What material should be used to isolate the work area from occupied spaces?

Using plastic sheeting to isolate the work area from occupied spaces is effective for several reasons. Plastic sheeting serves as a barrier that can prevent the spread of mold spores and contaminants from an area where remediation or work is being carried out. This material is lightweight, easy to handle, and can be sealed tightly to create a secure boundary, minimizing the risk of exposure to mold or other harmful substances.

Additionally, plastic sheeting can be easily adhered to surfaces and is impermeable to moisture, which is crucial in preventing mold spores from escaping into occupied areas. Its transparency allows for visibility, enabling workers to monitor the area while maintaining a barrier.

In contrast, materials like cardboard, wood panels, and metal sheets are less effective. Cardboard can absorb moisture, which might promote mold growth, while wood panels might also hold moisture and potentially harbor mold. Metal sheets, while effective in some specific applications, are heavy and can be cumbersome to install and remove, and they might not provide the necessary flexibility or ability to create an airtight seal as plastic sheeting does.
