HILLSBORO, Ill. (WRXX) – The Illinois Department of Corrections said the suspicious substance found Wednesday at Graham Correctional Center has been identified as nonhazardous and should not have necessitated the use of Narcan or required hospitalization.
Eighteen prison employees were hospitalized and received Narcan after reporting symptoms similar to those of a toxic exposure.
However, according to Illinois State Police (ISP), they tested suspicious materials from the scene and the tests came back negative for narcotics or hazardous materials.
Tests showed a nasal spray at the scene contained Acetaminophen and a powder was found to be baby powder containing Aluminum Phosphate, Ethylpyrrole, and Benzene.
ISP is conducting additional testing on clothing items today as well, officials said. Everyone involved in the incident has been discharged from the hospital.
