How to read this record
Each row is one inspection by Cal/OSHA (or, rarely, federal OSHA) of one worksite. Why is the reason it was opened. Penalty is the current figure after any appeal or settlement; where it was reduced, the amount the inspector first proposed is shown under it. "Serious" means a realistic possibility of death or serious harm; "willful" and "repeat" carry penalties up to $162,851 each.
Citations document that the employer was told, in writing, what the rule required and when. That knowledge is often the center of a retaliation case: a worker who complained about the hazard an inspector later cited, and was then fired or cut, has a Labor Code 6310 claim, with lost wages and attorney's fees.

If you work, or worked, at 3m Company
Write down what you reported, to whom and when, and what changed afterward: shifts, pay, duties, write-ups. Request the inspection file from the Cal/OSHA district office using the activity number on the inspection page. An injury goes through workers' compensation; a firing, demotion or threat after a safety complaint or injury report is an employment claim with a one-year deadline at the Labor Commissioner (Labor Code 6310) and a longer one in court.

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 A citation can be reduced, vacated or withdrawn on appeal, and an inspection can stay open for months, so a record can change.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.
