    Safety sources and definitions

    MSHA Violations (issue date), Accidents (accident date), and Inspections (begin date). Snapshot 2026-10-13.

    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.
