a. Place six mil (0.006 inch) thick polyethylene sheeting under the asbestos-cement pipe to prevent soil contamination.

b. Adequately wet asbestos-cement pipe with amended water where cutting or breaking will occur.

c. Saw cutting of asbestos-cement pipe shall only be conducted with a HEPA-shrouded vacuum attachment or wet cutting equipment, unless it is conducted within a small enclosure that isolates the area in which the saw cutting is being conducted to prevent the release of asbestos fibers to ambient air.
