Basic Cleanroom Gowning Procedure (Non-sterile Cleanrooms)

What is a Cleanroom?

Cleanrooms are typically used in scientific research and manufacturing to provide a controlled environment for handling sensitive components and samples. Cleanrooms are constructed in a way to minimize particles from being introduced, generated or retained inside the room. Depending on the cleanroom classification and application, the gowning procedure may vary. However, the following sequence is basically the same.

The higher the level of cleanliness, the lower the particles inside the room. Cleanrooms are typically classified as ISO 5 or ISO 6. Click here to view Cleanroom Classification list.

The largest percent of contributors to contamination within a clean room are people. Even the cleanest of people are naturally contaminated. Our bodies are natural host to unwanted bacteria, along with the shedding of skin cells, hair and exhale of bio-organisms. A well designed gowning room and strict gowning procedure must be followed in order to maintain a cleanliness classification. We will be covering the procedures personnel should follow to get cleanroom ready and some of the Cleatech gowning equipment that supports the gowning protocol.
