Here in tornado country we have sirens that are used to warn of tornados. They're controlled by the county. They test them every Wednesday afternoon. You're supposed to tune in to news to find out what's going on. They're just an alert to tell you something (usually a tornado) is going on. They also were to be used in case of atomic attack. If you hear the siren you're supposed to seek shelter and then tune in to find out what's going on. This is an effective way for dealing with any emergency, even outside of tornados.
