METAL/NONMETAL MINE FATALITY - On February 3, 1999, a 39-year-old shipping operator with 1 year and 7 months mining experience was fatally injured at a titanium mill. The victim had deenergized the feed conveyor and climbed over the head pulley to gain access to the main discharge chute for the purpose of removing residue material. A mechanical sampler arm that cycled automatically every 5 minutes had not been deenergized and blocked against motion. When the sampler arm cycled, he was crushed against the chute wall.
Maintenance should not be performed unless the power is off and machinery components are blocked against hazardous motion.
