The FastDOL Report

Weekly workplace compliance news. Free.

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. OSHA citations typically appear 3-8 months after the inspection, so very recent enforcement actions may not yet be reflected. Data provided as-is. Report a data error.
