(KMOV)-- Hazmat crews in North St. Louis County had to rush to clean up a dangerous chemical spill.
This happened Thursday night on Old St. Charles Road and Smiley.
Crews had to shut down the intersection for one hour to clean up the mess.
Authorities said this all started when a drum carrying chemicals fell off the back of a truck. Crews checked the container but there were no labels to describe what the drum contained on the inside. Firefighters said the container carried some type of fuming acid.
There were no reported injures. The Pattonville Fire Protection district was one of the first to respond.
Authorities said they are still looking for the driver of the truck.
