CALS COVID-19 cleaning and disinfecting guidance communication

Should an employee in CALS test positive for COVID-19, University Health Services (UHS) will contact the CALS Divisional Disability Representatives (DDR) who will then notify the supervisor and the dean. The supervisor should then develop a plan based on the Smart Restart cleaning and disinfecting guidance to clean and disinfect any areas where the employee was working when they tested positive. UHS and EHS can assist by evaluating the situation and providing guidance based on the information provided.

While UHS and EHS will help to coordinate cleaning and disinfection efforts, the unit in which the positive case occurred may be responsible for the actual cleaning and disinfecting of the area. This is a change from previously when EHS would conduct cleaning, but they are no longer able to do this given demands elsewhere on campus. 

When units are expected to clean a work area, they should follow the Simplifying Campus Cleaning Responses Related to COVID-19 and Incident Cleaning in Areas where a Known or Potentially Contagious Employee was Present guidance documents developed by EHS. The guidance documents provide information on when to enter the space, the cleaning and disinfecting process, and what personal protective equipment (PPE) to use. PPE used for cleaning and disinfecting can be ordered through the CALS-specific PPE procurement and distribution process (follow instructions for “Lab and Office PPE”).

If there are any questions about cleaning practices related to COVID-19 or infection control in the workplace, you can reach EHS by email at

To further assist with cleaning and disinfecting, EHS created cleaning and disinfecting guidance documents for a number of scenarios. The documents are located at the FP&M Returning to Campus Safely webpage and linked below.
