Unlike outdoor sirens, all-hazards radios save lives by alerting people who are indoors when severe weather approaches. They can also alert people in homes, schools and businesses to other types of emergencies.
These radios provide constant, useful and up-to-date weather information. They are equipped with a special alarm tone that will sound an alert and give immediate information in a life-threatening situation.
During an emergency, the National Weather Service will interrupt routine weather radio programming and broadcast a special tone that activates weather radios, by county, in the listening areas.While they are primarily used for severe weather alerts, authorities can also use these radios to issue warnings about other types of hazards, such as chemical spills or biological hazards. The hearing and visually impaired can also get these warnings by connecting weather radios to other attention-getting devices such as strobe lights, pagers, bed-shakers, personal computers and text printers.
