EXPLODING VESSELS UNDER PRESSURE · NO DYS AWY FRM WRK,NO RSTR ACT
Employee was using CO2 to dislodge a chunk of material in the preheater tower. When the shot went off, it dislodged a small port door, which contacted the employee's left elbow. This caused a small laceration.
MACHINERY · DAYS AWAY FROM WORK ONLY
EE on Preheat Tower found a water gun disconnected from its hose with the water valve closed. A miner asked on the radio if the "pressure was good" and they heard someone say "yes". When EE began to screw the hose coupling onto the gun, the other miner opened the water valve. High pressure water then shot out of the coupling and was injected with a piece of cloth into EE's hand.

MSHA Violations (issue date), Accidents (accident date), and Inspections (begin date). Snapshot 2026-10-17.
Counts describe published rows, including contractor records; accident records are not distinct incidents or numbers of people injured.
Zero means no matching records in the imported sources, not proof of no events. Historical coverage differs by source; absence before a source begins reporting is not a zero incident rate. Invalid or absent dates and records after the snapshot are excluded.
S&S means SIG_SUB=Y. Fatality records use DEGREE_INJURY_CD=01. Proposed penalties are not final assessed or paid amounts; missing dollar values are omitted.
Inspection hours are SUM_TOTAL_ON_SITE_HOURS attributed to the inspection start date, without supervisor/trainee hours. Missing hours are omitted; a started inspection may still be open.
Portfolio totals use current mine membership, including events before the current owner or operator's tenure.
CFR headings link to the current Title 30 index; they are not historical legal determinations.
