SUBJECT: COVID-19 Update Argonne National Laboratory transitions from Minimum Safe Operations to Limited Operations
To help mitigate the spread of COVID-19 and protect the health and wellbeing of employees, contractors and visitors, Argonne has been cooperating with the stay-at-home order issued by the Governor of Illinois on March 20, 2020. As a result, the Laboratory instituted Minimum Safe Operations where most employees began teleworking while limited staff and essential contractors remained onsite to continue vital work related to research, infrastructure projects and systems continuity. We are thankful to all who helped us make this happen and we know that all our combined efforts made a difference.
As federal, state and local entities proceed with plans to reopen more areas, on June 15, 2020 Argonne will begin moving from Minimum Safe Operations to Limited Operations. During this transition Argonne will gradually begin increasing the number of people on site each day. To help sustain the safety and wellbeing of the Argonne community and everyone accessing the Laboratory, we will continue to employ COVID-19 transmission prevention measures, like social distancing, face coverings and telecommuting. As an Argonne contractor, please note that you're responsible for providing and ensuring your employees have and wear face coverings when they come to our sites.
Determinations on how your work at the Lab will proceed depend upon your continuing communication with your Technical Representative on how you plan to meet the requirements of the Lab. Please don't hesitate to contact them for more information or with any questions.
Argonne will continue to provide new information and updates. We thank you for your attention and encourage you to visit to for more information on how Argonne is managing COVID-19 impacts.
