A massive explosion at a chemical plant in Georgia caused a huge plume of smoke, and authorities have instructed residents and businesses to shelter in place.

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

Some residents east of Atlanta were evacuated while others were told to shelter in place Sunday to avoid contaminants from a chemical plant fire that sent a massive plume of dark smoke high into the sky that could be seen from miles away.
