Which piece of equipment provides ISO class 5 air quality for sterile compounding?

The correct answer indicates that the Primary Engineering Control (PEC) is the piece of equipment that provides ISO class 5 air quality for sterile compounding. PECs are critical components in the sterile compounding area as they create a controlled environment that filters and circulates air to maintain a very low level of airborne particles, which is essential for ensuring the safety and sterility of the compounded products.

In an ISO class 5 environment, the maximum allowable level of particles is very low, which is crucial for preventing contamination during the preparation of sterile pharmaceuticals. PECs achieve this by using high-efficiency particulate air (HEPA) filters in combination with appropriate airflow systems that minimize particulate exposure and maintain the necessary air quality.

While the other options mentioned, like Secondary Engineering Controls (SEC) and Cleanroom Suites, are integral to the overall sterile compounding environment and help maintain cleanliness and reduce contamination, they do not specifically provide the critical ISO class 5 air quality directly. For instance, an SEC is designed to support the PEC and provide additional protection but operates in a different capacity that does not directly manipulate air quality to the same stringent levels required for sterile compounding. Meanwhile, a Cleanroom Suite encompasses multiple areas, including the PEC and SEC, but does not
