Data aggregated from public federal enforcement records (OSHA, WHD, MSHA, EPA, FMCSA, NLRB, OFLC, BLS). Employer profiles matched by name and location — matching errors may occur. Risk scores computed by FastDOL, not official government assessments. OSHA citations typically appear 3-8 months after the inspection, so very recent enforcement actions may not yet be reflected.
