Final MSHA investigation
On September 26, 2014, Mark G. Benoit, Mechanic, age 55, was killed while performing maintenance on a forklift in a mill building. Benoit was adjusting the directional solenoid on the transmission from the ground when the forklift began to move forward, pinning him between a wooden support pillar and the forklift’s Falling Object Protective Structure (FOPS). The accident occurred due to management’s failure to ensure that persons performed repairs and maintenance on a forklift with the power turned off and the equipment blocked against hazardous motion. The forklift’s engine was running when the operator left the seat and performed maintenance on the directional solenoid that controls the transmission. Additionally, the parking brake was not set and the wheels were not chocked to prevent movement. The victim was not effectively protected against hazardous motion.
Root causes
  1. The accident occurred due to management’s failure to ensure that persons performed repairs and maintenance on a forklift with the power turned off and the equipment blocked against hazardous motion. The unblocked forklift exposed the victim to hazards associated with the potential movement of the machine.

    Corrective action: Management developed safe work procedures for blocking mobile equipment against hazardous motion before persons perform maintenance. Miners were tasked trained to follow these new procedures.

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