In ICR-56, how far must poly cover the ceiling and down the walls during work area preparation?

In ICR-56, it is specified that the poly sheeting must cover the ceiling and extend down the walls by a minimum of 12 inches during work area preparation. This requirement serves a crucial function in containing asbestos fibers and preventing them from escaping the work area. By extending the poly sheeting down the walls, it helps ensure that any debris or airborne particles that may be disturbed during the handling of asbestos are captured and do not mix with the surrounding environment. This protective measure also reinforces the overall safety protocols established for asbestos abatement processes, aligning with regulatory standards for maintaining a safe and controlled work environment.
