A semi driver suffered significant burns in an explosion inside his rig in Duluth.
Assistant Fire Chief Erik Simonson says waste oil was being transferred when a pump inside the semi backfired, igniting the collection of vapors Tuesday afternoon. KSTP sister station WDIO-TV says the semi is from Rainy Lake Oil in International Falls.
Simonson says the driver suffered substantial second-degree burns to his upper torso. He was taken to a local hospital. His condition was not released.
