3.02 ACCETPABLE REMOVAL METHODS

A. Use wet removal techniques for all ACM removal

1. Thoroughly wet, to satisfaction of Owner Representative, ACM to be removed prior to stripping and/or tooling to reduce fiber dispersal into the air. Accomplish wetting by a fine spray (mist) of amended water or removal encapsulant. Saturate material sufficiently to wet to the substrate without causing excess dripping. Allow time for water or removal encapsulant to penetrate material thoroughly. If amended water is used, spray material repeatedly during the work process to maintain a continuously wet condition. If a removal encapsulant is used, apply in strict accordance with manufacturer's written instructions. Where necessary, carefully strip away while simultaneously spraying amended water or removal encapsulant on the installation to minimize dispersal of asbestos fibers into the air.

2. Mist work area continuously with amended water whenever necessary to reduce airborne fiber levels.

3. Remove saturated ACM in small sections. Do not allow material to dry out. As it is removed, simultaneously pack material while still wet into asbestos disposal bags. Twist neck of bags, bend over and seal with minimum three (3) wraps of duct tape. Clean outside and move to wash down station adjacent to material decontamination unit. Waste shall be double bagged or bagged and placed in a second impermeable container (i.e., cardboard drum).
