Firefighters were dispatched to a fire at Wellman Industries on Kingsburg Highway in Johnsonville, just after 3:00 Sunday afternoon.
The fire started inside a 90 foot tall silo after a piece of equipment malfunctioned, according to Johnsonville Fire Chief Kerry Tanner.
Tanner says crews managed to contain the fire to the silo and it is under control.
Firefighters will continue to monitor it to make sure it doesn't rekindle.
The silo contained a fluffy plastic product, according to officials.
Tanner says he isn't sure how much of the product burned.
Williamsburg County and Hannah-Salem Fire Departments assisted Johnsonville in the fire.
