When setting up negative pressure containments, what is a key consideration regarding plastic sheeting?

When setting up negative pressure containments, creating a moisture barrier is essential to prevent the escape of moisture and contaminants into unaffected areas. A moisture barrier ensures that any water vapor generated during remediation does not permeate through to other areas, which could facilitate further microbial growth or damage. It plays a crucial role in maintaining control over the work environment, helping to contain contaminants while also preventing the growth of mold and other microbes due to increased moisture levels.

While double-layering can enhance the integrity of the containment and transparency might be a consideration for visibility, the primary focus of the plastic sheeting in this context is its effectiveness in preventing moisture from escaping. The lightweight aspect, while potentially beneficial for ease of handling and installation, does not directly address the functional requirement of controlling moisture, which is the key concern in microbial remediation scenarios.
