Oak Ridge, TN (WOKI) – Personnel will be performing preventive maintenance on the public warning siren system in the Oak Ridge area throughout the week of Nov. 3, 2025
During that week, people in the area may occasionally hear audio from individual sirens in the vicinity of Y-12 National Security Complex.
The sirens are strategically placed to notify the public in the unlikely event of an on-site emergency that has impacts beyond the site boundary.
In case of an actual emergency on the Oak Ridge Reservation, sirens will sound simultaneously with the standard three-minute tone. For more information about what to do in the event of an emergency, please visit the Y-12 website (www.y12.doe.gov/about/emergency-public-information).
