Evacuation orders lifted in California chemical tank emergency after worst-case explosion risk eliminated | CNN

Officials lift evacuation orders for some California residents living near a damaged chemical tank

~34,000 of 50,000 evacuees near GKN Aerospace's Garden Grove plant can return home after a 7,000-gallon methyl methacrylate tank cooled to 93°F, removing the catastrophic explosion risk. GKN supplies cockpit components to major global OEMs from 32 sites; no reopening timeline is a concrete reminder of how thin the margin is in concentrated aerospace supply chains.
