One worker suffered minor burns yesterday in a flash fire at the Prairie Ethanol plant near Loomis.

Workers on the scene controlled the fire with an extinguisher.

Firefighters from Mitchell and Letcher then scanned the area with a thermal imager to make sure that the flames were out.

Captain Paul Morris of the Mitchell Fire Department says fighting an ethanol fire is challenging because the flames are nearly invisible when pure ethanol is burning.

Officials from Prairie Ethanol plan to bring in a team of experts to determine the cause of the fire.
