The document outlines cleanroom rules and practices that personnel should follow to minimize contamination. It states that cleanroom employees should be neat, clean and in good health. They must also have a minimum education level and understand aseptic techniques. Strict rules are outlined, including washing hands before entry, slow movement, limiting talking and activities that increase particles, and not bringing in unauthorized items. Personnel are instructed to avoid interrupting airflow, touching products directly and exposing them unnecessarily. Failure to follow the rules could lead to increased contamination from people, who are the main source of particles in cleanrooms.
