What is a common effect of improper encapsulation of ACM?

Improper encapsulation of asbestos-containing material (ACM) leads to a release of asbestos fibers into the air, which poses significant health risks to individuals exposed to these fibers. Encapsulation is meant to control the release of asbestos by sealing it and preventing airborne exposure. When encapsulation is done inadequately, the integrity of the seal can be compromised, resulting in fibers becoming airborne and increasing the likelihood of inhalation, which can cause severe respiratory diseases, including asbestosis and mesothelioma.

The other options do not accurately reflect the consequences of improper encapsulation. For example, the idea that there would be an increase in aesthetic value or enhanced safety is misleading, as the health hazards associated with improperly handled ACM can compromise both the appearance and safety of a building. Additionally, a decrease in structural integrity, while a potential concern in other contexts, is not a direct consequence of improper encapsulation, which primarily affects the containment of asbestos fibers.
