More than 90,000 residents east of Atlanta were told to keep sheltering in place Monday, a day after the chemical plant fire. The haze and chemical smell had spread to Atlanta by Monday morning, prompting firefighters to use detectors to check the air quality in various parts of the city, Mayor Andre Dickens said.

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.

Tens of thousands of residents in one county were told to shelter-in-place through Monday, the day after the fire.
