What is the recommended minimum pressure differential for poly?

• A. -0.01 inch of water gauge
• B. -0.02 inch of water gauge
• C. -0.03 inch of water gauge
• D. -0.04 inch of water gauge

Answer: (B)

The recommended minimum pressure differential for poly, particularly in the context of microbial remediation, is indeed -0.02 inch of water gauge. This pressure differential is crucial because it helps ensure that contaminated air or gases do not escape from the contained area, effectively managing the spread of potential contaminants. Maintaining this specific pressure differential creates a controlled environment where the airflow is directed inward, thereby providing negative pressure that minimizes the risk of cross-contamination. This is especially important in situations involving mold remediation or other microbial issues, as it prevents spores from traveling to other areas and contributing to further contamination. In practice, professionals rely on this standard to maintain safety and compliance with industry best practices, reinforcing the need for such a specified pressure to be upheld during remediation activities.
