The Mitchell Fire Department responded to a Mitchell business on Thursday afternoon. Mitchell Fire Marshal Shannon Sandoval says the call came in at 1:44 PM from Bailey Metal Fabricators at 807 North Rowley.  Initial reports were of smoke inside of the building coming from a dust collection unit outside of the building.  Bailey evacuated their employees from the building.  Sandoval says the filters in the dust collection unit ignited, causing the smoke.  There were no visible flames, just heat and melting according to Sandoval.  About a dozen firefighters were on scene for around 45 minutes. No one was injured in the incident.
