Abstract: At 7:30 a.m. on February 24, 2017, Employee #1 was working as a full-time employee for a framing contractor. He was at a new residential construction site and he was outside pushing a wheel barrel air compressor. He was at location Phase 3, on the ground level. A coworker was driving a Gradall Model Number 544D-10W all-terrain forklift. Its backup alarm was sounding. The coworker did not see Employee #1. Employee #1 was wearing his reflective vest under his sweatshirt. Employee #1 was struck by the right rear tire of the Gradall and knocked to the ground. His legs were run over by the Gradall's tire. He sustained serious leg fractures and required hospitalization for greater than 24 hours. Employee #1's immediate supervisor was on the job site at the time of the incident. The employer reported the serious injury in a timely manner. DOSH learned of the accident that same day. The Division was notified on February 24, 2017, by both emergency services and the employer that an employee had sustained a serious leg injury. No serious accident-related citations were issued as a result of the investigation.
