What is the recommended thickness of plastic used for walls during asbestos work?

The recommended thickness of plastic used for walls during asbestos work is 4 mil. This thickness is considered suitable because it provides a balance of durability and effectiveness in preventing the release of asbestos fibers into the air. Using 4 mil plastic helps to contain any asbestos materials and protects workers from exposure, while also being lightweight enough for easy installation.

Thicker options, such as 6 mil or 8 mil plastic, could offer more durability but might not be necessary for all aspects of asbestos work, potentially leading to undue difficulty in handling or installation. Conversely, a thickness of 2 mil may not provide adequate protection, as it can be too flimsy to effectively contain asbestos materials, increasing the risk of fiber release during work. Thus, 4 mil is recommended to ensure effective containment and worker safety.
