Which zone is described as normally free of contamination but at risk for cross-contamination?

The correct choice refers to Zone 2, which is typically described as an area that is expected to be free from contamination under normal conditions. However, it's important to recognize that even in this zone, there is a risk for cross-contamination. This can occur due to various factors, such as personnel movement, improper handling of materials, or inadequate cleaning protocols.

Zone 2 is strategically designed to limit contamination, often serving as a buffer between areas that may harbor contaminants and more sensitive or sterile environments. The awareness of potential cross-contamination in this zone underscores the necessity for rigorous hygiene practices and careful management of workflows. Maintaining the integrity of Zone 2 is crucial for safeguarding the overall cleanliness of adjacent zones where higher levels of contamination control are required.

In contrast to this, other zones, which you may be considering, either have higher risks of contamination or are intended for completely different functions that do not focus on mitigating cross-contamination in the same manner as Zone 2.
