Emergency Information

Current Status: Laboratory Operations are normal. All employees should report to work for their assigned shifts.


Employees should check this page for information in the event of an operational emergency or other change in operations at Argonne.

Non-emergency information and directions for employees will be posted here by laboratory senior management, the U.S. Department of Energy and emergency responders.

The Argonne Info Line at (630) 252-INFO (630-252-4636) is also updated when severe weather affects Argonne operations.

Employees can also be notified of changes to the laboratory’s operations — for example, a delayed opening due to a heavy overnight snowfall — via the "Argonnestatus" account on Twitter.The account can be set to automatically send text messages to most mobile phones and PDAs.

Site Alarms

Several types of alarms alert you to emergencies on the Argonne campus:

  • Outdoor sirens mean take shelter immediately.
  • Site-wide public address system warnings are preceded by a 20-second tone. Listen to the warning message that follows the tone.
  • Building alarms, such as bells and strobe lights, will announce building-specific emergencies. Listen for a building-specific message to immediately follow the alarm. If no message follows immediately, evacuate the building and report to your assigned accountability location. Localized or individual building public address warnings delivered by the Area Emergency Supervisor will not be preceded by a tone.

Check with your Area Emergency Supervisor for specifics for your building. Outdoor sirens are tested the first Tuesday of each month at 10:00 a.m.

Tornado Shelters

Tornado shelters are available and marked with signs throughout the site. If a tornado watch has been issued, identify the location of your nearest shelter. If a tornado warning is issued, go to shelter immediately, and stay there quietly until an all-clear is issued. Check with your Area Emergency Supervisor regarding shelter locations.

Evacuation Routes

Evacuation routes are posted in most buildings. Be aware of at least two evacuation routes from your work area to your accountability location. Check with your Area Emergency Supervisor for your accountability location.

Further Information

Contact your building's Area Emergency Supervisor or the site's Emergency Management Officer at ext. 2-5991 with any additional questions or requests for more information.
