Cleaning and Disinfecting

On this page:

Faculty and staff should be mindful of potential risks in a workplace and take appropriate action to protect your personal health. UB Environment, Health & Safety can provide guidance to protect UB workers from adverse health effects due to these, and other, environmental causes.

COVID-19 Related Cleaning Practices

In general, UB has returned to pre-COVID daily cleaning and disinfecting practices. The CDC advises that unless a space has been exposed by a COVID-positive individual, cleaning once a day is usually enough to sufficiently remove virus that may be on surfaces and help maintain a healthy facility. In the event that an individual is confirmed to have COVID-19 or other virus warranting special attention, UB will follow CDC guidelines in cleaning and disinfecting the exposed areas. 

These cleaning practices include:

  • If more than 3 days have passed since the person who is sick or diagnosed with COVID-19 has been in the space, no additional cleaning (beyond regular cleaning practices) is needed.
    • If less than 24 hours have passed since the person who is sick or diagnosed with COVID-19 has been in the space, clean and disinfect the space.
    • If more than 24 hours have passed, cleaning is enough. Disinfecting may also be done depending on certain conditions.
  • Close off areas used by the person who is sick until after cleaning and disinfecting.
  • Wait at least several hours before cleaning and disinfecting
  • Focus on the immediate areas occupied by the person who is sick or diagnosed with COVID-19 unless they have already been cleaned and disinfected.
  • During cleaning, opening doors and windows; increase air circulation in the area if possible
    • Do NOT deactivate central HVAC systems. These systems provide better filtration capabilities and introduce outdoor air into the areas that they serve.
  • Use the appropriate cleaning products.
  • Wear mask and gloves.
  • Vacuum the space if needed.
How to Disinfect Surfaces

We all need to do our part and wipe down personal work spaces, private offices and commonly touched areas to stop the spread of illness.

  1. Wipe surface with an antibacterial wipe or alcohol-based spray. 
  2. Allow surfaces to remain wet for three to four minutes before allowing them to air dry or wiping away.
  3. Discard wipe or paper towel immediately after use; wash hands.

Cleaning Products and Supplies

UB University Facilities’ custodial team uses a broad range of disinfecting products, all of which are EPA- and CDC-certified for eradicating COVID-19 and other contagions. All disinfectant products are used according to the manufacturers’ recommendations.

  • Centrally scheduled classrooms are equipped with wall-mounted sanitizing wipe dispenser to enable faculty, staff and students to wipe down commonly used surfaces (e.g., keyboards, remote controls, desks). These Benzalkonium Chloride sanitizing wipes are FDA and EPA approved for use on hands and for destroying the coronavirus. 
  • Individual departments are responsible for procuring cleaning supplies for their areas.

Cleaning Buses and Shuttles

  • UB Parking & Transportation Services disinfects Stampede buses and UB shuttles twice daily.
  • High-touch surfaces such as handrails and seat backs are wiped down periodically throughout the day.
  • Transit team members have been trained to use disinfecting fog to thoroughly sanitize campus shuttles.
  • Zipcar cleans its car-sharing automobiles with antiviral and antimicrobial solutions and has deployed periodic sanitizing procedures. 

Cleaning of Clinical, Research and Laboratory Spaces

  • Clinical or counseling areas that are open to the public are cleaned overnight.
    • Additional cleaning throughout the day will need to be supplemented by departmental staff as needed.
    • Departmental leaders for clinical spaces are encouraged to work with Environmental Health & Safety (EH&S) regarding the procurement and proper use of personal protective equipment (PPE).
  • Research and lab spaces are cleared of trash and floors are cleaned daily during the work week.
    • Because lab spaces are considered controlled environments, UB Custodial teams have limited access to these spaces.
    • More extensive general cleaning and sanitizing will continue to be the responsibility of laboratory personnel.
    • For more information, visit the Research & Economic Development COVID-19 page.
  • University Facilities does not clean lab equipment. Lab equipment should be sanitized according to manufacturers’ recommendations.
