br />the work by sealing off individual openings and fixtures in the work area, including, but <br />not limited to, heating and ventilation ducts, doorways, corridors, windows, and <br />skylights, with poly securely in place. If the contractor is using sealant materials to fill in <br />small holes or cracks, the material shall have appropriate fire ratings. <br /> <br />C. Light fixtures shall be cleaned (using HEPA-vacuums and wet techniques). <br /> <br />D. Poly shall be installed in such a manner that they may be removed independently of <br />each other and the critical barriers. <br /> <br />E. Entrances and exits from the work area will have triple barriers of poly so that the work <br />area is always closed off by one barrier when workers enter or exit. <br /> <br />DocuSign Envelope ID: 09980A3B-0691-41B4-854D-3865F2287392
