On Friday March 16, 2018, at approximately 11:50 a.m., Jason M. Williams, a 34 year-old outby mechanic with 16 years of mining experience was fatally injured while operating a personnel carrier on a mine haulage road. The vehicle struck the right coal rib and rolled onto its left side. Williams was partially ejected from the personnel carrier and became trapped between the canopy of the personnel carrier and the mine floor. This accident occurred because the mine operator did not assure that equipment operators maintain full control of the personnel carrier while it was in motion. In addition, mine management did not provide safety features to prevent persons in outby personnel carriers from being ejected.

1. The mine operator did not assure that equipment operators maintain full control of the equipment while it was in motion.

   Acción correctiva: The mine operator retrained all miners on its existing safe operating program for diesel powered equipment. For personnel carriers equipped with three or four gears, the mine operator removed the ability for those transmissions to shift into third or fourth gear, in order to reduce the maximum traveling speed of the carriers. For personnel carriers equipped with only two gears, the mine operator utilized a mechanism to reduce maximum speed

2. The mine operator did not provide safety features to prevent persons in outby personnel carriers from being ejected.
