When there is an alarm on NWR, the following 4-step procedure is followed:
Only the most imminent life- and property-threatening hazards are broadcasted with the SAME signal and 1050 Hertz warning alarm tone, where the public has to take immediate action to protect themselves and their property. An operational guideline is that messages are alerted only for hazards urgent enough to warrant waking people up in the "middle of the night" or otherwise interrupting someone's activities at any time. The operational use of the SAME signal and 1050 Hertz warning alarm tone is at the discretion of WFOs, situationally-dependent and coordinated with each state's Emergency Alert System (EAS) Plan. |
