Remove visible accumulations of asbestos material and debris. Wet clean all surfaces within the work area.
Remove the cleaned outer layer of plastic from walls and floors. The windows, doors, and HVAC vents shall remain sealed and any HEPA filtration negative air pressure systems and decontamination enclosure systems shall remain in service.
After cleaning the work area, wait at least 24 hours to allow for the settlement of dust, and again wet clean or clean with HEPA vacuum equipment all surfaces in the work area.

Air monitoring volumes shall be sufficient to provide a detection limit of 0.01 or less fibers/cc of air.
Areas which do not comply with the Standard for Cleaning for Initial Clearance shall continue to be cleaned by and at the contractor's expense until the specified Standard of Cleaning is achieved as evidenced by results of air testing as previously specified.
Upon successful compliance with the Standard of Cleaning for Initial Clearance, mandatory respiratory protection for workers engaged in respray or finishing work in the work area may be waived at the discretion of the contractor. After initial clearance, the final layer of plastic may be removed by workers with proper respiratory protection. However, controls established in 188.8.131.52 may not be removed at this point.
At the request of the asbestos abatement supervisor, The Director of Industrial Hygiene will perform a reoccupancy visual inspection of the work area. Evidence of asbestos contamination identified during the inspection will necessitate further cleaning as heretofore specified. When the work area passes The Director of Industrial Hygiene's reoccupancy inspection, controls established in 184.108.40.206 will be removed. Additional air monitoring shall be performed by The Director of Industrial Hygiene as a part of their occupancy clearance inspection a final clearance level of 0.005 fibers/cc of air or less shall be obtained before reoccupancy.
