Harris Nuclear Plant Siren Testing

Sirens are the primary outdoor warning system for alerting the public of an emergency.  In the unlikely event of an emergency at the nuclear plant, Duke Energy would immediately notify federal, state and local authorities. These authorities could activate pole-mounted sirens located throughout the plant’s 10-mile EPZ.

If you hear a loud, steady sound coming from one of the sirens around the nuclear plant, tune to a local radio or TV station. These stations will carry an emergency alert information (EAS) message from local officials to give you information and instructions on what to do.

Remember, hearing a siren does not mean you should evacuate. It simply means to tune to a local radio or television station for information. If sirens are sounding and you do not see or hear a message on radio or television, contact your county’s emergency management office.
 
To alert people indoors, radio and television stations will carry emergency information messages from local officials. Follow their instructions. Stay tuned. Remember, outdoor sirens will not necessarily be heard inside homes or businesses.

In an emergency, fire, police and rescue units may also patrol the affected area and sound their sirens, if necessary. Boaters also would be alerted via sirens, loudspeakers, etc.

Please note: Regularly scheduled siren testing takes place on Wednesdays. Additional testing may occur at other times as part of ongoing maintenance.
