MT. VERNON — Several fire departments in Jefferson County reportedly responded to a fire Sunday night at Continental Tire in Mt. Vernon.

Reports indicate the fire happened in an HVAC unit on the roof above the Passenger Tire Curing Department.

Some workers who showed up for the third shift in that department were told to go home, while those who were inside already working were reportedly told to stay.

No injuries have been reported, but some employee relatives say their loved ones were taken to the hospital via ambulance.
