Double bagging of waste material is required. Bags shall not <br /> be over ~ full with all air evacuated out of the bag using a HEPA <br /> vacuum. They should be securely sealed to prevent accidental opening <br /> and leakage by tying tops of bags in an overhand knot or by taping in <br /> gooseneck fashion. Do not seal bags with wire or cord. (Bags may be <br /> placed in drums for staging and transportation to the landfill. Bags <br /> shall be decontaminated on exterior surfaces by wet cleaning and HEPA <br /> vacuuming before being placed in clean drums and sealed with locking <br /> ring tops). <br /> <br /> 3.4.6 Large components removed intact may be wrapped in 2 layers of 6-mil <br /> polyethylene sheeting secured with tape and properly labeled for <br /> transport to the landfill. <br /> <br /> 3.4.7 Asbestos containing waste with sharp-edged components (e.g. nails, <br /> screws, metal lath, tin sheeting) will tear the polyethylene bags and <br /> sheeting and shall be placed into drums for disposal. <br /> <br /> 3.4.8 Asbestos containing thermal insulation shall be removed utilizing <br /> glove bags with the appropriate procedures to be followed in which <br /> the bag is taped in place around the pipe, the insulation is cut <br /> inside the bag following spraying with wetting agent. The material <br /> is then removed, dropped into the bottom of the bag. The pipe is <br /> cleaned by brushing with nylon brush and then an encapsulant is <br /> sprayed on the bare pipe. The ends of the insulation which have been <br /> cut inside the bag are sealed, and then the glove bag is removed. It <br /> is evacuated using the HEPA vacuum in order to collapse it, and then <br /> tied so that it can be removed. Material removed by glove bag <br /> procedure will then be placed in 6-mil polyethylene bag for disposal. <br /> In no instance will a single glove bag be used to remove more than 3 <br /> linear feet of asbestos containing material or be moved to another <br /> section of piping once it is attached. <br /> <br />3.5 Clean-up Procedure <br /> <br /> 3.5.1 Remove and containerize all visible accumulations of asbestos <br /> containing material and asbestos contaminated debris utilizing rubber <br /> dust pans and rubber squeegees to move material around. <br /> Do not use metal shovels to pick up or move accumulated waste. <br /> <br /> Special care shall be taken to minimize damage to floor sheeting. <br /> <br /> 3.5.2 Remove all containerized waste from the work area and waste container <br /> pass-out airlock. <br /> <br />4/11/03 70 <br /> <br /> <br />
