Final MSHA investigation
On September 15, 2016, Gregory R. Duff, Mechanic (age 60), was injured while working on a front end loader. Duff had completed his assigned tasks and was dismounting the machine when he fell. He impacted the ground with his head, neck, and shoulders and was unconscious for several minutes. He was transported to Renown Hospital in Reno, Nevada and placed on life support. Duff died as a result of his injuries on September 26, 2016. The accident occurred because management failed to ensure that policies and procedures on maintaining three points of contact while using ladders were followed.
Root causes
  1. The victim traveled down the ladder from the rear left fender of the loader without having both hands free.

    Corrective action: All miners were retrained in accessing ladders and steps. The operator implemented a safe procedure to raise and lower tools.

Findings from MSHA's final investigation report, which supersedes the preliminary narrative above.
