Authorities on Monday night ended a shelter-in-place order for more than 90,000 people east of Atlanta following a weekend chemical plant fire that sent a massive plume of dark smoke into the Georgia sky and led to complaints about a strong chemical smell and haze.

Some residents east of Atlanta were evacuated and others told to shelter in place after a fire at a chemical plant. Fire Chief Marian McDaniel told reporters that a sprinkler head malfunctioned around 5 a.
