Cleaning/Disinfecting

Yale Facilities and EHS have established cleaning procedures and plans for campus workplaces. These procedures specify EPA/CDC-approved cleaners and methods. Plans identify the extent and frequency of workplace cleaning and decontamination. Custodians especially focus on cleaning and disinfecting high-touch surfaces (i.e., doorknobs, tables, light switches, handles, elevator call button, chairs, etc.), including offices, common area, and bathrooms. Work with your Facilities Superintendent and Custodial Team Leader to review your cleaning plans to ensure that areas of frequent or heavy occupancy receive additional cleaning.

While Yale custodians conduct more frequent and thorough cleaning, all members of the Yale community need to help keep workplaces clean. Managers should make cleaning supplies (e.g., disinfecting wipes and sprays) readily available at multiple locations, such as bathrooms. Follow EHS guidelines to routinely clean and disinfect workstations and other frequently touched surfaces. Wipe down commonly used surfaces, such as light switches, desks, tabletops, doorknobs, elevator buttons, touch screens, equipment, faucet handles, and handrails. If shared, desks, workstations, and offices should be cleaned and disinfected after use. Disposable wipes are convenient, but other cleaners described in EHS’ guidelines are effective too.

As described below, special procedures have been developed for cleaning workplaces where exposure to an individual with suspected and/or confirmed COVID-19.

Additional Cleaning/Disinfecting Guidance

  • Clean and disinfect areas as required in laboratories and in common/public spaces.
  • Clean high-touch surfaces daily in common areas (e.g. tables, hard-backed chairs, doorknobs, light switches, phones, tablets, touch screens, remote controls, keyboards, handles, desks, sinks).
  • Use disinfectants appropriate for SARS-CoV-2 (EPA Disinfectant List). Note: Lab disinfectants are easily made using 70% alcohol or a dilute beach solution. The CDC recommends five tablespoons of bleach per gallon or four teaspoons of bleach per quart.
  • See CDC recommendations for cleaning and disinfecting your work area (CDC Recommendations).
