Hazmat crews called to investigate chemical leak at Trumbull building

State Hazmat crews are investigating the cause of a chemical leak that brought three dozen firefighters to a Trumbull building Tuesday.
It happened at the Data Center located at 60 Merritt Blvd.
Officials say crews were called after an employee began to feel eye and throat pain.
They say the problem was traced to a pump feeding a cooling tower on the roof.
News 12 is told a small amount of a corrosive chemical leaked, but there were no serious injuries reported.
