Protect Purdue Guidance for the use of Face Shields

University protocols to prevent the spread of COVID-19 have evolved since early 2020.  Safe face shield usage was reviewed at the July 6, 2020 meeting of the Medical Advisory Team. The agreed upon uses of face shields are described below. This guidance does not change the use of face shields under existing non COVID-19 hazard assessments and protocols.

This guidance does not replace the requirement for facemasks in public areas and common spaces.

 Approved uses for face shields:

  1. Researchers and instructors, teaching assistants, staff, and students (in instructional labs) may choose to wear face masks and face shields when close proximity work is required for extended periods of time.  Example: two researchers working side-by-side at the same lab equipment station for 30 minutes.
  2. Face shields may be worn for additional protection over a face mask.

 Guidance details:

  1. Face shield design:
    1. Face shields should cover the eyes, nose and mouth, and be substantial enough to remain in place without excessive readjustment.
    2. If the face shield appears damaged or torn – discard and obtain a replacement
  2. Cleaning procedures for reuse:
    1. Follow the manufacturer’s recommended instructions for cleaning and disinfection.
    2. When manufacturer instructions for cleaning and disinfection are not available, face shields may be cleaned as follows while wearing gloves:
      1. Carefully wipe the inside, followed by the outside of the face shield using a clean cloth saturated with neutral detergent solution or a cleaner wipe.
      2. Carefully wipe the inside, followed by the outside of the face shield using a wipe or clean cloth saturated with EPA-List N registered disinfectant solution. Allow for appropriate disinfectant dwell time
      3. If shield is streaked or has a cloudy film, clean mask with a soft, water dampened cloth or use an alcohol pad.
      4. Fully dry (air dry or use clean absorbent towels).
      5. Remove gloves and perform hand hygiene.
  3. Obtaining face shields:
    1. Face shields may be obtained from Procurement.
