The fatality occurred on August 17 when 57 year-old Sabo was pinned against a continuous miner.

The McElroy crew had mined a crosscut through (from no. 5 to no. 6 entry) when the miner operator warned the victim the rib was working. The victim withdrew approximately three feet outby the right side rib protector shield, toward the rear of the continuous mining machine, when the rib rolled and pinned him against the machine.

The rock and coal rib that fell measured approximately 20 feet (6.09m) long by five feet (1.5m) high and up to 10 inches (25cm) thick.

MSHA have advised operators to examine the roof and ribs frequently while working; take down or adequately support any loose ribs or roof before working or traveling in the affected area; stay aware of changing roof and rib conditions and position yourself in a safe location; and remain within the confines of any protective device such as cabs, canopies and rib protectors as much as possible.
