Most cited CFR sections
All violations issued in the selected period. Counts combine subsections.
The drive pulleys on the conveyor had become built up with frozen material. The conveyor was started to make sure all of the frozen material had been removed. A large pry bar was left on the conveyor belt when it was started. EE saw it and reached in to grab it when it was grabbed by the drive pulley and smashed EE's hand against the side of the conveyor frame.
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.
