What is the primary function of a wetting agent in asbestos removal?

The primary function of a wetting agent in asbestos removal is to reduce airborne dust. When asbestos-containing materials are disturbed, fine, airborne fibers can be released into the environment, posing a serious health risk. Wetting agents are added to water to lower its surface tension, allowing it to spread more effectively over surfaces. This helps to saturate asbestos materials, preventing fibers from becoming airborne during the removal process. By effectively controlling dust generation, wetting agents are essential in maintaining a safer work environment for those involved in asbestos abatement.

While other options mention enhancing fiber strength or reducing toxicity, they do not align with the specific role of a wetting agent in controlling dust, which is crucial during the removal process to minimize exposure to hazardous asbestos fibers.
