2003 to 2026. 2026 is year to date through November 4, 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. Errors in data processing or establishment grouping are possible. Penalty amounts are the latest on record and may differ from the initial assessment or the final amount after informal conference, settlement or judicial review. Company pages group records by employer name, city and state as OSHA reported them, not by legal entity (methodology). Found an error? Report it. This product uses the DOL Data API but is not endorsed or certified by the DOL. For official and authoritative records, visit osha.gov.

SafetyRecord also offers this data as an API and bulk files, with inspections grouped by establishment and a record of how citations change after OSHA publishes them: Data & API.
