A weekend fire that sent a massive plume of dark smoke into the Georgia sky has led to complaints about a strong chemical smell and haze several miles away across metro Atlanta, where some schools canceled outdoor activities and residents living near the fire sheltered at home.

More than 90,000 residents in a county east of Atlanta have been told to keep sheltering in place a day after a chemical plant fire sent a massive plume of dark smoke high into the sky that could been seen for miles.
