Asbestos Contractor/Supervisor Practice Exam

What is one disadvantage of enclosure for asbestos?

1. It creates a more expensive solution

2. It is initially cheaper than removal

3. It does not provide long-term safety

4. It requires more extensive environmental controls

The correct answer is: It is initially cheaper than removal

The reasoning behind selecting that option as the correct answer lies in the understanding of how enclosure functions as a method for managing asbestos hazards. Enclosure allows for the physical containment of asbestos-containing materials, which can be a temporary solution that minimizes exposure risks. This method often results in lower upfront costs compared to complete removal of the asbestos, which involves comprehensive demolition work, waste disposal, and potential renovations to restore affected areas. However, while this approach may be economically favorable at the outset, it does not eliminate the underlying issues associated with asbestos, as the material remains in place, potentially leading to future safety concerns. The limitations of enclosure include the necessity for ongoing monitoring, potential degradation of the enclosure over time, and the possibility of disturbed materials, which can release fibers into the environment. Other choices may suggest various critical aspects of enclosure, but fundamentally, the immediate financial benefits associated with enclosure (compared to removal) are central to the understanding of its disadvantages long-term. This choice effectively highlights the balance between cost considerations and the adequacy of safety measures in managing asbestos risks.
