2003 to 2026. 2026 is year to date through October 14, 2026. OSHA inspection records before 2003 rarely carry a NAICS code, so an inspection from those years appears here only when its establishment record carries a NAICS code.

About these figures

Source: U.S. Department of Labor OSHA enforcement data. Industry is the NAICS code on its establishment record, taken from its inspection records. Standard pages count by the NAICS code on each inspection instead, so their industry figures can differ from this page.
Citations are violation items as DOL records them, deleted items excluded. Citations also include unclassified items and items with no type recorded. Current penalties are amounts after any reductions.
Having OSHA inspection records is common for businesses in regulated industries.

Data Source and Methodology

DOL source data

Data on this page comes from the U.S. Department of Labor's OSHA enforcement database, accessed via the DOL public data API. Records are refreshed from published DOL data. We strive for accuracy, but errors in data processing or establishment grouping are possible. Penalty amounts reflect the latest penalty amounts on record in the DOL database and may differ from initial assessments or final amounts after informal conference, settlement, or judicial review. Company pages group inspection records by normalized employer name, city, and state as reported in OSHA records. That grouping is deterministic and non-fuzzy, but it is not a universal legal-entity identifier. If you believe any record is inaccurate, please report it and we will investigate. This product uses the DOL Data API but is not endorsed or certified by the DOL. For official and authoritative records, visit osha.gov.
