Officials say an explosion in a tank at a wastewater treatment plant in Michigan has left one man dead and another injured.
AnnArbor.com and the Detroit Free Press report methane gas exploded on Monday afternoon while the men were working on a holding tank at the facility in Dexter, located in Washtenaw County about 40 miles west of Detroit.
Dexter Area Fire Department Chief Loren Yates says both men were believed to be inside the tank when the explosion occurred, and investigators suspect that the men's torches ignited the gas. Yates says one of the men may have been thrown from the tank by the explosion.
The injured man last was listed in stable condition. Officials say the work is part of a $3.3 million project. Authorities are investigating.
