During the COVID-19 (CV-19) crisis, the term mask is frequently used to collectively describe a variety of distinct items, namely: Cloth Face Coverings, Disposable Masks, Medical-Grade Surgical Masks, and N95 Respirators. The following brief summary is provided as an aid in understanding the distinctions between the major categories of masks (face coverings) and their use in reducing the spread of and providing protection from the SARS-CoV-2 virus that causes CV-19.
For clarity, wearing a face covering is only one tool for reducing the spread of COVID-19, and doing so is not a substitute for physical distancing of at least 6 feet for social distancing or 9 feet during prolonged work in the same lab or research workspace with others.
Frequent hand washing is a must!

You should be using a Fire Resistant Mask instead.
Mask Type
Disposable Masks
Details
The mouth and nose are fully covered.
Fits snugly, but comfortably against the side of the face, secured with ties or ear loops.
Disposable masks may only be worn for one day and then must be disposed of in the trash.
Use
Required for Academic Division community (see UVA Policy) use in non-healthcare settings where 6-foot social distancing cannot be consistently maintained.
Not intended to provide protection from inhalation of small particles or virus aerosols.
Provides protection to others by reducing exposure to the saliva and respiratory secretions of the wearer.
Not considered Personal Protective Equipment (PPE) as defined by OSHA.
Do Not Use When
Your Disposable Mask has a built-in valve. Use a Disposable Mask without a built-in valve instead.

Mask Type
Medical-Grade Surgical Masks
Details
FDA-approved masks to protect the wearer from large droplets and splashes; helps contains wearer's respiratory emissions.
The mouth and nose are fully covered.
Fits snugly, but comfortably against the side of the face, secured with ties or ear loops.
Use
These masks are usually reserved for healthcare workers and other approved areas with task-specific hazards determined by EHS.
When faculty, staff, and students are required to wear Medical-Grade Surgical Masks for protection, they are considered Personal Protective Equipment and the use is subject to regulation by the Occupational Safety & Health Administration.
Do Not Use When
Your Medical-Grade Surgical Mask has a built-in valve. Use a Medical-Grade Surgical Mask without a built-in valve instead.
Performing procedures which create aerosolized particles. Use an N95 respirator instead.
Mask Type
N95 Respirators
(alternative name: N95 Air-Purifying Respirators)
Details
The mouth and nose are fully covered.
N95 respirators are approved by the National Institute for Occupational Safety and Health (NIOSH).
To be effective, N95s must provide a tight seal around the wearer’s face; therefore, fit-testing is required.
Under normal circumstances, discarded at end of use. Potential for decontamination, reprocessing and re-use. (e.g. UV-light, Hydrogen Peroxide Vapor, and others referenced by CDC).
Use
Designed to reduce inhalation of small, aerosolized particles, including virus aerosols.
CDC does not recommend that the general public purchase N95 respirators for protection against virus aerosols as N95s are in limited supply at this time and should be reserved for health care workers and other medical first responders.
When faculty, staff, and students are required to wear N95s for protection, they are considered Personal Protective Equipment and the use is subject to regulation by the Occupational Safety & Health Administration.
Do Not Use When
Your N95 respirator has a built-in valve. Use a N95 respirator without a built-in valve instead.

EPA List N Disinfectants for Use Against SARS-CoV-2
Custodial services is conducting cleaning of public areas in accordance with CDC recommendations. These areas include counters, tabletops, door handles, kitchen surfaces, bathroom fixtures, push plates, light switch panels, railing and similar frequently touched surfaces in public areas.
Surfaces in spaces such as research laboratories, offices, student living areas, and similar types of spaces, which are not typically cleaned by custodial services are excluded. Some areas of grounds, specific to the operation, clean to the standard of their department or unit’s operational needs.
Use disinfectants recommended by CDC against SARS-CoV-2 in accordance with manufacturer recommendations. See the EPA’s Registered Antimicrobial Products for Use Against Novel Coronavirus SARS-CoV-2, the Cause of COVID-19 as well as the American Chemistry Council’s (ACC) Center for Biocide Chemistries (CBC) for a list of products that have been pre-approved by the EPA for use against emerging enveloped viral pathogens.
CDC recommends disposable wipes so that commonly used surfaces (e.g. keyboards, desks, remote controls) can be wiped down by students, staff, and faculty before each use.
Be considerate of potential chemical incompatibilities and sensitivities of personnel when employing local disinfection techniques.
Contact EHS if you have any questions regarding appropriate disinfectants.
Departments and laboratories are responsible for acquisition of their own supplies. Because of the limited supply of hand sanitizer, it is recommended that you wash your hands at a sink with soap and warm water for at least 20 seconds, whenever possible.
Due to the unique hazards and specialized equipment in research spaces, laboratory personnel are responsible for cleaning and disinfection of laboratory areas. Alternatively, Service Master Restore of Charlottesville (434-293-3366 or 434-422-6401) is available to provide professional laboratory cleaning and disinfection services.
Departments should contact the vendor directly to coordinate services and provide a departmental issued purchase order.
EHS has published guidance for laboratories who wish to perform the disinfection themselves.
EHS delivery of alcohol based hand sanitizer and disposable masks has been discontinued.
Supplies can now be ordered through UVA Procurement.
See their COVID-19 Supplies Guide for more information.
Check with your supervisor about any other PPE-related needs.
Research as of 19 March 2020 suggests that SARS-CoV-2 can survive up to 72 hours on surfaces, but in most instances, the risk of infection resulting from contact with a contaminated surface is unlikely after a few days. Please refer to this report from Johns Hopkins for more details:
https://hub.jhu.edu/2020/03/20/sars-cov-2-survive-on-surfaces/
Per CDC Biosafety guidance, it is highly recommended to perform any procedures with human samples from suspected or confirmed COVID-19 patients in a Biosafety Cabinet(BSC). If a BSC is not available, additional precautions to provide a barrier and reduce risk to personnel should be implemented, such as additional PPE, splash shields, and centrifuge safety cups. Any activities related to SARS-CoV-2 virus isolation or propagative procedures must be performed in BSL3 containment. These activities would require IAR modifications and appropriate IRB approval for patient sample collections.
If you are considering research involving specimens from CoVID-19 patients or with SARS-CoV-2 virus please contact the Institutional Biosafety Committee Coordinator, Paul Skoglund at ps5d@virginia.edu, who will provide guidance on how to proceed with this type of research.
