Georgia chemical lab fire prompts road closures and evacuations

A fire broke out at a chemical plant just east of Atlanta Sunday, prompting officials to ask residents in the area to evacuate.

At around 5 a.m., a sprinkler head malfunctioned at the BioLab plant in Conyers, "causing a mixture with a water reactive chemical," according to Rockdale County Fire Chief Marian McDaniel.

"There was a small fire on the roof, which has been contained, but at that time, right now, there are no other issues," McDaniel said.

The fire department is working on removing the material from the building and the water source, McDaniel said a press conference Sunday.

Rockdale County officials told residents living between Sigman Road and Interstate 20 to evacuate Sunday morning. Those living north of Sigman Road were advised to shelter in place. Churches in the area were advised to cancel services.

It's not clear if there are any injuries at this time.
