Mandatory Dress Code for CNF Clean Room

We have a strict dress code for every person entering our clean room.

To enter the CNF clean room, you must be wearing:

  1. Shoes and Socks

    Socks or stockings are required. Shoes must be closed-toe shoes that fully enclose the heel and the top of the foot. Additionally, the shoes must not have a high heel (over one inch) or a deep cleat that may hold mud or other dirt. Also, your shoes must be clean and dry when you enter the facility.

    Not Allowed: Sandals, open weave shoes, or shoes that expose the top of the foot.
  2. Shirt

    Your shirt must be at least a short sleeve shirt that is long enough to reach your pants (no bare midriffs) and it must not have a deep neckline.

    Not Allowed: Tank tops, halter tops, and spaghetti strap tops.
  3. Pants

    Pants must be full-length, from waist to ankle.

    Not Allowed: Shorts or cropped pants, tight pants such as "skinny jeans", yoga pants or leggings. NO skirts or dresses.
  4. Face Mask

    The CNF requires a face covering at all times inside lab spaces including gowning.

    Not Allowed: Cloth masks; N95 masks without EH&S pre-approval.

In addition: religious headwear is generally allowed if it will fit inside a clean room suit hood (but no baseball caps, etc.), and long hair should be tied back.

Finally, cameras are allowed -- but please ask your tour guide before you use a flash and remember to wipe down your camera.
