What is a local containment?

A local containment refers to the practice of creating a specific area where microbial remediation work can take place while limiting the spread of contaminants to other areas. This is typically done using materials such as polyethylene sheeting (poly), which acts as a barrier. The purpose of local containment is to ensure that any potential contaminants, such as mold spores or bacteria, are kept within a controlled environment to protect other parts of a structure from exposure.

Creating an enclosure with poly accomplishes several objectives: it minimizes the risk of cross-contamination, helps manage particulate matter, and allows for effective air filtration and vacuum systems to work efficiently within that contained space. The ability to control airflow and site conditions inside this enclosure is crucial for effective remediation and health safety.

In contrast, the other options describe situations that either do not restrict airflow or are unrelated to microbial remediation practices, making them less suitable definitions for a local containment.
