Abstract: At 1:00 p.m. on April 21, 2021, an employee working as a courier and part time supervisor for a multinational delivery service was waxing a slide in the "Sec D" area of the facility. The employee turned the conveyor belt off before climbing onto the slide and spraying it down with wax. While climbing down from the slide, he slipped and hit his upper left arm on one of the side panels. Coworker #1, who was working in the same area, witnessed the incident. Coworker #2, the immediate supervisor and full-time operations supervisor, was present onsite and was on a walk at the Door 156 when the incident occurred. The employee fractured his left arm and was hospitalized for 3 days. He underwent surgery followed by physical therapy.
