| Title | Offsite Notification Due to Inadvertent Activation of Emergency Sirens |
| Event Description | The following information was obtained from the licensee via facsimile:
At 0912 [EDT] the Salem Township sirens, zone 14, sounded for 3 minutes. All ten sirens in zone 14 sounded. The reason for the siren sounding was unknown at that time. The Sheriff Dispatcher notified Emergency Preparedness of the sirens sounding. Emergency Preparedness called the vendor, Transco, to investigate the siren sounding. Transco went to the 500 [foot] siren tower and polled the siren system and found that the Zone 14 sirens had been activated by a signal from the Sheriff Dispatch office at 0912 [hrs.]. Transco then went to the Sheriff Dispatch office to look at the system and found no problems. At 1158 [hrs.], on 5/8/04, a quiet test, e.g. low noise level test, was conducted for siren 91, next to the Sheriff's office, to ensure the siren system was operating properly. Discussions with the Sheriff Dispatchers indicated that they were not in the vicinity of the siren console and did not have the siren screen called up. Therefore, it was not possible for the Sheriff Dispatchers to inadvertently activate the sirens. The only other activity in the siren console area was an exterminator working. Therefore, at this time, the most likely cause of the sirens sounding is the exterminator inadvertently activating the Zone 14 sirens. The Prompt Notification System (sirens) were verified capable of performing [their] intended function (operable), at no time was Emergency Notification capability impaired, it was also validated, that once activated by the inadvertent action, the system responded as expected. This spurious activation does not appear in any way to be related to Event #40734 regarding the test failure on May 7, 2004. The licensee has notified the NRC Resident Inspector. |
