An employee was squatting down adjusting inventories on lower shelves while a coworker was stocking yeti ice chests approximately 16 feet above the injured employee. The yeti ice chests were in cardboard boxes and weighed about 45lbs. The coworker lost their grip on one of the yeti boxes and it fell onto the injured employee knocking her into the shelving and then onto the floor. The injured employee passed out, and sustained a laceration on her left temple. She also suffered a broken right ankle and sustained injuries to her back. The injured employee was hospitalized.
