A “catastrophic” explosion at a chemical tank in Garden Grove has been averted, though some risks remain. The tank, containing methyl methacrylate, overheated due to a malfunctioning refrigeration system valve, prompting tense efforts by responders. While the most severe BLEVE risk has been mitigated, officials continue to address a fire concern and potential spill, keeping approximately 16,000 residents under evacuation orders. No injuries or contamination have been reported, and ongoing efforts focus on further cooling the tank and preventing any leaks.
