COVID-19 Information

Staying healthy during the pandemic is a priority for all of us.  SLAC has developed safety protocols and requirements that adhere to the requirements by Stanford University, the Department of Energy, and the CDC, while allowing SLAC personnel, staff, researchers, subcontractors, and business visitors the best ability to continue doing science and working safety.   

Information for Internal Personnel

SLAC personnel with a log-in should visit our internal COVID-19 Resource Center  , where we keep a detailed website of COVID-19 resources, policies, and FAQs.  

Current COVID-19 Requirements at SLAC

  • Do not come on site to SLAC if you test positive for COVID or are experiencing COVID-related symptoms.
    If you have prior access to Health Check and you test positive or have symptoms, or have been in close contact with somebody who is positive, update Health Check and follow the guidance given.
    If you are a User, Visitor (business or casual), or Affliate, contact your Point of Contact (POC) if you test positive for COVID. 
  • Masking is not required, but strongly recommended (while the San Mateo County COVID-19 Community Level is green/low). You are encouraged to continue wearing a mask indoors or outdoors if you prefer to do so, especially when meeting in large groups.  
  • Masking is still required on Marguerite shuttles, in the Occupational Health Center office suite (in Building 28), in government vehicles with more than one occupant, and post-travel for 5 days. Where or when masking is required, N95s, KN95s, or surgical masks must be used. Cloth masks alone are not permitted but can be worn with a surgical mask underneath.

These requirements are in accordance with the Department of Energy's COVID-19 Workplace Safety and Reentry Framework and will be in place while San Mateo County's COVID-19 Community Level remains in orange (high).  These requirements apply to everyone entering the SLAC site, including staff, users, contractors, and visitors. 

Access Details

SLAC Employees, Stanford Staff, and SU Graduate Students

SLAC employees need to complete ESH Training Course 100-R  , Stanford staff and students should do their appropriate SU required training.  Do not come on site to SLAC if you test positive for COVID or are experiencing COVID-related symptoms; update Health Check and follow the actions provided.  SLAC personnel with a log-in should visit our internal COVID-19 Resource Center   for additional information.  

Subcontractors

Subcontractors are required to follow all SLAC COVID-19 safety protocols while on-site, including face coverings when the community level is medium or high.  Please discuss requirements with your SLAC Procurement Point of Contact.  Requirements to come on-site with SLAC Field Construction Manager (FCM) concurrence may include badge-specific requirements (check with your FCM/Point of Contact).  See the SLAC Subcontractor Badging Process   for more details about badging.

Visitors (Business Visitors and Casual Visitors)

To request visitor access, the host should request their visitor complete the access form at the SLAC Access Portal.  The portal is used to capture all access to SLAC.  

Do not come on site to SLAC if you test positive for COVID or are experiencing COVID-related symptoms; contact your Point of Contact if you test positive for COVID. 

Visitors are required to follow all SLAC COVID-19 safety protocols while on-site, including face coverings when the community level is medium or high. Please discuss current protocols with your Point of Contact.

Scientific Users

Each User Facility (SSRL, LCLS, FACET, Cryo-EM, AD Test Facilities, ATLAS, and many others) will have their own approval process to come on site.  Please see the user facility sites   for details.  Check with your User Facility Point of Contact to understand all requirements. 

COVID-like symptoms   must be reported to your POC. Daily health symptom tracking is optional - note that most external (non-Stanford) users complete health check thru the user portal   rather than the Stanford Health Check. COVID-19 testing while on-site at SLAC is optional for all users, please bring your own rapid antigen test kits from home (if you are from the United States, you can generally pick some up for free at your pharmacy with your insurance information), or get a PCR test from available locations in the Bay Area (sort by zip code 94025, filter for free testing locations).

If you test positive for COVID or are experiencing COVID-related symptoms contact your Point of Contact (POC) and do not come on site to SLAC (if you are in the Guest House, stay in your room and notify the Guest House manager). POCs should then notify covid@slac.stanford.edu with 'secure' in the subject line.

Course 100R  : COVID-19 Training is recommended but optional for users. See your User Facility webpage for other required core training or check with your Point of Contact.
