Sterile garments can be free from contaminants, but not particulates. They can still introduce particles into your cleanroom, although they would likely be sterile particles. Clean and sterile garments, on the other hand, have been cleaned for particulate removal as well as sterilized. These are often called “lint-free.”
Training your employees to follow your cleanroom gowning protocol is always the first step in good management. But ensuring strict compliance is difficult to enforce. Human nature slides us towards the path of least resistance, so we must constantly keep these garmenting standards in front of our employees.
