Lincoln firefighters were called to the UNL Campus around 10:30 Tuesday morning where contractors were working in the university’s underground tunnel system.
“Apparently, one of the workers inadvertently opened a steam valve,” says LFR Captain Nancy Crist. She says the pressure out of the valve was 250 pounds per square inch and was about 500 degrees.
She says the workers were able to use manholes and hatches to get to safety. UNL maintenance staff was able to close the valve and LFR crews searched the tunnel system near the building at 820 N. 16th Street where the contractors were working.
