A call made to Bryan Grissinger, the Wintermyer job superintendent that day, was not returned Friday.
Linda Hadley, human resources manager for Wintermyer, did not return a call Friday.
In its reports about the three violations found in connection with the accident, MOSH said that "frequent and regular inspections of the job sites, materials and equipment were not made by a competent person(s) designated" by Wintermyer, the employer "permitted employees who were not qualified by training or experience to operate equipment and machinery" and the employer "did not instruct each employee in the recognition and avoidance of unsafe condition(s) and the regulation(s) applicable to his work environment to control or eliminate any hazard(s) or other exposure to illness or injury."
According to the report, Wintermyer employees were performing horizontal boring and installing underground fiber-optic cable conduit along the road that day. When employees approached a Vermeer D55x100 Navigator Horizontal Directional Drill to remove a rod box, which is hoisted on and off the directional drill by a boom truck, they did not follow the operator's manual's procedures for removing the rod box, which contained rods weighing about 270 pounds each, and two of the workers were killed, according to the report.
As part of the MOSH investigation, Grissinger, who said he helped remove the rod box, wrote his recollection of the events that day in an interview statement.
"There was no formal training on the drills from Wintermyer," he said.
When Grissinger was asked to describe in detail how to remove a rod box, he wrote: "I don't know the correct steps. This is the first time I've supervised the use of this equipment."
He said he had "no clue" whether the engine of the machine was running when the employees attempted to move the box, according to the report.
The MOSH investigator, in his report, said he found the operator's manual, which provided a "very simple six-step procedure for rod box removal," inside the drill operator's cab.
