MIAMI COUNTY — Firefighters had a busy day on Saturday.

Between midnight and 6 p.m., four separate and unconnected fires were fought by area departments.

Shortly after midnight, Casstown and Elizabeth Township fire companies were dispatched to a farm on North Hufford Road, south of Casstown, for a fire involving multiple semi-tractors.

Quick work by firefighters kept the blaze from spreading to a nearby barn. Damage was contained to the trucks.

A mid-morning fire in the 400 block of East Franklin Street in Troy displaced four families in an apartment building. Troy firefighters were on the scene for nearly two hours fighting the fire on the second floor of the brick home. There were no injuries, but the Miami County Animal Shelter was contacted to care for a cat.

On Saturday afternoon, a mobile home fire on U.S. Route 40 saw the Bethel Fire Department, along with neighboring departments, on the scene of a fire that destroyed one mobile home.

Fletcher firefighters were dispatched to a reported barn fire on East U.S. Route 36, at the outskirts of Fletcher, just after 6 p.m. Firefighters arrived to find a large barn fully-engulfed. Casstown, JSP (Johnson/St. Paris), Christiansburg, Piqua, and Lockington provided mutual aide.

Chief Tony Bensman of the Fletcher Fire Department said the likely cause of the fire was a heat lamp that was being used to keep chickens warm. Seven chickens died in the fire.

There was one report of a firefighter treated for smoke inhalation at the Bethel Township fire. No other injures were reported.
