Orange County Health Officials Revise Statement on Chemical Tank Crisis, Confirm Vapor Release
Orange County health officials have revised their previous statement regarding a chemical tank crisis at a Garden Grove aerospace company, acknowledging that vapors were indeed released. Initially, Health Officer Dr. Regina Chinsio-Kwong stated there was no contamination or vapor release. However, this was contradicted by the Orange County Fire Authority, which reported a vapor release from a pressurized tank containing methyl methacrylate (MMA), a chemical used in manufacturing. The incident led to the evacuation of approximately 300 employees and a subsequent evacuation order affecting 50,000 residents. Air monitoring began on May 22, and officials have since confirmed that air quality readings remained within normal ranges, indicating no significant health risk from MMA exposure. The California Department of Public Health has stated that the health and safety risk has been eliminated.
