A chemical leak led to the closure of several streets and home evacuations in Columbia Thursday night.
The 3700 block of North Main Street was closed between Sunset Drive and Monticello Road due to a leak of hydrofluoric acid, Fire Chief Aubrey Jenkins said.
Homes within two blocks of the Quaker Chemical plant on Elmore Street were evacuated while others were told to stay inside, Jenkins said.
A person who saw the chemical cloud was taken to an area hospital after complaining of a burning sensation. Some of the firefighters responding to the scene were also taken to the hospital for evaluation.
Jenkins says the chemical cloud has dissipated.
