The threat of a catastrophic explosion from a damaged chemical tank in Garden Grove, California, has been alleviated following a successful overnight inspection that confirmed a crack in the tank had relieved pressure and cooled the chemical inside. The Orange County Fire Authority reported a drop in temperature from 100°F (37.7°C) to 93°F (33.9°C), which was seen as positive news. However, evacuation orders for about 50,000 residents remain in effect as a precaution. The tank, located at GKN Aerospace Transparency Systems, contains 6,000 to 7,000 gallons of methyl methacrylate, a chemical critical for plastic production. Continuous efforts to cool the tank included firefighters spraying water and using drones to monitor temperatures. Meanwhile, a class-action lawsuit has been filed against GKN Aerospace by local residents concerned about property values. Governor Gavin Newsom declared a state of emergency to expedite federal support for the ongoing situation.
