Outdoor sirens are tested the first Tuesday of each month at 10:00 a.m. Several types of alarms alert you to emergencies on the Argonne campus:
- Check with your Area Emergency Supervisor for specifics for your building.
- 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.
- 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 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.
