The purpose of a containment plan in a duct cleaning scope is to prevent dust and debris from migrating beyond the cleaning area. By setting up physical barriers, negative pressure, and designated entry/exit zones, it keeps the work confined, protecting occupants, furnishings, and other spaces from contamination and reducing the risk of recontamination of cleaned areas. A solid containment plan also supports safety, regulatory compliance, and a thorough, orderly cleanup by outlining how the work zone is maintained throughout the process. The other options miss the goal: the color of tape is irrelevant; shortening the work at safety’s expense compromises safety; and maximizing debris spread is the opposite of containment.
