SHLnManufacturing Guideline Numbr G3-19 Pag* Dal* Sept. 1984 2 4.1 Pipe Insulation | Most pipe Insulation Installed prior to 1972 contains arfrastos. Generally maintenance and/or replacement of insulated pipes requites removal of the adsestos covering. To minimize the release of asbestos fibers ktto the air and decrease potential employe exposure, the following work practices must be followed! 4.1.1 All employes removing adbestos pipe Insulation must wear approved respirators and special clothing. This 0 not only a good work practice, it b a requirement of OSHA regulation 29CFR 1910.1001 (GK2XUD. Contact hdustrlal Hygiene and Toxicology for information an approved respirators. 4.1.2 OSHA regulation 1910.1001 contains explicit requirements and work practices which must be followed when the potential far ad>estos closure can occur. The regulation provides details on: respirator programs, change rooms and clothes lodcers, area and personal sampling requirements, caution signs and labels, house keeping, waste disposal, medical recordkeeping and -medical -examinations. This regulation must be consulted and followed. 4.1.3 Isolate the repair area to keep other employes as far as possible from the repair operation. The surfaces to be repaired must be wetted down where possible or treated with commercially available dust sigspressant to control dispersion of adsestos fibers. Wet methods ol du^t suppression are most effective in controlling exposure to airborne fibers. 4.1.4 Place plastic sheeting on the floor beneath the repair site so that all pieces of Insulation, however small, can be collected when finished. Pedestrian and vehicular traffic can redisperse asbestos Into the air if pieces are left on the floor. Pieces of equipment, structures, etcu, which are covered with friable a&estos material must be wetted down and must not be thrown or dropped during lemovaL 4.1.5 If It is necessary to sweep the adtestos, the floor must be wetted down to keep the fibers from becoming airborne. Approved vacuum cleaners must be used to clean the floor of any remaining dried a&estos dust and small pieces of material. Industrial Hygiene and Toxicology can recommend approved, highly efficient vacuum cleaners. 4.1.6 All waste, scrap, and debrb, as well as adbestos-cantaminated clothing, must be wetted and placed in sealed impermeable bags or containers for proper disposal. No asbestos-containing insulation should be placed in open trash containers or dumpsters. AU waste material containing adsestos or containers into which waste Is placed for disposal must be labeled In accordance with OSHA Standard 1910.1001 (GXzXiXli). See Section 4.4.6 for dlgtosal requirements. 4.1.7 Because asbestos fiber can be dispersed throughout adjacent areas by ventilation systems, air-supply fans In the vicinity of adbestos removal projects should be turned off; exhaust fans should be left on (unless these fans are part of an air recirculation system) to keep the area under negative pressure. Any grinding or cutting of adsestos containing material must be done with local exhaust ventilation which conforms to OSHA Standard 1910.1001.
