PORTABLE CRUSHER #25Metal/Nonmetal

While working on the cone crusher top assembly, employee A was holding bolt with wrench. Employee B was loosening nut with an impact wrench; when torque was applied to the nut employee A lost grip on wrench causing wrench to make contact with employee B's face resulting in damage to mouth requiring five external stitches and 2 internal stitches.

While working near the jaw crusher a rock fell and hit the miner a glancing blow to the left shoulder. The primary contributing factor was the miners location - too close to the jaw. After a trip to the clinic on his way home, it was determined that the only damage was bruising. The miner returned to work the next day to regular duty. There was no time loss, but he saw a doctor.
