What type of pressure is required to maintain the containment during mold remediation?

1. Positive pressure

2. Negative pressure

3. Neutral pressure

4. Vacuum pressure

The correct answer is: Negative pressure

In mold remediation, maintaining negative pressure within the containment area is crucial for safety and effectiveness. Negative pressure means that the air pressure inside the containment is lower than the air pressure outside it. This setup ensures that any mold spores or contaminants that may be disturbed during the remediation process are contained and do not escape into the surrounding environment. By creating negative pressure, the airflow is directed into the containment area rather than out of it, effectively minimizing the risk of spreading mold spores to other rooms or areas. The use of proper air filtration systems, such as HEPA filters, in conjunction with this pressure allows for the effective removal of airborne particulates, further enhancing safety. In contrast, options like positive pressure would push air out of the containment, risking the spread of mold spores, while neutral pressure would not provide any significant control over air movement. Vacuum pressure, although it denotes a low-pressure environment, does not specifically align with the context of mold containment used in remediation practices. Thus, negative pressure is the most effective method to ensure containment during mold remediation activities.
