Personal Hygiene

Practicing personal hygiene and wearing face coverings in combination with maintaining proper physical distance from others is critical to preventing the spread of the virus on campus. Community responsibility includes reminding peers and colleagues to practice personal hygiene and wear personal protective equipment.

Hygiene Measures

  • Wash your hands often with soap and water for at least 20 seconds especially after you have been in a public place, or after blowing your nose, coughing, or sneezing.
  • If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.
  • Cough or sneeze into a tissue and dispose of used tissues immediately into a trash can. If you don't have a tissue, cough or sneeze into the crook of your elbow, not your hands.
  • Avoid touching your eyes, nose and mouth.
  • Do not shake hands and avoid physical contact with others.
  • Eat away from others. Wipe down the eating space before and after the meal.
  • Supervisors should encourage breaks for employees to wash hands or use hand sanitizer.
  • Post signage to encourage good hygiene (see below).

Personal protective equipment (PPE) is an important component of virus containment. Below are current PPE requirements.

Face Coverings

All University employees, students and visitors are required to wear a face covering at all times while on campus (inside buildings and outside) to help prevent the spread of disease, except as provided below. Acceptable face coverings include those provided by DU, where available, or an individual’s face covering of choice, so long as it meets the applicable CDC and CO State recommendations. Individuals should maintain six-feet separation even when they are wearing face coverings. Face coverings should:

  • Cover the nose and mouth at all times
  • Fit snugly but comfortably against the face
  • Include multiple layers of fabric
  • Allow for breathing without restriction
  • Be disposable or be washable and machine dryable without being damaged or changing shape
  • Be looped around the ears or tied behind the head and neck
  • Remain in place until taken off safely
  • Be replaced with one that does not need to be frequently adjusted if the initial face covering moves during work
  • Be replaced when they become dirty, wet and/or difficult to breathe through
  • Fleece neck gaiters are currently not recommended
  • Face coverings are required of everyone on campus; even if you have already tested positive for COVID-19 or if you have been vaccinated you are required to wear a face covering on campus at all times.


  • Individuals alone in single offices or in dorm rooms (with the door closed) are not required to wear face coverings. 
  • Individuals may take off their face coverings to eat and drink as long as they remain 6 feet away from others; however, eating and drinking inside classes is not permitted.
  • An individual is not required to wear a face covering if it would inhibit the individual’s health, provided that employees who cannot wear face coverings for this reason provide DU with documentation. In these instances, DU will make every effort to assign such employees to duties that do not put them in close proximity with other employees or the public.

Other Protective Equipment

DU will provide gloves and other protective equipment as appropriate for an individual employee’s job duties. It is the department’s responsibility to provide gloves and PPE for task-specific jobs as required by OSHA, CDC or DDPHE.

N95 masks are to be worn by University staff in response to a positive case. The required use of the N95 mask requires a fit test through Environmental Health & Safety (EHS) and medical clearance to wear surgical masks is also provided for many on-campus roles, including custodial and dining, as these face coverings provide additional protection above cloth face coverings, are disposable and are comfortable without restricting airflow even during more strenuous work.

Cleaning, Disinfection, HVAC & Ventilation

The Facilities Management and Planning (FMP) Division has been diligently operating since the onset of the COVID-19 pandemic, successfully establishing and implementing cleaning, disinfection and building operational protocols to prevent the spread of the virus. Improvements have been made throughout the year as our staff have learned the best procedures and equipment to use. We have expanded the frequency of cleaning and disinfection by custodial staff, with increased attention to high touch points and common areas, and with the support of additional equipment (e.g. UV, electrostatic) as warranted. We have established protocols for cleaning and disinfection and provided guidance and supplies for individuals regarding the cleaning and disinfection of personal space (e.g. individual offices, dorm rooms). We have also assessed the building HVAC systems and increased ventilation across campus. Classrooms are cleaned and disinfected daily. Between classes, disinfecting supplies, including wipes and hand sanitizer, are provided in the classroom, allowing individuals to wipe their areas prior to the start of the class.

Cleaning: While cleaning refers to the removal of dirt, germs and impurities from surfaces, it alone does not kill germs. Cleaning levels will be adjusted throughout campus in order focus custodial resources on the disinfection protocols necessary for a successful virus mitigation. The updated levels of service and frequencies of cleaning and disinfection are available here.

Disinfection: Disinfection works by using chemicals to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs. But killing germs that remain on a surface after cleaning further reduces any risk of spreading infection. Three levels of disinfection have been established based on the response required to mitigate the virus:

  1. LEVEL 1: Precautionary Disinfection - Routine custodial assignments are followed in addition to focused/prioritized disinfecting with standard cleaning disinfectant on high contact areas/touch points (i.e. elevator controls, doorknobs, push plates, handrails, handles, telephone receivers, etc.).
  2. LEVEL 2:  Enhanced Disinfection - This involves using a disinfectant (Virex) with a higher efficacy on high contact areas to include reachable air vents. Includes a one-time application of an anti-microbial to the carpeted areas.  Increased disinfection frequency of high contact points (i.e. elevator controls, doorknobs, push plates, handrails, door handles, telephone receivers, water dispensers, low air vents, etc.).  Increase to twice a day cleaning/disinfection of lavatories.
  3. LEVEL 3: Decontamination of a Positive Contact Area - This procedure involves an electrostatic application of disinfectant in an area or space when a confirmed positive SARS-CoV-2 individual has had contact in a building. This procedure will be applied where the positive contact occurred in addition to the traced path of the individual. Areas to be disinfected will be determined on a case-by-case basis. The area will be closed 24 hours prior to this procedure to allow for aerosols to settle. Occupancy will be allowed one hour after the completion of this procedure.

Supplies: Improvements were made to provide supplies to all buildings over the Fall quarter and in preparation for Winter. In fact, 3694 canisters of wipes were distributed in Fall term. Facilities has established a service to resupply the disinfection stations in classrooms and common areas with hand sanitizer and disinfecting wipes three times a week while maintaining a central supply of wipes in each building for use in offices and lab spaces. In any situation, building coordinators and COVID-19 Access Managers can still submit a Disinfectant Material Request for their buildings. To receive disinfectant product for your office area, please work with your building manger/COVID-19 coordinator to submit an online Facilities Work Request and supplies, will be delivered to the room referenced in the request. Facilities centrally purchases disposable wipes, hand sanitizer, cleaning supplies and COVID-19 building signage. Mail Services delivers cleaning supplies between 7:30 a.m. and 3:30 p.m. on Monday, Wednesday and Friday.

HVAC & Ventilation: Facilities Management and Planning is following guidance from the EPA, CDPHE and ASHRAE to assist with decision-making on how to operate HVAC systems and how to determine appropriate modifications. Each building has been evaluated with respect to ventilation in coordination with other preventative measures appropriate for the space. FMP has increased the ventilation rates and the use of outdoor air as systems will allow for proper operations. MERV 13 filters are currently being used in the buildings on campus that have been designed to use them. 41 in-room HEPA filtration units have been installed. Another 18 units using photocatalytic oxidation and ultraviolet light have been installed at Ricks Center and are on order for Fisher Early Learning Center. 8 negative pressure HEPA units have been installed in the HCC. The following 42 buildings have MERV 13 filters installed and in use during the fall quarter:

  1. Ricketson Law

Buildings with 100% outside air (single pass) therefore no filter upgrade needed:

  • Seely Mudd

Additionally, aerosol modeling has been conducted to set occupancy limits for specialty classrooms that support the Lamont School of Music and the Theater Department. The goal of this modeling was to establish the class duration, break length and number of vocalists, performers or wind instruments within the classroom such that the risk to occupants was no different than a person attending an in-person lecture class on campus. Carbon dioxide monitors have been added to several rooms in Lamont to ensure room air modeling of aerosol deposition are accurate.

Dedensification, Social Distancing & Support

All University personnel, students, and visitors are expected to maintain social distancing at all times while on campus to help prevent the spread of disease. Dedensification will reduce the maximum occupancy of spaces in compliance with local and state requirements based on the phase of reopening. The maximum occupancy of rooms will be indicated and posted at the entrance of classrooms, meeting rooms, labs, restrooms, etc.

Social distancing measures should include the following

  • Maintain six-foot distancing from other individuals whenever possible
  • Workstations should be at least six feet apart
  • If workspaces are less than six feet apart, spread out throughout the building using unoccupied spaces such as conference rooms or classrooms.
  • Classrooms should be arranged with six-foot distancing and updated occupancy for scheduling. 
  • Furniture should be re-arranged when possible, and in the cases where it cannot, signage is to be placed indicating that the item is out of service

Restroom occupancy has been reduced by placing every other fixture out of service, including stalls, urinals and sinks. Updated occupancy will be indicated at the door. In many cases, only one person will be permitted at a time.

In-person Meetings Include online conferencing, email or phone options to reduce the frequency and density of in-person meetings. In-person meetings should be short in length and in a room where participants can keep a distance of six feet apart and under 50% occupancy.

Limit gathering in shared spaces such as break rooms, copy rooms or other places where people socialize. Remain six feet apart.

Flexible Work Arrangements:

  • Supervisors should stagger shifts and breaks to reduce the number of employees in shared spaces.
  • DU employees are encouraged to consult with their supervisor regarding telecommuting where appropriate
  • Supervisors and COVID-19 Access Managers should consider using staggered work hours to reduce the number of employees present at the same time.
  • Employees can request work accommodations (

Travel Restrictions

Transmission of the virus in the early months of the pandemic was correlated strongly to individuals who traveled to regions with widespread or emerging outbreaks of COVID-19. As the pandemic matured, travel remained one of the correlating factors with new case data tied to airports and along interstate highways. The University has maintained a travel restriction policy throughout the response. These policies are intended to reduce or minimize the risk for transmission during asymptomatic phases as well as to protect faculty, students and staff from situations that present risk as a function of job responsibility. These policies are essential to the University maintaining control of the virus within our community especially because more than 70% of our students come from out of state or out of country. Our best chance to remain face to face and not have an outbreak on campus is to control the number of potential asymptomatic individuals in our community and to reduce the number of days those individuals could be spreading the virus without knowledge.

To mitigate risk to our employees and minimize spread of the virus during Phase I and II of the campus access and support plan, travel is prohibited for non-essential domestic and international university travel. Academic deans and division heads are responsible for determining what travel for research in their division met criteria for essential. Persons returning from personal or business travel for out of state or international are required to self-isolate for 7 days per CDC guidelines at that time. 

Travel may be deemed “essential and not possible to postpone” if  THREE of the conditions on the list below are likely to occur should the travel be cancelled or significantly delayed:

  • Loss of grant funding, or failure to meet required completion deadlines 
  • Failure to meet contract deliverable requirements 
  • Significant damage to relationship with institutional partner 
  • Significant delay in academic progress, degree completion, or graduation  

Currently, conditions are such that any travel outside of Colorado requires a 7-day quarantine upon return before returning to campus.

In Phase III and IV of the campus access and support plan, travel may be discouraged for non-essential domestic and international university travel. Individuals returning from travel for business or personal reasons from a state that does not have widespread and elevated sustained outbreaks of the virus may return to campus immediately after travel while monitoring symptoms. The University uses the State and CDC criteria for high incidence rate and elevated incidence growth as the threshold definition. When the seven-day moving average daily incidence rates per 100,000 residents exceeds 10, the region will be considered to have high incidence with elevated incident growth. Individuals returning from travel from a state that exceeds that threshold or from international travel will be asked to self-quarantine for 10 days. The 10-day isolation is mandatory for individuals who have tested positive for COVID-19 and are asymptomatic. The University has decided to apply these quarantine guidelines to our travel restrictions. A list of the states exceeding the threshold will be published each Friday on the University COVID-19 response website. A list of the states exceeding the threshold will be published each Friday on the University COVID-19 response website. At this time, nearly every state is above the threshold; therefore all travel outside of Colorado requires quarantine.

Below is the chart explaining the thresholds for decisions around travel resumption, course travel and study abroad. This tool provides guidance on decision making for senior leadership.
