Clermont County says malfunction caused emergency sirens to sound inadvertently

CLERMONT COUNTY, Ohio - A transmitter malfunction caused hazard warning sirens to sound inadvertently in Clermont County Thursday morning, a county official said.

John Kiskaden, director of the Department of Public Safety Services, cited a malfunction of the siren transmitter at the Union Township Communications Center. Kiskaden said technicians are trying to determine why it malfunctioned and how to prevent future accidental activations.

The sirens went off about 10:15 a.m.  An announcement was immediately distributed to inform the public that there was no emergency.

Warning sirens in Clermont County are supposed to be activated when:

A tornado warning is issued by the National Weather Service;
A tornado or funnel cloud is reported by a public safety official or trained weather spotter;
A chemical emergency has occurred resulting in a shelter-in-place order to be issued.

The purpose of the outdoor warning system is to send people indoors to get information from other sources. The sirens are not intended to alert people indoors, the county said. 

The county recommends that each residence, business, school and church purchase weather alert radios that are automatically activated during severe weather and hazardous materials events. 

Text and e-mail alerts are available through the Clermont County Division of Public Safety Services at or the National Weather Service at
