The evacuation of a northern Iowa town due to a chemical fire has ended and residents are now free to go home.
A fertilizer plant at Northwood’s municipal airport caught fire Thursday morning. The plant contained sulfuric acid and after at least four people complained of breathing problems, the town was evacuated.
Residents were taken to a community center in the nearby town of Kensett. About 250 to 300 people were at the community center during the evacuation.
Highway 65 through town and up to the Minnesota border was shut down because of the worry fumes from the fire would cause more breathing issues.
Around 3:00 p.m. officials declared it was safe for residents to go home. Tests showed there was no danger.
