What does "containment" refer to in mold remediation?

Containment refers to the process of isolating the affected area during mold remediation. This is a critical step to prevent the spread of mold spores to unaffected areas of a building while remediation is underway. By establishing physical barriers, such as plastic sheeting and negative air pressure, the remediation team can limit exposure and ensure that mold spores do not migrate into clean spaces, protecting occupants and preventing the growth of new colonies.

The concept of containment emphasizes the importance of controlling the environment surrounding the mold-affected area. It allows for safe removal and cleaning procedures to commence without risking cross-contamination.

In contrast, the other processes mentioned in the other choices don't align with what containment entails. Removing all mold, cleaning surfaces, and testing air quality are all vital components of mold remediation, but they occur after containment has been established or are part of broader remediation efforts, rather than the process of isolating the affected area itself.
