ROCHESTER, N.Y. — If you were driving over the Freddie-Sue Bridge in Rochester and saw fire trucks below, there was no emergency. It was a training exercise.

The Rochester Fire Department's technical rescue team was conducting a confined space drill. The yearly drill was done with the state Department of Transportation as part of its biennial inspection of the Frederick Douglass-Susan B. Anthony Bridge over the Genesee River.

"This bridge is one of thousands of confined spaces in the city of Rochester and the greater Rochester area," Capt. Edward Trace said. "People make entry into confined spaces from everything from cleaning to regular work processes. We want to be ready to help somebody if they get into trouble, whether it's a vat or bridge work or the man hole cover in the middle of the road. We want to be able to respond quickly to give somebody a fighting chance at surviving.”

The drill is a simulation of where a person might go if they're working on a construction or cleaning job and are in need of rescue.
