Enhanced Cleaning and Disinfecting Procedures

Purpose: 

The University of Portland is taking measures to prevent the community spread of COVID-19 which includes undertaking enhanced cleaning and disinfecting procedures across campus. By performing the duties of basic cleaning and surface disinfection in a specific way, we can help to create safer environments.

Cleaning and Disinfection of Surfaces:

i. Surfaces will be cleaned daily and may be cleaned additional times daily if they appear visibly dirty. If surfaces are dirty to sight or touch they will be cleaned using a detergent or soap and water prior to disinfection.

ii. Clean surfaces and objects with H2Orange Cleaner. Clean from high to low, moving from clean to dirty so that cross-contamination does not occur during the cleaning process.

iii. Use an EPA registered disinfectant (HALT – EPA Reg. 10324-93) for use against the novel coronavirus. Follow the manufacturer’s instructions for safe and effective use of all cleaning and disinfection products (dilution of concentration, application method, contact time, required ventilation, use of PPE, etc.).

iv. For the cleaning of electronics such as keyboards, mice, etc. use an alcohol based cleaner, wipe, or spray of at least 70% alcohol as the disinfectant. Wipe down electronics with a saturated but not dripping paper towel or wipe. If necessary dry surfaces thoroughly to prevent pooling of liquids. Do not use aerosolized air to blow dust off of electronics.

Enhanced Cleaning of Frequently Touched Surfaces:

In addition to routine cleaning and disinfection, the Physical Plant staff have increased the frequency of cleaning and disinfecting of frequently touched surfaces. Increased frequency of cleaning and disinfecting removes bacteria and viruses, including the novel coronavirus, which reduces the chance for surface transmission. Physical Plant has also extended their cleaning schedules to provide this service into the evenings and weekends.

Frequently touched surfaces include:

  • Door handles
  • Door knobs
  • Elevator buttons
  • Handrails
  • Tables and desks
  • Faucets
  • Light switches
  • Public telephones
  • Hallway ledges
  • Entrance gates
  • Seating
  • Counters
  • Other restroom fixtures
  • Sneeze guards
  • Classroom Instructor Podiums

Surfaces that are not regularly touched should be cleaned but do not require additional disinfection. Disinfectants should not be used or applied to items that are regularly touched by children.

Outdoor areas with shared seating and community surface areas should be cleaned and disinfected regularly. The targeted use of disinfectants on outdoor hard surfaces and objects frequently touched should follow the same protocols as cleaning and disinfection of indoor surfaces.

Safety Guidelines during Cleaning and Disinfection:

i. Wear disposable gloves when cleaning and disinfecting. Gloves should be discarded when cleaning and disinfecting is completed. Wash hands for a minimum of 20 seconds immediately after gloves are removed, following the CDC’s guidance. Never reuse disposable gloves.

ii. Follow the recommended PPE for the cleaning or disinfecting products used; consult the Safety Data Sheet and wear appropriate protection.

iii. Store chemicals in labeled, closed containers. Keep chemicals in a secure area. Store them in a manner that prevents tipping or spilling. All chemical containers should be labelled according to Globally Harmonized System standards.

iv. Maintain cleaning tools and textiles in a sanitary and clean manner and assure they are in good working order. Textiles such as cleaning cloths and floor mops should be laundered on a regular basis.

v. If surfaces are visibly dirty they should be cleaned prior to disinfection.

Definitions:

Cleaning: Cleaning refers to the removal of germs, dirt, and impurities from surfaces. Cleaning does not kill germs, but by removing them, reduces their numbers and the risk of spreading infection. Cleaning is typically performed using soap, detergents, or other cleansers, and clean water, before using a disinfecting method.

Disinfecting: Disinfecting refers to using chemicals to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it further reduces the risk of spreading infection. Disinfecting is typically performed using approved commercial or household disinfection solutions for their appropriate contact time. Disinfectants are the only products approved by the EPA to kill viruses on hard surfaces, and are effective against bacteria and viruses.

Sanitizing: sanitizing contains chemicals that reduce, but do not necessarily eliminate, microorganisms such as viruses from surfaces. Sanitizers are often developed to target specific bacteria and are not known to be effective against viruses.
