A hazardous chemical fire at a Conyers plant closes I-20 and forces evacuations, marking the third major incident in seven years.

Officials were asking people to avoid the area and evacuate or stay inside to avoid any exposure to chemicals.

People in the northern part of Rockdale County, north of Interstate 20, were ordered to evacuate and others were told to shelter in place with windows and doors closed. Sheriff’s office spokesperson Christine Nesbitt did not know the number of people evacuated.
