Laramie, WY – Two workers suffered minor injuries in an explosion and fire at a plant near Gillette testing technology to refine low-grade coal into cleaner-burning fuel.
The unidentified workers were treated and released at Campbell County Memorial Hospital after a pressure differential forced open an access door at the plant owned by Evergreen Energy.
Evergreen Energy spokesman Paul Jacobson says the incident occurred yesterday (Monday) at an area of the plant that was undergoing maintenance. He says the cause of the explosion is under investigation.
Campbell Sheriff Bill Pownall says it appears to be a coal dust explosion triggered by a welder on a pipeline.
Jacobson says the incident caused only ``minor damage.''
