Authorities lift evacuation order for Iowa town
Authorities allowed residents of a small Iowa town to return to their homes on Thursday hours after they were told to evacuate because of a fire involving sulfuric acid at a local airport.
The entire population of about 2,000 people living in Northwood were ordered to leave town after the fire broke out around 7:30 a.m. CT in a storage shed for sulfuric acid and other chemicals at the airport, said Sgt. Scott Bright of the Iowa State Patrol. Residents were told to go Kensett, Iowa, about 6 miles south of Northwood.
Officials lifted the evacuation order around 3:00 p.m. CT after conducting environmental tests, Bright said.
Four people living in the area went to a hospital with respiratory concerns, Bright said. He added the cause of the fire remains unknown.
