Emergency Sirens Test

April 4, 2023 @ 10:00 am - 11:00 am

The Delaware Emergency Management Agency (DEMA) and Delaware State Police will conduct a quarterly test of the Salem/Hope Creek Nuclear Generating Stations Alert and Notification system on Tuesday, April 4, 2023. The sirens will sound at 7:20 a.m.

The 37 sirens located within ten miles of the Salem/Hope Creek (New Jersey) plants will be activated for three to five minutes. The siren tests will be followed by a test message of the Emergency Alert System (EAS) on local radio stations.

Sirens that will be tested are the same sirens used to alert the public in the event of an actual emergency at either the Salem or Hope Creek Nuclear Generating Stations. In such an emergency, the public would be alerted by the sirens to tune their radios to one of the local EAS stations for important emergency instructions.

Any residents living within the 10-mile Emergency Planning Zone (EPZ) may contact DEMA at (302) 659-3362 if they are in need of potassium iodide (KI) tablets. To check whether you live within the EPZ, you can click here
