Visiting Argonne

Updated 10/14/2021

Argonne is a multidisciplinary science and engineering research center, where talented scientists and engineers work together to answer the biggest questions facing humanity, from how to obtain affordable clean energy to protecting ourselves and our environment. To help slow the spread of COVID-19, access to Argonne’s Lemont, Illinois campus is currently limited. Please ensure that you have been approved for access before traveling to Argonne.

When You Arrive

COVID-19 Health and Safety Protocols for Visitors

All essential business visitors must be approved by Argonne’s Chief Operating Officer and the Argonne Site Office. Please confirm with your host that your visit has been approved prior to arriving to Argonne.

All individuals must:

  • Sign a form attesting to their COVID-19 vaccination status. (Visitors may sign the form when they arrive or download the form, sign it, and bring it with them.)
    • A visitor who attests they are fully vaccinated will receive a gate pass valid for their approved visit duration.
    • A visitor who attests they are NOT fully vaccinated or declines to respond must present results of a negative COVID-19 test less than 72 hours old before being issued a gate pass. The gate pass will be valid for up to three days, based on the date of the test result and their approved visit duration.

If a visitor’s approved visit duration exceeds the expiration date on the gate pass, the visitor 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 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. COVID-19 testing for visitors is not available on site.

  • 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.
