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. Proposed is the penalty the inspector assessed; penalty is the current figure after any appeal or settlement. "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 Sterigenics
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 A citation can be reduced, vacated or withdrawn on appeal, and an inspection can stay open for months, so a record can change.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.
