Over 40K Evacuated Over Chemical Tank in California
Officials said the overheated tank could rupture or explode, and about 40,000 residents were ordered out as crews worked to cool it.
- On Thursday, May 21, 2026, a methyl methacrylate leak at GKN Aerospace in Garden Grove prompted emergency officials to evacuate approximately 40,000 residents after the chemical overheated within a storage tank, creating risks of catastrophic spill or explosion.
- Broken, "gummed up" valves prevented crews from draining the tank, forcing Orange County Fire Authority Incident Commander Craig Covey to implement emergency cooling measures while bracing for rupture or thermal-runaway explosion.
- Fire Authority Division Chief Craig Covey reported Saturday that internal tank temperatures climbed to 90°F, while Orange County Health Officer Dr. Regina Chinsio-Kwong warned inhaling vapors from the 7,000 gallons can cause severe respiratory distress.
- California Governor Gavin Newsom declared a state of emergency on Saturday to mobilize state resources and expand shelter availability as officials confirmed schools and facilities remain closed with no timeline for residents to return.
- Working 24 hours a day, emergency crews continue stabilizing the facility using containment barriers and thermal-monitoring drones while officials maintain the large exclusion zone to ensure community safety during the ongoing crisis.
