The Georgia Poison Center has set up a hotline for calls relating to air quality. This comes days after thousands were displaced after a chemical fire broke out Sunday morning at the Biolab facility on Old Covington Highway in Rockdale County.

GWINNETT COUNTY, Ga. — People in multiple counties are now reporting a chlorine smell and smoke spreading after a chemical plant fire in Rockdale County. A fire broke out Sunday morning at the Biolab facility on Old Covington Highway. Rockdale County remains under a shelter-in-place order.

Rockdale County is asking residents once again to shelter-in-place due to a plume banking down in the county. The new alert comes hours after the county had lifted a previous shelter-in-place order for a fire that broke out at the Biolab chemical plant on Sunday.

Gwinnett County leaders say multiple tests of air quality have shown no significant concerns, despite complaints about lingering smoke and odor from the Biolab fire in Rockdale County.

Thousands of people were evacuated Sunday when a chemical plant fire sent a large, hazardous plume of smoke into the air about 30 miles east of Atlanta. It's unclear when residents can return home.

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