Crews responded to a reported hazmat situation in Wilton Tuesday night.
Around 7:50 p.m., officials received a report that a highly flammable chemical had been spilled inside an industrial building at 4300 Route 50. When crews responded, they evacuated a church across the street, and closed Route 50 in both directions at Jones Road and Edee Road.
It was later found that the spill was a less hazardous chemical.
Two workers were inside the building at the time. They were evaluated by Wilton EMS and were found to be okay.
