Abstract: At approximately 8:20 a.m. on March 20, 2013, Employee #1 was driving a grounding stake into the ground using a fence post driver. As he drove the stake into the ground, the driver contacted his left thumb and crushed it. Employee #1 sustained severe thumb injuries, including lacerations. He was transported to a medical center, where he underwent surgical procedures and was then hospitalized for postoperative care. The accident causal factors included a lack of procedures and scheduled periodic inspections for identifying and evaluating work place hazards as well as the use of inappropriate hand tools for the job.
