Abstract: At 1:00 p.m. on April 11, 2017, an employee was working from an aerial lift to pressure wash a residence. After washing the side of the residence, the employee maneuvered the aerial lift, with its boom extended, up the driveway toward the garage. The basket of the lift struck a height level warning sign, resulting in the employee sustaining broken ribs and abrasions to his back. A coworker witnessed the incident and contacted emergency services and worked to release the employee from being pinned between the basket and the sign. The employee was taken to a nearby hospital, where he received treatment for his injuries.
