Firefighters in Southern California said Monday that an industrial chemical tank at an aerospace facility in Garden Grove is no longer at risk of exploding after a structural crack relieved internal pressure, marking a turning point in an emergency that forced large-scale evacuations across Orange County.
The tank, located at the GKN Aerospace facility, had been overheating since Thursday and involved methyl methacrylate, a highly flammable chemical used in aircraft manufacturing. The situation escalated rapidly as temperatures inside the tank rose above safe levels, prompting emergency declarations and evacuation orders affecting tens of thousands of residents, according to Reuters.
