Data aggregated from public federal enforcement and program records (OSHA, WHD, MSHA, EPA, NLRB, FMCSA, OFLC, BLS, SAM.gov, CMS, USAspending, CPSC, NHTSA) plus the UVA Corporate Prosecution Registry. Employer profiles matched by name and location — matching errors may occur. Risk scores computed by FastDOL, not official government assessments.
