Which of the following statements about asbestos removal is true?

The statement that asbestos must be kept wet and contained during removal is accurate due to the health risks associated with asbestos fibers. When asbestos-containing materials are disturbed, fibers can become airborne, posing significant inhalation risks to workers and anyone nearby. Keeping the materials wet minimizes the likelihood of these fibers becoming airborne, as moisture helps to encapsulate the fibers and reduces the potential for exposure. Additionally, containment strategies, such as using negative pressure enclosures and proper waste disposal methods, ensure that any released fibers do not migrate to other areas, protecting both the workers and the surrounding environment.

Other approaches mentioned in the incorrect answers would not prioritize safety effectively. For instance, dropping asbestos on the ground, even if wet, is not a safe practice as it could still lead to exposure or improper disposal. Ensuring materials remain dry would actually increase the risk of fibers becoming airborne. Lastly, while controlling airflow may seem beneficial, using fans to manage airborne fibers can actually exacerbate the problem by dispersing them further rather than containing them. This is why the emphasis on keeping asbestos wet and contained is crucial during the removal process.
