COVID-19 Health and Safety Protocols for Visitors

Argonne is committed to helping protect the health and safety of those who visit our site. Information below applies to visitors who are not using one of the Laboratory’s scientific user facilities. Users of the Advanced Photon Source, Argonne Leadership Computing Facility, Argonne Tandem Linac Accelerator System and Center for Nanoscale Materials should refer to User Facility Registration.

All individuals must:

Provide proof of COVID-19 vaccination. Argonne accepts printed or digital copies of all vaccines approved by the World Health Organization.
Provide negative results from a COVID-19 test conducted within 72 hours of site access. User will receive a gate pass valid for up to three days, based on the date of the test result and approved visit duration.

If a user’s approved visit duration exceeds the expiration date on the gate pass, the user will need to take another COVID-19 test and provide proof of a negative result at the Argonne Information Center to renew the gate pass.

Argonne will accept printed or digital test results from either a polymerase chain reaction (PCR) test or a rapid antigen test performed by a health care provider no more than 72 hours prior to entry. Results from at-home testing kits do not meet Argonne standards.

The above conditions are subject to duration of exemption.

Argonne does not require booster shots for any COVID-19 vaccines at this time.

The laboratory will continue to update its site access policies based on the evolution of the COVID-19 pandemic.

Follow all safety protocols posted by the Lab, including guidance on face coverings and social distancing.

Respect capacity limits in meeting rooms and other public areas.

If you become ill while on site, stay away from others and immediately call the COVID-19 Question Line. The phone number will be provided to you on a lanyard card when you receive your gate pass. If you become short of breath, call 911 immediately.

Argonne has invited its employees to join in a commitment to take care of themselves and others by following simple health guidelines to prevent the spread of COVID-19. Visitors are also encouraged to read and commit to the Argonne Health Pact.

  • The Argonne Information Center is where you’ll get the identification badge you need to access the laboratory site.
  • Argonne is dedicated to protecting visitors to our campus. Every visitor watches a two-minute training video about how to protect oneself and others while on campus.
