Residents in Georgia ordered to evacuate or shelter in place after fire at chemical plant

Some residents east of Atlanta were evacuated while others were told to shelter in place to avoid contact with a chemical plume after a fire at a chemical plant.

Rockdale County Fire Chief Marian McDaniel told reporters that a sprinkler head malfunctioned around 5 a.m. Sunday at the BioLab plant in Conyers. That caused water to mix with a water-reactive chemical, which produced a plume of chemicals. The chief said she wasn't sure what chemicals were included.

A small roof fire was initially contained, but reignited Sunday afternoon, Sheriff Eric Levett said in a video posted on Facebook as gray smoke billowed into the sky behind him. He said authorities were trying to get the fire under control and urged people to stay away from the area.
