Tuesday at noon, the Emergency Management Agency will be testing tornado sirens around Muskingum County.
EMA Director Bo Keck said they will test all 40 sirens so the public can become familiar with the sound and to also make sure they are functioning properly.
"We have spotters at each siren location to tell us whether they worked or not and whenever you're dealing with radio circuits and so forth, you never know if it's going to work," said Keck.
He said the sirens are only activated if there is a tornado warning or if one has been spotted in the area. The devices are designed to alert people outdoors.
"We have people that will normally call and say they didn't hear the siren and well we'll ask them where they're at and they're in their house or working in a business, but the sirens aren't made for that," he said.
The sirens will be tested every Wednesday from now until next November, weather permitting.
