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.
OSHA may publish multiple citation rows in the same inspection with the same standard and penalty fields. Separate rows can still differ in OSHA metadata such as citation identifier, recorded instance count, exposed workers, or gravity value. Contest and Final Order columns show citation-level dates from OSHA's enforcement record. A dash means OSHA's record does not currently show that activity for the citation.
Source: OSHA chemical exposure sampling data (OSHA Information System). P = Personal (worker breathing zone), A = Area (general air). Rows marked QC are analytical quality control measurements, not chemical exposures. OSHA PEL (Permissible Exposure Limit) values from the OSHA Occupational Chemical Database, matched via IMIS substance code (analyte code) (exact government key).
Understanding These Penalties
The maximum penalty for a serious violation in 2025 is $16,550 per violation. For willful violations, the range is $11,823 to $165,514. The current penalty column shows the latest amount on record in OSHA's database for each citation. When the current penalty differs from the initial penalty, OSHA's records show that the amount changed during the enforcement process, but this page does not determine the specific reason for each change. Penalty amounts are set by OSHA and adjusted annually for inflation.
18 inspections, 1989 to 2025. Each row is one inspection; point at or tap a row for its dates and totals.
Source: DOL OSHA enforcement data (inspections and violations), linked via activity_nr (exact government key).
Penalty changes: Amounts shown reflect what OSHA's enforcement record publishes. The reason for any change is not stated unless OSHA's record explicitly says so.
Short cases: When a case closed soon after it opened, the closed marker is drawn slightly to the right so both markers stay visible. Each row's card shows the exact dates.
