People in the northern part of Rockdale County were ordered to evacuate and others were told to shelter in place with windows and doors closed.

Federal officials are investigating what led to the fire and how it has been handled. The sprinkler system showered water onto water-reactive chemicals around 5 a.m. Sunday, Rockdale County Fire Chief Marian McDaniel said. There were employees inside the plant, but no injuries were reported.

A fire at a chemical plant in Conyers, Georgia, on Sunday caused residents to evacuate or shelter in place in an effort to avoid exposure to a chemical plume, and shelter-in-place mandates remained in place Monday morning.
