A fire broke out in the Kershaw Correctional Institution woodworking shop Tuesday afternoon. Lancaster County Fire Marshal Russell Rogers said the fire started in the dust-collection system in the woodworking shop, located in the back part of the prison complex. The fire started shortly after 1 p.m. and was extinguished by the built-in sprinkler system. The cause of the fire is still unknown, Rogers said Tuesday. There were inmates and officers in the building at the time of the fire and one of the inmates sustained a minor burn injury, Rogers said.
