Which category is least suspected of releasing asbestos fibers into the air?

The category of miscellaneous products is considered least suspected of releasing asbestos fibers into the air because these products typically do not serve a primary function in environments where asbestos is known to be a risk. Miscellaneous products can encompass various items used in construction or manufacturing, many of which are less likely to contain significant amounts of asbestos or be subject to disturbance that would release fibers.

Insulation materials, flooring materials, and roofing materials are often more directly associated with asbestos because they were commonly manufactured with the mineral due to its fire-resistant properties and insulation capabilities. Disturbances to these products—such as renovations, wear over time, or demolition—can lead to the release of harmful asbestos fibers. In contrast, miscellaneous products might include items that either do not have asbestos as a component or are used in a way that does not cause fiber release, making them less of a concern in relation to air contamination.
