Abstract: At approximately 1:00 p.m. on April 7, 2017, Employee #1 was using a wire cup brush on a 120-volt, 15-ampere Metabo W2000 Portable Grinder to remove the paint from the shields. This is a normal task that the squires perform at least once a week or when there aren't many shows. They were behind on maintenance of the shields, so he had been working on the shields the majority of the day. He remembered that he was performing the task of removing the paint from the shields, and the next thing he remembers is being in the ambulance. According to the police report, his hair, which was below his shoulders, became tangled in the tool. The grinder pulled enough tension to split the skin on his scalp. The grinder was missing its guard, but there is no guard required when using a wire cup brush. A coworker summoned emergency medical personnel and Employee #1 was transported to the medical center's shock trauma. Employee #1 does not remember if his hair was tied back at the time, but he generally does tie his hair. He was wearing his combat gloves and goggles at the time of the incident. Employee #1 was also given one-on-one training on the use of the tool. Employee #1 received a depressed skull fracture, which required stitches and 18 staples.
