A Westmoreland County man is the second worker to die from injuries suffered in an accident at a natural-gas operation in West Virginia, says the Pittsburgh Tribune-Review.
Raymond Miller, 43, of Jeannette died Monday afternoon in West Penn Hospital in Bloomfield, where he was flown after being burned on Thursday at the Eureka Hunter Pipeline operations near Wick, W.Va., about 60 miles south of Wheeling, a spokesman for the Allegheny County Medical Examiner's Office said.
A second worker, Bruce Phipps, 56, of Marietta, Ohio, died Friday night in West Penn of burns, the medical examiner's spokesman said.
A third person was injured, but the Tyler County Sheriff's Department said it had no information on that worker.
Eureka's parent, Magnum Hunter Resources, said it was a flash fire at a “pig receiving station.” Pigs are devices used to clean out or to inspect pipelines.
Magnum says initial reports indicate that natural-gas liquids ignited in tanks during “pigging” operations and fueled the fire.
