Explosion & Fire at ONEOK Plant in Mont Belvieu, TX
Yesterday, an explosion and fire occurred around 11:00 a.m. at the ONEOK MBC Maintenance Plant in Mont Belvieu, Texas, originating in the heating system of the MB-4 fractionator. Emergency crews quickly contained the fire, and three workers were treated for non-life-threatening injuries. All personnel were accounted for, and officials confirmed no danger to the community. The MB-4 unit has been shut down for repairs and investigation.
Events like this are serious reminder that safety can never be taken for granted — whether in an industrial plant, research lab, or classroom. Every facility that handles hazardous materials must ensure:
✅ Regular review and rehearsal of emergency response plans
✅ Ongoing training and PPE compliance
✅ Periodic engineering and process safety audits
✅ A safety culture where anyone can stop unsafe operations
At the Laboratory Safety Institute (LSI), we believe incidents like this underscore the importance of prevention through People, Policy, and Practice.
