(KMOV) -- Fire fighters in the Pattonville district are dealing with a chemical spill Thursday night.
Authorities said crews shut down the intersection of Smiley Ave. and Old St. Charles Road. The container is said to be a one gallon container of some sort of fuming acid.
Firemen said they believe the container fell off a truck passing through. There have been no reports of injuries no evacuations, but people are being kept away.
There are no markings on the container so crews don't know what exactly they are dealing with.
