This document describes best practice rules and behaviors for the Class 1000 cleanroom. Please contact the cleanroom supervisor with any questions or suggestions you might have regarding these recommendations.
- Do not bring food or drinks in the gowning or cleanroom areas. Do not chew gum or tobacco.
- Do not wear cleanroom garments outside the cleanroom/gowning room areas. The only time one should exit the cleanroom/gowning area in full cleanroom apparel is in case of an emergency (e.g., major chemical spill, gas leak, etc.)
- In the gowning room, do not step in the “clean” area while wearing street apparel. Do not stand on the dirtier, “street” side of the bench in cleanroom coverall.
- Do not wear dirty or torn cleanroom garments in the cleanroom.
- Do not unzip cleanroom coverall to retrieve items from beneath the cleanroom garment (e.g., cell phone, pen). Return to the gowning room before unzipping coverall to retrieve item (subsequent item wipe-down and glove exchange might be necessary).
- Do not sit on the gowning bench while wearing cleanroom coverall.
- Do not write on gloves or cleanroom garments.
- Replace cleanroom coverall after 10 days of usage (or earlier if torn or damaged).
- Do not remove gloves at any time in cleanroom. In particular, do not lower glove cuffs and raise coverall sleeves to check watch.
- Do not touch, rub or scratch skin, hair or eyes with gloves. If you do, replace your gloves.
- Avoid running or any type of fast motion in the cleanroom as fast movements generate high levels of contamination.
- Do not lean or sit on equipment or work surfaces.
- Do not work in the cleanroom when feeling sick (e.g., cold, flu, stomach illness).
- In the cleanroom, bend (90⁰) towards the floor when sneezing or coughing, or sneeze/cough in a cleanroom wipe. Do not sneeze/cough in gloves.
- Only use cleanroom approved wipes in the cleanroom area.
- Only bring cleanroom paper (e.g., cleanroom notebook) and plastic-laminated paper in the cleanroom. Follow wipe-down procedure when entering the cleanroom with such items.
- Do not use pencils, retractable pens, retractable ballpoint pens or erasers in the cleanroom. Use Sharpie’s or non-retractable ballpoint pens for writing in the cleanroom.
- Keep isopropyl alcohol (IPA) and methanol bottles located in the gowning room and cleanroom in their respective locations. Do not switch or remove them.
- Wipe down any item dropped on the cleanroom or gowning floor with 70% IPA.
- Do not pull on the black emergency handle to operate the automatic sliding doors. This will cause the doors to fall out of the frame.
