Your rights
If you worked at this site, the inspection file is a public record once the case closes; request it from the Cal/OSHA district office with activity number 343741732. A worker who reported the hazard, the injury or the inspection and was then fired, demoted or cut has a retaliation claim under Labor Code 6310, one year to file with the Labor Commissioner and longer to sue. Injuries themselves go through workers' compensation. Free, confidential review: (800) 371-3088.

About this data: Records come from the U.S. Department of Labor's OSHA enforcement datasets (inspection, violation, accident and accident injury tables), which carry Cal/OSHA's state-plan inspections alongside federal ones. We load every inspection of a California worksite opened since January 1, 2000 and refresh it weekly. Employer names, addresses and industry codes are as the inspecting office recorded them; similar names are grouped where they clearly refer to the same employer. A citation can be reduced, vacated or withdrawn on appeal, and an inspection can stay open for months, so a record can change. Penalties shown as "current" reflect the latest status in the federal file. This page is public information about the employer's regulatory record, not legal advice and not a statement that any person was harmed or any law broken beyond what the record states.
