On Dec. 2, 2015, Adamo’s president and chief executive officer, John T. Adamo, Jr., was killed in an accident at the Muskingum River Plant near Beverly, Ohio, and another worker was seriously hurt, according to the U.S. Occupational Safety and Health Administration (OSHA).
Adamo Jr. was 57 at the time, according to his obituary.
Like Killen, the Muskingum plant accident also happened at 8:30 a.m., online federal records show.
Adamo and another worker were injured during the demolition of a coal conveyor system that spanned the Muskingum River.
“During the pre-burn of a support tower, the tower collapsed whereby the coal conveyor hung from eight 2-inch cables that were attached to concrete buttresses at the cables’ ends. The collapsing tower caused the second tower to collapse and the conveyor fell into the river,” OSHA officials wrote in an Accident Investigative Summary.
