Abstract: At 7:51 a.m. on July 24, 2017, Employee #1 and Coworkers #1 and #2, employed by an elevator interiors design and installation company, were unloading eight elevator ceiling tiles, each weighing approximately 100 pounds, from a 24-foot box truck. They loaded the tiles onto a drywall cart and moved the cart onto the truck's lift gate. They attempted to steady and balance the cart as it was lowered. However, when the gate hit the concrete surface, the cart hit the lip of the tail gate, and the ceiling tiles fell from the cart and struck Employee #1. Emergency services were called, and Employee #1 was transported to the hospital. He was admitted and treated for a fractured collarbone.
