On July 22, 2015, an employee was working inside a trench box, attempting to place dunnage under one side of the trench box to protect utility lines. The excavator bucket was used to lift one end of the trench box so dunnage could be placed underneath that section. The bucket unexpectedly released from the boom of the excavator as it raised a portion of the trench box. The bucket fell into the trench box, striking and crushing the employee who was hospitalized and had several surgeries.
