• A. Full Containment
• B. Fungi
• C. Hard Wall System
• D. Health Care

Answer: (A)

Controlling mold migration relies on choosing the right level of containment for the work area. When mold growth covers more than about 100 square feet and exposure is likely to be intense or long-term, a full containment approach is used. This means building a sealed enclosure around the work zone, using solid barriers or sturdy walls rather than just loose plastic, and maintaining negative air pressure inside the containment so air flows in rather than out. The setup typically includes controlled entry and exit (an airlock or decontamination area) and HEPA-filtered exhaust to prevent spores from spreading to the rest of the building. This robust barrier minimizes worker exposure and prevents mold spores from migrating beyond the work area during cleanup. The other options don’t describe this approach. Fungi refers to the organism itself, not how the area is protected. A hard wall system is a construction detail that could be part of containment but doesn’t in itself name the containment level. Health care is unrelated to containment strategies for mold.
