Sirens are primarily used in this region to alert residents of emergencies at nuclear power stations, as well as at some college and university campuses, industrial and government facilities and military installations as a warning mechanism for various emergencies, including tornado warnings.
The warning sirens around the Surry Power Station are tested quarterly (typically on the second Wednesday of March, June, September and December). During these routine tests, the alerting signal produced by the sirens is a steady tone that lasts for three minutes. The alerting signal for an actual emergency will be 4 separate 3-minute activation's, each separated by 1 minute of silence.
The warning sirens located at college and university campuses, industrial and government facilities and military installations are periodically tested. These tests are typically publicized by local media sources prior to the actual date of the test.
