Building Services custodians, on a daily basis, clean and disinfect classrooms, lobbies, atriums and high-contact public surfaces such as light switches, handrails, elevator buttons and doorknobs.
Building Services custodians clean all bathrooms across campus at least once per day.
Building Services custodians clean and disinfect restrooms and high-contact surfaces in public spaces. Individuals should clean and disinfect frequently touched items in their own work area on a daily basis, including computer and peripherals, doorknobs and handles, light switches, phones, desks, tools and other shared equipment.
In the case of shared departmental spaces such as break rooms, users must take responsibility for wiping down surfaces and equipment, including tabletops, refrigerator and microwave door handles, coffee makers, and photo copier touch panels.
If you need disinfectant wipes or other cleaning supplies for your work area, request a supply from your supervisor. Supervisors may contact email@example.com if assistance is needed to obtain supplies.
A number of chemical products are anticipated to be effective at inactivating the COVID-19 virus, based upon previous testing of the disinfectant against similar viruses. The Environmental Protection Agency (EPA) maintains the criteria used to assess the effectiveness of disinfectants and maintains a list of products and conditions of use (such as contact time) that are anticipated to be effective against the COVID-19 virus. These products are found under the EPA List N: https://www.epa.gov/pesticide-registration/list-n-disinfectants-use-against-sars-cov-2-covid-19
Due to interest in this subject, the EPA has recently launched an interactive version of List N to make it easier to search. https://cfpub.epa.gov/giwiz/disinfectants/index.cfm
A number of manufacturers are actively testing their products the verify their product’s effectiveness by directly testing against the COVID-19 virus. More information will be provided once additional information is available on disinfectants verified against COVID-19.
Unless clearly indicated in the instructions provided by the manufacturer, most cleaning products (including disinfecting wipes) designed for use on hard surfaces should not be used to sanitize your hands. These products are often formulated with harsher chemicals than similar sanitizing wipe products intended for use on a person and may result in harm, such skin injury or irritation and serious injury to the eye if remaining residue is accidentally wiped into the eyes.
- What has the University done to improve building ventilation systems in light of the risk of exposure to COVID-19?
- I'd like to have the ventilation in my building/office assessed. What should I do?
- What can I do to improve ventilation in my building?
- How much outside air is provided to our campus buildings?
- Is air in my office recirculated from other parts of the building?
- Some of the air in my building is recirculated. If a co-worker is diagnosed with COVID-19, will I need to quarantine due to the recirculated air?
- I work in a small office and I am concerned because there is no mechanical ventilation system.
- Should I purchase or bring in an air purifier for extra protection?
- What about filtration units in classrooms?
The University has taken a number of steps, including:.
- Servicing HVAC systems in buildings that have not been occupied to ensure that they are working properly and efficiently.
- As possible, increasing the amount of outside air and decreasing the amount of recirculating air in buildings.
- Where possible, replacing air filters with highly efficient filters, such as MERV-13 filters.
- Reducing or disabling occupancy controls that decrease ventilation rates when the space is unoccupied.
At this time, Facilities and EHS are not conducting additional ventilation assessments in campus buildings.
- If your space has operable windows and opening them will not disrupt air conditioning or heating, open windows while occupying the space. Do not leave windows open and unlocked when the building is unoccupied.
- Leave on exhaust fans in restrooms if they are operated by a switch.
*Wherever possible, the University meets or exceeds the outside air parameters recommended by ANSI/ASHRAE Standard 62.1-2019 on Indoor Air Quality.
Ventilation systems in our older buildings may not provide the amount of outside air specified by this standard. However, all of our air handler units have been set to provide the maximum amount of outside air while maintaining reasonably comfortable temperature and relative humidity levels.
With the exception of laboratories and machine shops, the ventilation system in most buildings on campus provide a mix of outdoor and recirculated air. Even the most stringent indoor air quality standards for classrooms, offices and assembly areas allow for a mix of outside and recirculated air.
Recirculated air is filtered before it is delivered back to occupied spaces. The quality of a filter is based upon its ability to capture small particles. The MERV (Minimum Efficiency Reporting Values) rating is a measurement of a filter's ability to capture particles of a certain size and range from 1 to 16. The higher the MERV rating the better the filter is at trapping certain size particles. When possible, our ventilation systems are equipped with MERV-13 filters, as recommended by CDC. All air filters are periodically cleaned and replaced by trained Facilities staff to ensure proper function
No. Decisions about the need to quarantine a staff member or student are made by UHS physicians and nurses and are based primarily upon your physical distance from the ill person. You may be told to quarantine only if you were within six feet of the ill person for more than 15 minutes over the course of 24 hours during a specific window.
I work in a small office and I am concerned because there is no mechanical ventilation system.
Some older buildings are equipped with heating and cooling devices but do not receive fresh air via a mechanical ventilation system. If windows are available, open them unless opening the windows affects your seasonal allergies. If the unventilated space is used for assemblies of staff or students, EHS may make recommendations on how to safely use the space.
Additional air purification is not necessary and can place undue demand on building electrical systems. If a department wishes to purchase portable air purifiers, please see the portable HEPA filter guidance found on the EHS website.
For those few classrooms with no mechanical ventilation, portable filters have been placed by Facilities (if assigned by the Registrar) or may be purchased by departments (if managed at the department level). These units must comply with guidance outlined on the EHS website.
