Two warning siren systems are present on the campus of Clemson University.
The Oconee Nuclear Warning Sirens serve the 10 mile planning zone (EPZ) surrounding the Oconee Nuclear Power Plant north of Seneca, South Carolina. The sirens located at various locations on campus and throughout the Clemson / Seneca \ communities serve to notify citizens of a variety of events that may occur at the site. The Oconee Nuclear sirens can generally be heard throughout campus.
The weather warning signs are intended only to warn campus occupants that may be outside of buildings of impending severe weather. They are not intended to be heard through the entire campus, including the interiors of most buildings. The weather warning sirens will be activated whenever severe weather is anticipated to pass through or near the Clemson area and there is sufficient time to process the warning. The siren system is only intended to be an adjunct warning tool. Your best protection is to be aware of possible severe weather in the area, monitor local conditions, and be prepared to act to seek refuge. As weather is very difficult to predict and severe weather may develop suddenly and without notice, the weather warning sirens may not be able to be activated for every occurrence. The outdoor weather warning sirens are located near:
During an actual emergency you may not be able to distinguish between the two systems. Regardless of which siren system is activated the same initial action(s) are indicated:
If severe weather appears to be imminent, immediately seek refuge and shelter-in-place. As soon as possible seek information via local media or other information sources to determine the actual nature of the siren warning.
If the Oconee Nuclear Warning system is activated you should NOT immediately evacuate the area. It is very important to tune to local media and other information sources. Refer to the Oconee Nuclear Site Information guide for assistance.
Both siren systems are tested regularly to ensure they are working correctly. The testing is part of normal maintenance and no public action is necessary.
During siren tests you will hear the siren sounding for 1-3 minutes. During an actual emergency, the sirens would sound repeatedly. Siren tests are normally conducted on the 2nd Wednesday of the first month of each calendar Quarter.
Campus weather warning sirens are tested at 11:00 a.m. for approximately 3 minute. Oconee Nuclear sirens are tested at 11:50 a.m. for approximately 3 minutes.

Hear sample siren. The sample is a good representation of both the nuclear and weather warning sirens. (Siren model is the Federal Signal 2001SRNB.)
