What must be done to the surfaces of fixed objects in the work area before starting the abatement process?

Before commencing the abatement process for asbestos, it is essential to cover the surfaces of fixed objects in the work area with plastic sheeting. This procedure serves multiple vital functions.

First, it acts as a containment measure, preventing the spread of asbestos fibers throughout the environment during the removal or remediation activities. Asbestos is hazardous when disturbed, and enclosing items in plastic sheeting helps to mitigate the risk of contamination to both the work area and adjacent spaces.

Second, covering surfaces protects them from any debris or residual asbestos that may result from the abatement work. This ensures that the fixed objects can remain intact and untainted by contaminants, which could otherwise lead to more extensive cleaning or removal efforts.

In contrast, other options like removing items from the site can be impractical and time-consuming, while leaving items as they are provides no safeguarding against potential asbestos exposure. Sanding down fixed surfaces could further disturb asbestos materials, increasing the risk of fiber release. Therefore, the best practice involves securing the area properly by utilizing plastic sheeting to effectively manage any hazards during the abatement process.
