A couple workers at Bass Pro Shops in Springfield have minor burns after a small gun powder fire this morning.
Firefighters were called to the Cherokee side of Bass Pro, off of Campbell around 6:30 this morning.
The Springfield fire chief says it happened when workers were doing maintenance in the basement.
Crews say the two were burned when gun powder went off in a rifle tube.
Workers were first evacuated from the building. They were allowed back inside around 7 a.m.
A fire marshal was called to the scene to investigate.
