Complaint Inspection: This inspection record is categorized as a complaint inspection in the DOL OSHA enforcement data. OSHA can open complaint-driven inspections after receiving safety or health complaints from workers or their representatives.
Penalty amounts may differ from final amounts after settlement or judicial review. How to read these records
About these records
A company page groups inspections with the same normalized employer name, city and state; it is not a legal-entity identifier (how pages are grouped).
This page displays public OSHA enforcement data. Status text follows the DOL inspection record first and may include citation-level context when the inspection feed and citation records are out of sync. Penalty amounts shown reflect the latest penalty amounts on record in the DOL database and may differ from initial assessments or final amounts. This is not an official OSHA resource.
OSHA's public enforcement data does not publish a "guilty" or "not guilty" field for inspections. The closest outcome fields available are the citation counts, penalty amounts, contest dates, final-order dates, and the inspection close date shown on this page. How to interpret these status fields. How initial and current penalties are recorded.
