What type of containment is appropriate for small areas of microbial contamination?

Source containment is specifically designed for managing small areas of microbial contamination. This method focuses on controlling the area where contamination exists, preventing spores and microbial agents from spreading to uncontaminated areas. In this approach, barriers or physical enclosures are typically established to keep contamination localized.

The effectiveness of source containment lies in its ability to provide a controlled environment for remediation efforts without the need for more extensive containment strategies that are warranted for larger areas or more severe contamination events. This method allows for efficient cleaning, removal, and remediation processes while minimizing disruption to surrounding environments.

In contrast, full-scale containment involves creating larger, more elaborate containment areas, often requiring more resources and potentially impacting a wider area than necessary for small contamination issues. Negative pressure containment increases air flow towards the contaminated area to prevent the spread but is typically reserved for larger projects. Barrier containment focuses on physical barriers but may not always provide the localized control necessary for small areas. Thus, for small areas of microbial contamination, source containment is the most appropriate choice.
