Most cited CFR sections
All violations issued in the selected period. Counts combine subsections.
Employee was grinding on a cracked I-beam to prep for welding. EE was wearing a welding hood/face shield and safety glasses. Some grinding dust breached EE's PPE. EE used the available eye wash. A few hours later while at home EE was experiencing eye pain and went to the ER for evaluation. Was given Erythromycin Ointment and referred to a Eye Doctor for debridement.
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.
