About two dozen individuals were exposed to an unknown substance at Ross Correctional Institution in Chillicothe Wednesday morning.
The Ohio State Highway Patrol Lt. Robert Sellers said late Wednesday morning that 24 individuals including correctional officers, nurses and inmates had been exposed and no fatalities had been reported.
Several EMS units from Pickaway County were dispatched to the scene to provide transportation to hospitals.
Those affected have been transported to Adena Regional Medical Center for treatment.
Sellers said the prison is currently secure and has 300 doses of Narcan on hand if needed. The contaminated cell block has been cleared and all persons from the contaminated area have been temporarily relocated within the facility. A hazardous material decontamination team is en route for cleanup.
According the Ross County Correctional Institute page of the Ohio Department of Correction website, the institute has 1,926 inmates with a total staff of 494 as of last week.
Sellers noted the incident is still under investigation. The Circleville Herald will continue to follow the story.
