Martin County’s Emergency Management Agency, the St. Lucie County Department of Public Safety, and Florida Power & Light (FPL) will perform maintenance on the outdoor warning sirens for the St. Lucie Nuclear Power Plant.

Sirens will be tested between 8 a.m. through 5:30 p.m., Monday, Feb. 8 through Friday, Feb.12.

The maintenance will involve visual inspections, as well as a 20-second air-horn sounding of individual sirens.

Before and after the sirens sound, a message will be broadcast on the sirens’ public-address system stating, “This is only a test.” FPL and St. Lucie and Martin counties regularly test the siren system to improve public awareness of its function and ensure its operability.

The 1,132-acre St. Lucie site consists of two nuclear units located on Hutchinson Island on A1A between Stuart and Ft. Pierce.

In the event of an actual emergency at St. Lucie plant, the sirens would sound for at least a five-minute period. Official instructions or information would follow on local radio and television.
