CSB Says Yenkin-Majestic Has Not Addressed Five Columbus Plant Safety Recommendations
The U.S. Chemical Safety and Hazard Investigation Board says Yenkin-Majestic/OPC Polymers has not substantively responded to or implemented five recommendations following a fatal 2021 explosion at its Columbus, Ohio plant. The company’s reported September 2026 federal guilty plea and unresolved safety findings are relevant to supplier and contractor risk reviews, but the update identifies no new procurement action or requirement.
