What is required of the negative pressure in containment?

The requirement for negative pressure in containment primarily focuses on its role in preventing the migration of particulate material, particularly mold spores and other airborne contaminants, outside the controlled area. This is crucial during mold remediation efforts to ensure the safety of the surrounding environment. By maintaining a negative pressure, the containment effectively creates an airflow that draws air into the containment area rather than allowing it to escape. This containment strategy minimizes the risk of cross-contamination, protecting both workers and occupants in adjacent areas.

While ensuring sufficient airflow, adjustability, and continuous monitoring can be important aspects of a containment strategy, they do not directly address the principal safety concern of preventing the spread of contaminants. The main goal is to create a protective barrier that restricts the movement of potentially harmful particles, which makes the requirement for negative pressure to effectively prevent migration of particulate material a fundamental aspect of mold remediation practices.
