STRUTHERS, Ohio - Two men are in critical condition at a Pittsburgh burn unit following an explosion at a sewage treatment plant.
Investigators are still trying to find out how it all happened.
Just after 2:30 p.m. Thursday afternoon fire crews responded to an explosion inside the Struthers sewage treatment plant.
They found two men inside badly burned.
They were quickly Life Flighted to Mercy Hospital in Pittsburgh for treatment. They've been identified as Gary Wilson and Kenny Stiver.
According to calls on emergency radio the men were suffering from second degree burns.
No visible fire damage could be seen on the outside of the buildings.
Lowellville Avenue was shut down for a couple hours since fire crews feared some of the methane gas was still present and another explosion was possible.
But by 5:00 p.m. the road re-opened and fire investigators arrived at the scene to try to determine a cause.
A methane gas conversion system opened at the location last October; its purpose is to turn methane gas into electricity and heat energy. It was built through a $5.4 million stimulus grant.
The facility was to save the treatment plant over $100,000 a year in operating costs.
Fire and police departments wouldn't respond to our calls for information about the incident.
