February 2, 2026 WY · Metal/Non-Metal assistant mine foreman, assistant mine manager HANDTOOLS (NONPOWERED)

Asphalt Specialties Co., Inc. · Struck by flying object

The miner was working on removing a bearing from a motor mount assembly. A small pry bar was being used to remove the bearing. The pry bar was under load when the miner struck the shaft with a hammer. The pry bar released and struck the miner in right cheek near the nose. The impact caused a laceration which required stitches and CT scans.
