# 454 CMR: DEPARTMENT OF LABOR STANDARDS 28.10: continued 4. Decontamination of Personnel Required. No abatement personnel may leave the Work Area without first decontaminating their persons by showering, wet washing or HEPA vacuuming to remove all asbestos debris. 5. Location of Decontamination Facilities. Where feasible, decontamination facilities must be contiguous with the Work Area. Where this is not feasible, the decontamination facility must be sited as closely as possible to the Work Area. Persons using such a remotely-sited decontamination facility must remove visible debris from their persons by HEPA vacuuming prior to donning clean disposable coveralls while still in the Work Area, and then proceed directly to the remote decontamination system to shower and change clothes. 6. Equipment Decontamination. No equipment, supplies, or materials (except properly containerized waste material) must be removed from an asbestos Work Area, unless such equipment, supplies or materials have been thoroughly cleaned free of asbestos debris. Where decontamination is not feasible, such materials must be wrapped in a minimum of two layers of six-mil polyethylene sheeting with all joints, seams and overlaps sealed with tape or containerized in a metal, plastic or fiber drum with a locking lid. Said wrapped equipment, supplies or materials must be labeled as being asbestos-contaminated prior to removal from the Work Area. HEPA vacuums must be emptied of contents prior to removal from the Work Area. Air filtration devices must have used pre-filters and intermediate filters removed and replaced with fresh filters prior to removal from the Work Area. Used HEPA filters, intermediate and pre-filters must be disposed of as asbestos waste. 7. Requirements for Clean Room. A clean area or room (clean room) must be provided with lockers or other appropriate containers for the storage of each worker's clothes and personal items. A trash container for non-contaminated waste must…

# 454 CMR: DEPARTMENT OF LABOR STANDARDS 28.10: continued (d) Work Procedures. 1. Wetting of Asbestos. Prior to removal, ACM must be adequately wetted with Amended Water. Water must not be applied in amounts that will cause run off or leakage of the water from the Work Area. Once removed, ACM must be kept wet until containerized pursuant to 454 CMR 28.10(4)(d)2. and 310 CMR 7.15: U Asbestos. 2. Containerization of Asbestos. Removed ACM and asbestos-contaminated debris within the Work Area must be promptly cleaned up and containerized. Containerized ACM must be removed from the Work Area at least once each working shift. Waste not containing components with sharp edges must be containerized in two plastic bags (six- mil minimum thickness each bag, one inside the other) or in metal, plastic or fiber drums with locking lids. ACM with sharp edged components must be contained in leak-proof metal, plastic or plastic-lined, drums or boxes. Large components removed intact must be wrapped in a minimum of two layers of six-mil polyethylene sheeting with all joints and seams sealed with duct tape, and labeled as ACM prior to removal from the contained Work Area. 3. Material Deposition. ACM must not be dropped or thrown from heights greater than 15 feet. Asbestos-containing asphaltic shingles or felts shall not be dropped or thrown to the ground. Unless the material is carried or passed to the ground by hand, it shall be lowered to the ground by crane or hoist or transferred in dust-tight chutes. 4. Enclosure. Where ACM is enclosed during an Asbestos Response Action, the following provisions must also apply: a. Enclosures over pipes, ducts, tanks, boilers or other objects must be labeled as containing ACM and identified on building records. b. Enclosure systems must be constructed to be dust tight. 5. Encapsulation. Encapsulants must not be applied to severely damaged or deteriorating ACM. 6. Demolition. The notification provisions 454 CMR 28.09 and…

# 454 CMR: DEPARTMENT OF LABOR STANDARDS 28.10: continued (g) Any ACM that has been exposed as result of the glove bag operation must be suitably removed, encapsulated or enclosed so as to prevent the leakage of asbestos fibers prior to the removal of the glove bag. (h) All surfaces from which ACM has been removed inside the glove bag and the upper portions of the glove bag itself must be cleaned free of visible debris prior to removal of the glove bag. (i) Debris must be isolated in the bottom of the glove bag by twisting the bag so as to form a closure in the middle. This closure must then be taped around with duct tape or equivalent material. Air in the glove bag must be exhausted with a HEPA vacuum cleaner prior to its removal. (j) Following removal from the structure, the glove bag and its contents must be containerized in accordance with 454 CMR 28.10(4)(d)2. and disposed of in accordance with 454 CMR 28.10(8)(a). (6) Cleanup. Following an Asbestos Response Action, the Asbestos Contractor or entity performing the work must decontaminate all contaminated surfaces within the Work Area using HEPA vacuuming or wet cleaning techniques, including surfaces contaminated prior to the Asbestos Response Action. All equipment and materials used and all surfaces from which ACM has been removed must be decontaminated. If asbestos materials were not substantially intact at time of removal; an inch of soil must be removed from dirt floors and disposed of as asbestos containing waste. All cleanup materials must be disposed of as asbestos waste. Cleanup must be to the level of no visible debris. (7) Clearance Monitoring. Following the cleanup required by 454 CMR 28.10(6), the facility owner, Asbestos Contractor, entity conducting the Asbestos Response Action, or the Asbestos Project Monitor employed to oversee the work operation must ensure that the clearance monitoring requirements of 454 CMR 28.10(4)(9), (10) and (11) are met. Until these conditions are achieved al…

# 454 CMR: DEPARTMENT OF LABOR STANDARDS 28.11: continued (c) Notification Requirements. Persons or entities carrying out Asbestos Operations and Maintenance Projects shall comply with the applicable notification requirements of 454 CMR 28.09 and 28.11. (3) General Work Practice Requirements. Persons or entities carrying out, or having supervisory authority over Asbestos Operations and Maintenance Projects shall ensure that the work practice requirements of 454 CMR 28.11(3)(a) through (3)(k) are met. Persons or entities carrying out, or having supervisory authority over, Asbestos Operations and Maintenance Projects involving the removal or disturbance of: vinyl asbestos tile; sheet asbestos-containing floor coverings; asbestos-containing floor mastic; asbestos-containing gypsum board and joint compounds; shall additionally comply with the applicable requirements of 454 CMR 28.11(4) through (6). (a) All persons not directly involved in the work shall be excluded from the Work Area for the duration of the project by physical barriers or other appropriate means. (b) Dust tight barriers shall be constructed, as necessary, to ensure that asbestos-containing dust released during work activities is contained within the Work Area. Glove bags and prefabricated mini-enclosures are permitted in place of constructed barriers. (c) Sources of electric power for power tools or other equipment used in the Work Area shall be ground fault circuit interrupter (GFCI) protected. (d) ACM shall be wet with Amended Water before it is disturbed, and it shall be kept wet throughout the work operation until properly containerized. In accordance with 454 CMR 28.10(4)(d)1., an exception to the wetting requirement may be granted by the Director, where wetting of Asbestos-containing Material would create slipping, electrical or other safety hazards. (e) Where ACM is being removed, it shall be removed in an intact state to the greatest feasible extent. (f) Where power tools are use…
