Personnel of other trades not engaged in the removal and demolition of asbestos containing materials shall not be exposed at any time to airborne concentrations of asbestos unless all the personnel protection provisions of this specification are complied with by the trade personnel. Shut down the heating, ventilating, and air conditioning system in the area of work, and seal the openings to the system prior to the commencement of asbestos work. Disconnect electrical service when wet removal is performed and provide temporary electrical service with verifiable ground fault circuit interrupter (GFCI) protection prior to the use of any water. If an asbestos fiber release or spill occurs outside the asbestos control area, stop work immediately, correct the condition to the satisfaction of the Owner or their Representative including clearance sampling, prior to resuming work.

B. Protection of Existing Work to Remain

Perform work without damage or contamination of adjacent work. Where such work is damaged or contaminated as verified by the Owner's Representative using visual inspection or sample analysis, it shall be restored to its original condition or decontaminated by the contractor at no expense to the Owner as deemed appropriate by the Owner' Representative. This includes inadvertent spill of dirt, dust, or debris in which it is reasonable to conclude that asbestos may exist. When these spills occur, stop work immediately. Then clean up the spill at the Contractor's expense. When satisfactory visual inspection and air sampling results are obtained from the Owner's Representative work may proceed at the discretion of the Owner's Representative.

C. Furnishing

The Owner and General Contractor will coordinate any appropriate furniture and equipment removal (i.e. desks, chairs, tables, electronics, moveable lockers, etc.) before asbestos work begins.

D. Pre-cleaning

Wet wipe and HEPA vacuum all surfaces potentially contaminated with asbestos prior to establishment of an enclosure.

E. Enclosure Negative pressure enclosures for friable (regulated) removals shall consist of critical barriers, wall, floor and ceiling polyethylene sheeting, where applicable. All polyethylene sheeting used shall be fire retardant. Surfaces scheduled for removal do not require polyethylene coverings.

Contiguous five-stage decontamination unit shall consist of a workroom, airlock, shower with hot and cold water, airlock and clean room. Critical barriers and the decontamination coverings shall be constructed of a minimum 2-layer 6-mil polyethylene. Wall and ceiling coverings, where applicable, shall be constructed of a minimum 4-mil polyethylene. Floor coverings shall consist of two layers of 6-mil polyethylene sheeting. Negative pressure shall be established, maintained and recorded as stated herein. Provide local exhaust system in all asbestos control areas. Openings will be allowed in enclosures of asbestos control areas only for personnel and equipment entry and exit, the supply and exhaust of air for the local exhaust system and the removal of properly containerized asbestos containing materials. Replace local exhaust system filters as required to maintain the efficiency of the system. Establish designated limits for the asbestos work area with the use of continuous barriers and maintain all other requirements for asbestos control areas. If the quantity of airborne asbestos fibers monitored at the designated limits at any time exceed 0.01 fibers per cubic centimeter via Phase Contrast Microscopy (NIOSH 582), stop work, evacuate personnel in adjacent areas or provide personnel with approved protective equipment at the discretion of the Owner's Representative. If adjacent areas are contaminated as determined by the Owner's Representative, clean the contaminated area, monitor and visually inspect the area as specified herein. The glue, tape, fasteners, spray-glue, etc. used to secure polyethylene sheeting shall not leave a residue upon removal, and the Contractor is responsible for damage to substrate or paint finishes resulting from removal of such products.

F. Asbestos Handling Procedures

Remove material, allow for minimal accumulations and immediately place in 6-mil polyethylene disposal bags. No waste shall remain in the containment at the end of the day unless properly sealed in disposal bags or equivalent.

G. Site Inspection While performing asbestos removal work, the Contractor shall be subject to on site inspection by the Owner's Representative. If the work is in violation of specification requirements, the Owner's Representative may issue a stop work order to be in effect immediately and until deficiencies are corrected. Standby time and associated expenses shall be the responsibility of the Contractor.

H. Air Monitoring

The Owner’s IH shall perform air monitoring as required by the SCDES Regulations 61-86.1.

The air monitoring shall be performed by an individual licensed by the SCDES as an Air Sampler and the analysis for this project shall be by Phase Contrast Microscopy (PCM) NIOSH 7400 and Transmission Electron Microscopy (TEM) in accordance with SCDES Regulations 61-86.1.

I. Clean-up and Disposal

1. Housekeeping Essential parts of asbestos dust control are housekeeping and clean-up procedures.

Maintain surfaces of the asbestos control area free of accumulations of asbestos fibers.

Give meticulous attention to restricting the spread of dust and debris; keep waste from being distributed over the general area. Use HEPA filtered vacuum cleaners.

2. Final Inspection and Air Clearance

i. When asbestos removal is complete, all asbestos waste is removed from the work-site, and final clean-up is completed, the Owner's IH and the Contractor’s SCDES licensed Supervisor will visually inspect all surfaces within the work area for residual material or accumulated dust or debris. The Contractor shall re-clean all areas showing dust or residual materials. Encapsulant may not be applied or any of the work area components dismantled until an acceptable final inspection is conducted. Following an acceptable final inspection, the clearance air test shall be conducted while the work area remains under negative pressure and only the critical barriers and decontamination unit remain. The work area shall be maintained and not dismantled until the IH notifies the Contractor of acceptable air concentrations.

ii. Clearance testing shall be performed for friable (regulated) ACMs following a visual inspection of the work area by the Owner’s IH and the site supervisor for the Contractor. Clearance testing shall not be performed until all visible debris is removed, the area dry, and polyethylene removed with exception to the critical barriers. Air clearance at YWC-07 Whitemarsh House shall be performed via TEM in accordance with the SCDES Regulations 61-86.1. Clearance criteria for TEM analysis is a mean of 70 structures per square millimeter for a set of five samples.

Air clearance at YWC-13 Office/Residence shall be performed via PCM in accordance with the SCDES Regulations 61-86.1. Clearance criteria for PCM is

4. Disposal of Asbestos

i. Procedure for Disposal Collect asbestos waste, asbestos contaminated water, scrap, debris, bags, containers, equipment, and asbestos contaminated clothing which may produce airborne concentrations of asbestos fibers and place in sealed fireproof, waterproof, non-returnable containers (e.g. double 6-mil bags, cartons, drums or cans). Wastes within the containers must be wetted to ensure security of the material in case of container breaching. Affix a warning and Department of Transportation (DOT) label to each bag or use at least 6-mil thick bags with the approved warnings and DOT labeling reprinted on the bag. The name of the waste generator and the location at which the waste was generated shall be clearly indicated on the outside of each container. Dispose of waste asbestos material at a SCDES approved asbestos landfill. For temporary storage, store sealed impermeable bags in asbestos metal dumpsters or containers. An area for interim storage of asbestos waste-containing metal dumpster or container will be assigned by the Owner's Representative. Metal dumpsters or containers in which asbestos waste is temporarily stored at the abatement site shall be lined with 6-mil polyethylene sheeting to prevent contamination and shall have doors and tops. The doors and tops shall be closed and locked except during loading or unloading asbestos waste.

Procedure for hauling and disposal shall comply with 40 CFR 61, SUBPART M, and state, regional and local standards. Sealed plastic bags may be dumped from metal dumpsters or containers into the burial site unless the bags have been broken or aged. Unloading of metal dumpsters or containers by tipping or tilting is permitted without re-inspecting individual bags or provided there are no visible emissions. Following the removal of all containerized waste, polyethylene sheeting shall be removed and discarded in bags or drums along with contaminated cleaning materials and protective clothing.

ii. After asbestos waste has been unloaded, the truck cargo area or waste container, including the floor, walls and ceiling, shall be decontaminated using wet methods or a vacuum equipped with a HEPA filter until no visible residue remains.
