Ohio State Extension is warning producers to stay vigilant about preventing hay barn fires as Mother Nature continues to bring excess rain.

Wet hay can spontaneously combust when internal bacteria cause temperatures to rise. Once hay reaches 175 degrees Fahrenheit, barns are at serious risk of fire.

Experts say hay stored at more than 20 percent moisture should be monitored closely. They recommend using a probe or sensor to check stack temperatures and warn against moving overheated bales without fire crews on standby.
