Figure 1Levels of regulation within an SRL to promote a safe SRL workplace. A brief overview of the levels of regulation needed during the global SARS‐CoV‐2 pandemic in order to minimize risks associated with operating a SRL. [Color figure can be viewed at wileyonlinelibrary.com]
Figure 2Representative examples of enacting physical distancing guidelines within an SRL. (A) Diagram from Newcastle University, Newcastle upon Tyne, UK. On the floors, tape markings have been created to show entry points to access instruments. Perspex screens have been erected between instruments. Importantly all users face away from both other users and away from the central access to the lab. (B) Diagram from National Laboratory of Flow Cytometry, Department of Immunology, Biomedical Research Institute, National Autonomous University of Mexico. Notice tape marking between instruments, users face toward walls, and signage on lab entrances. [Color figure can be viewed at wileyonlinelibrary.com]

Risk assessment for operating a SRL during the COVID‐19 pandemic
| Risk | Risk Level | Breach/issue | Mitigation measures |
|---|---|---|---|
| Continuous flow of people in the SRL | High |
Physical distancing Room capacity |
‐Staggered schedules for SRL staff ‐Use of equipment with defined intervals and time between users. ‐Floor tape and Perspex screens to restrict area access ‐Constant disinfection of high traffic surfaces. ‐Use of appropriate PPE |
| Confirmed COVID‐19 case within the SRL/Building | High | Confirmed virus exposure to users and areas |
‐Prepare SOP for such an event ‐Include a business continuity plan ‐Instigate contact tracing using instrument booking records |
| Ventilation system with air recirculation | High | Recycled air not clearing potential viral particles |
‐Turn off ventilation system, open windows ‐Use of appropriate PPE |
| User training | High |
Physical distancing Room capacity |
‐Remote training using programs such as “team viewer” ‐If not possible; Use of appropriate PPE ‐Laser pointers to allow physical distancing ‐Use of training videos and other educational material |
| Sorting | High |
Physical distancing Room capacity |
‐Remote sorting using programs such as “team viewer” for sample/gating checks ‐Use of appropriate PPE ‐Sample drop off and pick up locations outside the sorting area/room |
| Sorting untested primary human sample | High |
Possibly infectious Aerosol generation during blockages, spills and handling |
‐ Sorting to be carried out in BCL3/PC3 level area ‐ Aerosol management system attached to sorter ‐ Alternative, use a sorter that does not generate aerosols. |
| Biometric lock to enter the SRL | Medium | High traffic/risk surface for transmission | ‐Provide sanitation station for frequent disinfection of the lock and hand disinfection before and after contact |
| Entrance and exit at the same door. | Medium |
Physical distancing restrictions High traffic/risk surface for transmission |
‐Staggered schedules/bookings ‐Keep the door open during normal hours to minimize transfer risk |
| Inadequate instrument spacing | Medium |
Physical distancing restriction Room capacity restrictions |
‐Space out instruments within the room ‐Move instruments to different rooms if not possible, stagger availability of instruments to comply with room capacity and/or physical distancing restrictions |
| Reception of suppliers and signing of printed documents. | Medium |
Physical distancing restrictions High traffic/risk surface transmission |
‐Schedule defined hours for reception of suppliers. ‐Use of appropriate PPE ‐Move to digital if possible, if not practice good hand hygiene |
| Staff and users unaware of new rules | Medium | Staff or users failing to follow the rules and putting others at risk |
‐Send out new SOP's to all users and institute OH&S teams ‐Ensure received and read through declaration document ‐Add signage to all rooms (physical distancing, room capacity limits, etc) |
| Analyzing untested unfixed primary human samples | Medium |
Increased risk of transmission Resuspension method generating aerosols Spills |
‐Impose all untested/unfixed primary human samples be fixed with an approved method before acquisition on instruments. ‐ If not possible due to functional or time course experiments move an instrument into a BCL2/PC2 hood. |
