Which of the following is used to wet Asbestos Containing Material (ACM)?

Amended water is specifically formulated to enhance the effectiveness of wetting asbestos-containing material (ACM). It typically includes a surfactant or wetting agent, which reduces the surface tension of the water. This allows the water to penetrate the ACM more effectively, thereby minimizing the release of asbestos fibers during handling or removal. The use of amended water is crucial in asbestos abatement practices because it helps ensure safety by reducing airborne fibers that can pose health risks.

The other options do not provide the benefits that amended water offers when it comes to wetting ACM. While distilled water or plain water can be used to wet materials, they lack the added protective properties of surfactants that make amended water particularly effective for handling ACM safely. Chlorinated water is not appropriate because chlorine can have adverse effects on the materials or the environment without providing significant benefit for wetting ACM.
