Warning Sirens

When the sirens sound, you should:

  • Evaluate your surroundings and seek information about the nature of the warning
  • Be prepared to take immediate self-protective action, which may include seeking appropriate shelter or remaining where you are

There are two warning siren systems on the Clemson campus.

Clemson University tone and voice sirens
Sirens are located at Memorial Stadium, Byrnes Hall and the band practice field on Perimeter Road. These sirens are intended to warn people outside campus buildings of approaching severe weather and other emergencies.

In an emergency the sirens will sound a tone and some will have a voice message announcing the nature of the emergency.

Sirens may be sounded for a number of emergencies, including:

  • Tornado warnings
  • Lightning warnings
  • Other natural disasters
  • Gunman or other threat

Oconee Nuclear Station warning sirens
Sirens serve a 10-mile zone around the station north of Seneca. These sirens are located at various locations on campus and throughout the Clemson and Seneca communities.

When they are activated do not attempt to immediately evacuate the area. Check the CU Safety Web page, local media or other information sources for details before taking action.

For more information on what to do in a nuclear emergency, go to Duke Energy's emergency preparedness page.

Warning Siren and CU Safe Alert Tests

Both the campus and nuclear siren and CU Safe Alert systems are tested during the first month of each calendar quarter (January, April, July and October).

Tests will be announced in advance on the Alerts site.
