According to NYC regulations, what is the minimum requirement for overlapping floor plastic?

Explanation:
Creating a containment floor relies on a continuous dust barrier, and that hinges on how the plastic sheets meet. The floor plastic must be laid so that any seam where two sheets meet overlaps by a minimum amount and is securely taped. This overlap helps prevent fibers from escaping through gaps that could be created by butt joints or misaligned seams, which is why a six-inch overlap is required. Larger overlaps aren’t required as a minimum, so they aren’t the standard unless local conditions dictate it. In NYC regulations, the minimum overlap for floor plastic seams is six inches, with the seams taped to form a sealed, continuous barrier.
