Approx. 650 LF. See attached piping drawing. Duct Insulation Associated With AHU-A1, AHU-2, AHU-3, AHU-A4 and FA- RA-1. Approx. 1,300 SF. See attached HVAC duct drawing. The above materials shall be removed licensed by asbestos workers in personal protective equipment (PPE) inside negative pressure containment using wet removal methods and proper waste disposal. All abatement activities must be performed in accordance with applicable Department of State Health Services (DSHS) Texas Asbestos Health Protection Rules (TAHPR), EPA NESHAP and applicable OSHA regulations. OSHA approved glove bag methods may be used on pipe insulation only as needed Work area shall be equipped with the following: Regulated areas within which asbestos abatement is to be conducted shall be separated from adjacent areas by impermeable barriers of four (4) mil polyethylene sheeting attached securely in windows, doorways, corridor entrances, ventilation openings (both air supply and return air), drains, ducts, grills, grates, diffusers and skylights, shall be sealed with a minimum of a single layer of six (4) mil polyethylene sheeting. All penetrations that could permit air infiltration or air leaks through the barriers shall be sealed, with exceptions of the make-up air provisions and the means of entry and exit All asbestos shall be placed into labeled, 6-mil poly impermeable bags (double bagged) or wrapped in two layers of 6-mil poly.
