21 M. The Abatement Contractor shall seal all ventilation openings (supply and exhaust), doorways, convectors, and other areas in/into the work areas with duct tape alone or with polyethylene sheeting at least 6-mil in thickness taped securely in place with duct tape. All necessary equipment, casework, cabinetry (i.e. sinks) shall be removed prior to the gross abatement process. N. The Abatement Contractor shall provide self-contained, single occupant toilet units of the chemical, aerated recirculation, or combustion type. Provide units properly vented and fully enclosed with a glass-fiber-reinforced polyester shell or similar nonabsorbent material. O. The Abatement Contractor shall provide First Aid Supplies complying with governing regulations and recognized recommended within the construction industry REMOVAL PROCEDURES ACMS It is not intended that all procedures listed herein are required or that all procedures are listed herein. A. Wet all ACM with amended water solution using equipment capable of providing a fine spray mist, in order to reduce airborne fiber concentrations when the material is disturbed. Saturate the material to the substrate, however, do not allow excessive water to accumulate in the work area. Keep all removed material wet enough to prevent fiber release until it can be containerized for disposal. B. Saturated ACM shall be removed in manageable sections. Surrounding areas shall be periodically sprayed and maintained in a wet condition until visible material is cleaned up. C. Utilize P100 vacuums as sections are lifted to remove dust, dirt, or debris that might be disturbed. D. All ACM material removed shall be carefully bagged and transported to a closed top/lockable dumpster lined with 6-mil poly. The Abatement Contractor is to limit the amount of waste and provide continuous removal from the work area. The waste load out will consist of a minimum two-stage system. NOTE: All gross material will be removed from the containments at the end of each work shift. Also waste load out through the decontamination unit will not be acceptable unless work space constraints become an issue. t:\companyfiles\2012\ \ndot - - \Specs Section

22 E. Asbestos-containing wastes with sharp-edged components (e.g., nails, screws, metal lathe, tin sheeting), which may tear the polyethylene bags and/or sheeting shall be placed into an approved container for transport and disposal. F. Dumpsters used for friable material shall be lined with two (2) layers of 6-mil polyethylene sheeting. Only closed top dumpsters shall be used, and the dumpster shall be kept locked at all times other than waste load-out. G. Remove and containerize all visible accumulations of asbestos-containing material and asbestos contaminated debris. H. Maintain surface of the exterior asbestos control areas and all containment areas so that they are free of accumulations of asbestos debris.

Encapsulation of the containment areas will be permitted only after visual inspection and PCM clearances are completed and approved by the Owner s Representative. PAINT STABILIZATION A. Regulated Area: A regulated work area shall be established for all work. The work area shall be secured from access by all unauthorized personnel.

Barrier tape labeling will consist at a minimum Caution Lead Hazard - Do Not Enter or an approved equivalent. The Contractor shall provide one (1) layer of 6-mil polyethylene sheeting as close to the foundation out a minimum distance of 10 feet. The sheeting shall be weighted at the foundation and along all edges and seams. It will be required to erect vertical shrouds or suspend work if constant wind speed exceeds 15 mph or there is visible movement of debris beyond ground sheeting. On a daily basis all dust and debris will be collected by HEPA vacuuming the surface or by wet sweeping. At the end of each work day, all polyethylene sheeting shall be removed and placed in 6 mil disposable bags. The material will then be secured with other waste. On a daily basis and during the final cleanup the Abatement Contractor shall visually examine the immediate area to ensure that no debris has escaped the regulated area. Wet sweep or rake up debris found and place in waste containers. B. Suspend all work activities during inclement weather, which may include rain, snow, ice and hail. C.

A Shower room with a completely watertight operational shower to be used by workers headed out of the Work Area after undressing in the Equipment Room/Dirty Room. The shower will be equipped with showerhead and controls, hot and cold water, soap, and shampoo. A three-stage water filtration system will be employed before release of water into the local sewage system. c. A Hot Water Heater will be utilized for the Decontamination Unit Shower. This equipment will be a UL rated minimum 40 gallon (150 Liters) electric hot water heater. Activate from 30 amp circuit breaker located within the Decontamination Unit sub panel.
