Fire set off an explosion at a cabinet maker's shop in central Minnesota, and three workers suffered injuries, authorities said.
The incident occurred about 2:15 p.m. Thursday at Schlangen's Custom Cabinets, in Eden Valley, according to the Meeker County Sheriff's Office.
Fire and rescue personnel responded along with sheriff's deputies on the fire call, and the explosion occurred outside the building after they arrived, the Sheriff's Office said.
The blast injured three employees, but all were expected to survive. They were identified by authorities as Duane Stang, 46 of St. Cloud; James Thielen, 57, of Richmond; and Scott Thielen, 39 of Eden Valley.
"The fire and explosion appear to be the result of a piece of machinery causing an ember to be pulled into the venting system, which resulted in the dust explosion," the Sheriff's Office explained in a statement.
