Welding sparks cause Evanston hospital fire

Fire officials say a blaze at an Evanston hospital was caused by welding sparks.

Thomas Janetske, division chief of the Evanston Fire Department, says damage was limited to an area under construction at Evanston Hospital.

He says patients were never at risk, and no injuries were reported. About 100 workers were evacuated.

Janetske says firefighters arrived at the hospital Monday afternoon to find heavy smoke and fire on three floors of the new building.

The fire was extinguished within several minutes.
