Mold Remediation Certification Practice Exam

If the team is under negative pressure, how should the pressure outside the containment be described?

1. Equal

2. Negative

3. Positive

4. Neutral

The correct answer is: Positive

When a team is working under negative pressure, it is important to maintain a controlled environment within the containment area to prevent the spread of mold spores and other contaminants. In this scenario, the pressure outside the containment should be described as positive. This positive pressure outside the containment helps ensure that air flows into the containment area rather than escaping to the outside environment, effectively reducing the risk of contamination spreading beyond the work area. The positive pressure outside acts as a barrier, preventing airborne contaminants from leaking out and also protecting occupants in the surrounding area. Maintaining this differential pressure is a critical aspect of effective mold remediation practices as it helps to secure both the safety of workers and the cleanliness of the surrounding environment.
