Abstract: At 1:30 p.m. on September 25, 2008, Employee #1 entered an unprotected, 9-foot deep trench to replace existing water drainage lines. Employee #2 was operating a backhoe, and Employee #3 was pouring gravel into the trench, while positioned at the top of the trench. During final dig out with a shovel, a large, heavy chunk of soil fell from the face of the trench. The soil struck Employee #1 and trapped him. Employees #2 and #3 entered the trench and began digging Employee #1 out from under the chunk of soil. The local fire department was summoned and arrived to complete the removal of Employee #1 from the trench. Emergency medical responders were called, and Employee #1 was taken to the emergency room at Fairview Hospital. He was hospitalized for treatment of his injuries. Employee #1's injuries included a fractured pelvis and a sprained back.
