(KNZA)--Fire caused damage at a rural Robinson shop Thursday evening.

The Robinson Fire Department was called to 2629 Thrasher Road shortly before 8:50.

Upon arrival, Fire Chief Dennis Tietjens says heavy black smoke was found coming from the about 40 by 50 foot metal building.

Entry was made and a farm sprayer along with related shop items were found burning.

The fire was quickly extinguished, but Tietjens say the sprayer sustained heavy damage and building heat damage.

Tietjens says an investigator from the State Fire Marshal’s office was called to investigate.  He said the investigator determined the flue pipe that exited the structure was mostly likely at fault.

Assisting at the scene were the Hiawatha Fire Department, Town and Country EMS, Brown County Rescue Squad and Brown County Sheriff’s Department.
