Mining, Quarrying, and Oil and Gas Extraction, Workplace Safety Record
428 companies · 1,469 violations · 1,463 inspections
OSHA's enforcement file documents 1,469 citations across 428 mining, quarrying, and oil and gas extraction companies, averaging 1.00 violations per inspection with a 61% serious-or-willful citation share.
Mining, Quarrying, and Oil and Gas Extraction (NAICS 21) — mining, oil and gas extraction. Federal MSHA (not OSHA) oversees most mining operations, so OSHA enforcement records here reflect only the surface and support operations under federal OSHA jurisdiction: 428 the United States employers, 1,463 inspections, 1,469 violations.
Industry-wide statistics: 1.00 violations per inspection on average, with average final penalty of $15,258 per inspection. The largest single employer by violation count is Patterson-Uti Drilling Company LLC. For workers evaluating job offers in this sector, the violation rate is a useful sector-wide signal — but the per-company pages give the specific safety record for individual employers, which is what actually matters for an individual employment decision.

Mining, Quarrying, and Oil and Gas Extraction Hazard Profile
Mining and oil-and-gas extraction operate under a distinct enforcement framework. The Mine Safety and Health Administration (MSHA) covers most mining work, while OSHA covers surface oil-and-gas operations. Confined-space entry, hot-work permits, and process-safety management standards dominate citations in this sector.
Mining, Quarrying, and Oil and Gas Extraction runs a relatively low citation density at 1.00 violations per inspection, indicating that most inspections in this sector close with a small number of citations. Low density usually reflects either lower inherent hazard exposure or a workforce where employer safety programs are mature and well-documented.
The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) publishes the controlling standards, and the Enforcement Results Data files are the primary public source for citation history.
Severity and Penalty Patterns
Serious and willful citations account for 61% of all citations — well above the federal average. A high serious-or-willful share is the clearest signal that citation counts in this sector reflect substantive hazard exposure rather than paperwork or recordkeeping issues.
Final penalties in mining, quarrying, and oil and gas extraction average $15,258 per inspection. Final penalty figures reflect amounts after settlement, not the proposed amounts initially issued in the citation. OSHA regional offices have discretion to settle citations through informal conferences in exchange for verifiable abatement plans.
Industry-level injury benchmarks come from the U.S. Bureau of Labor Statistics' Survey of Occupational Injuries and Illnesses, which publishes annual incidence rates by NAICS code. Reading citation counts alongside BLS injury rates is the cleanest way to interpret whether the citation pattern reflects underlying hazard exposure or elevated enforcement attention.
What This Means for Workers
Workers in mining, quarrying, and oil and gas extraction retain the full set of federal protections under the Occupational Safety and Health Act, including the right to a safe workplace, the right to know about hazards, the right to training in a language they understand, the right to copies of medical records and exposure monitoring results, and the right to refuse imminent-danger work without retaliation. Confidential complaints can be filed at osha.gov/workers/file-complaint or by calling 1-800-321-OSHA. The OSHA Workers' Rights page spells out the full set of protections under Section 11(c) of the OSH Act.
Methodology and Data Sources
Counts on this page come from OSHA's public Integrated Management Information System (IMIS) enforcement file, refreshed from the Department of Labor's Enforcement Results Data files. Industry classification follows the NAICS code recorded by OSHA at the time of inspection.
The Workplace Safety Score shown on linked company pages applies four weighted factors: violation rate versus industry, share of serious-or-willful citations, repeat-citation ratio, and average penalty per inspection. Each factor is normalized so that companies in inherently risky sectors are compared against their actual peers rather than against low-hazard work. Read the full methodology for the exact formula and edge cases.
