What is an example of primary engineering control in hazardous drug compounding?

In the context of hazardous drug compounding, the primary engineering control refers to the device or system that provides a controlled environment for compounding. A clean room is designed to minimize contamination and is a critical component in maintaining sterile conditions while handling hazardous materials.

The clean room functions to provide a physical barrier with controlled airflow and filtration systems designed to protect both the products being compounded and the individuals compounding them. It ensures that the environment meets proper standards for air cleanliness, which is essential when dealing with hazardous drugs that can pose a risk to health if incorrectly handled or if contaminants are introduced.

While buffer areas, pass-through chambers, and storage areas all play important roles in the overall compounding process, they do not serve as the primary engineering control. The buffer area is typically where the actual compounding takes place and is designed to maintain the sterile environment, but it is not classified as primary engineering control by itself. Similarly, pass-through chambers are used to facilitate the transfer of materials without compromising the sterile environment, and storage areas are designated for the proper holding of compounded products and raw materials, but they do not actively control the environment for compounding activities.
