3.2.1 Prepare site (see section 3.1)

3.2.2 Spray asbestos material with amended water, using spray equipment capable of providing a "mist" application to reduce the release of fibers. Saturate the material sufficiently to wet it to the substrate without causing excess dripping. Spray the asbestos material repeatedly during work process to maintain wet condition and to minimum asbestos fiber dispersion.

3.2.3 In order to maintain indoor asbestos concentrations at a minimum, the saturated asbestos must be removed in manageable section. Material shall not be allowed to dry out.

Sealed drums and all equipment used in the work area shall be included in the cleanup and shall be removed from work areas, via the Equipment Decontamination Enclosure at an appropriate time in the cleaning sequence.

If the building owner finds visible accumulations of dust in the work area, the contractor shall repeat the wet cleaning until the work area is in compliance, at the contractor's expense.


Upon notice from contractor that work areas and all other contaminated and cleaned areas area ready for initial clearance testing. The Director of Industrial Hygiene shall test for the Standard of Cleaning for Initial Clearance of 0.01 or less fibers/cc of air. 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 may not be removed at this point.

Reoccupancy Clearance

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 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.


When cleanup is complete.
