During this test, the sirens will sound at full-volume for approximately four minutes in Westchester, Rockland, Orange and Putnam counties. Because this is only a test, no response by the public is necessary during the siren sounding.
If there were an emergency at the nuclear power plants, the sirens would be sounded continuously at full volume for 4 minutes, followed by an activation of the Emergency Alert System (EAS) on radio and television stations to broadcast important information and instructions. The sirens are not a signal to evacuate, rather they are intended to alert the public to tune to this or another EAS radio or TV station for important information.
