“… Police said the contractors were in a “confined, well-type” area at the Bruce Mansfield Power Station in Beaver County when hydrogen sulfide gas was released early Wednesday. Police said 34-year-old Kevin Bachner and 42-year-old John Gorchock were unable to reach safety and were killed.

Pennsylvania State Police said the workers removed an elbow joint from a pipe, releasing hydrogen sulfide gas, CBS Pittsburgh reports.

“The line was not supposed to be charged, obviously. They got to the last bolt to crack it open and when they did so, this nauseous gas, hydrogen sulfide-type mixture immediately incapacitates you,” State Police Lt. Eric Hermick said.

State police say first responders did all they could to rescue the men that were trapped, but it was too late. …”
