A hazmat crew is investigating Monday afternoon after five employees at Lewis Prison reported adverse reactions to a substance found in a cell, the Buckeye Fire Department said. Firefighters responded to the prison a little after 2 p.m. in response to reports of guards in close proximity to the cell feeling lightheaded and vomiting. A total of five Department of Corrections employees reported feeling the effects, firefighters said. Two were treated on the scene and three were taken to a hospital to be evaluated, Buckeye Fire said. Firefighters said no inmates reported any effects from the substance. The inmate who was in the cell was transferred to a different cell as crews investigate.
