The Dalton Fire Department is on scene at MFG Chemical on Callahan Road responding to a chemical explosion call. The call was reported at 8:50 am.
There are no reports of serious injuries at this time. 27 people who were in the surrounding area were transported to Hamilton Medical Center for decontamination. Others were decontaminated on site.
At this time there is no evacuation or danger to the public in the area. Residents within a half mile of the site were initially advised to stay in their homes, but that advisory has since been lifted.
