Southwest Critical Materials LLC safety activity

Breakers for the Hoist House tripped due to electrical storm activity. Main line power to the hoisting conveyance was disrupted until the breakers could be reset. The breakers were reset and power was restored to the hoisting conveyance.

While performing pre shift hoisting conveyance checks, the lower limit switch showed a fault causing the checks to fail that part of the testing. The lower limit switch was stuck due to small buildup of concrete on it. The limit switch was cleaned allowing the checks to pass.

During innertube retrieval, side loading occurred while the helper attempted to free the stuffing box by pushing/pulling on it. When released, the stuffing box deflected slightly outside the perceived red zone and the 90� pump-down hose contacted the helper's right ankle, causing a fall and ankle sprain.

Auxiliary Cage in the main shaft conveyance taken out of automated use for unscheduled improvement/upgrades to provide corrective actions for a HP Near Miss incident. No injuries, damage to equipment, or entrapment were encountered. The work will focus on upgrades to the automation programming and interlocks.

Damage received to aluminum rail of the service cage as the cage was shipped underground to transport materials. Downtime occurred due to repairs needed on the aluminum rail.

After pulling the inner tube with the latch head, the helper walked to the tube rack. While placing the tube, weight shifted toward the latch head, causing EE to lose balance slightly. EE's right hand lowered, and EE's ring finger was caught under the latch head as it contacted the rack. EE was wearing impact gloves.

Service Cage Damage. Upper brattice door was damaged while transporting materials down the shaft causing the brattice doors to interfere with the use of the cage. The brattice doors were repaired and the cage was put back into operation later that day.
