Abstract: At approximately 11:45 a.m. on September 9, 2016, three employees were upgrading a sewer line from a 4 foot to a 6 foot main line. Employee #1 and a coworker were working inside the trench leading from the driveway of a residence using shovel to move loose dirt from under the pace pipe. The trench was at least six feet deep when it collapsed. Employee #1 was standing on the west side of the trench facing the right side of the trench wall. Employee #1 noticed that the trench wall was about to cave-in and pushed the coworker out of the way. Employee #1 became engulfed and pinned from the chest down and sustained blunt force trauma to the body resulting in a fractured neck and severed cervical spinal cord, subarachnoid hemorrhage with contusions and abrasions. The employee was killed from their injuries. The trench was about 2 feet wide and about 23 feet long. The depth of the trench was in excess of 6 feet deep. A trench box was located in the yard at the time of the accident and the protective system was not able to fit in the trench.
