Garden Grove, Calif. Emergency crews with the Orange County Fire Authority conducted nighttime visualization and monitoring operations after a chemical storage tank at the GKN Aerospace Transparency Systems plant overheated on Friday; teams discovered a single crack over the weekend and assessed pressure and temperature changes on Sunday and Monday to avert an explosion. Officials said Monday that the crack relieved enough pressure and that tank temperatures fell, eliminating the immediate risk of a boiling-liquid expanding vapor explosion; authorities lifted evacuation orders for some residents, noted no hazardous chemical detections, reported the tank held roughly 6,000–7,000 gallons of methyl methacrylate, and said monitoring and inspections would continue.
