How far up must wall, floor, and ceiling poly sheeting be hung beyond wall/floor and wall/ceiling joints?

The correct answer indicates that the poly sheeting must be hung 12 inches beyond wall/floor and wall/ceiling joints. This requirement is established to ensure a secure and effective barrier against the release of asbestos fibers in areas where renovation or demolition activities take place. The 12-inch extension creates a sufficient overlap that helps contain potential asbestos particles and minimizes the risk of exposure during cleanup or remediation processes.

By extending the sheeting adequately beyond these joints, it provides a more comprehensive seal that can effectively prevent any contamination and maintain safety for workers and occupants in the area. Proper measures are essential for adhering to asbestos regulations, emphasizing the importance of following these specific distance requirements to achieve optimal containment and safety.
