Define positive pressure in a space?

Positive pressure in a space refers to a condition where the amount of air being supplied to that space exceeds the amount of air being removed. This creates an environment where the air pressure inside the space is higher than the air pressure outside it. As a result, this positive pressure can help prevent contaminants or pollutants from entering the area, making it particularly useful in settings that require a sterile environment or where microbial remediation is taking place.

In scenarios related to microbial remediation, maintaining positive pressure can help ensure that the air quality remains clean and that any potentially harmful airborne contaminants are kept out of the space being treated. It is a critical aspect of controlling environmental conditions to promote safe and effective cleanup processes.

The other options describe different air pressure scenarios. When less air is supplied than taken out, it indicates a negative pressure situation, leading to potential contaminants being drawn into the space. Balanced air flow means there is no net gain or loss of air pressure, while creating a vacuum refers to the condition where air pressure inside is lower than outside, which is the opposite of positive pressure. Understanding these distinctions is essential for effectively managing indoor air quality and creating an appropriate environment for microbial remediation efforts.
