A damaged chemical tank in Southern California, containing methyl methacrylate, cracked over the weekend, raising hopes among authorities that the pressure relief could avert a catastrophic explosion, though residents remain evacuated and a class-action lawsuit has been filed.
Southern California authorities are closely monitoring a damaged chemical tank in Garden Grove that cracked over the weekend, containing 6,000-7,000 gallons of methyl methacrylate, a chemical used in plastics. The crack has sparked cautious optimism among fire officials, who believe it might be relieving internal pressure, thus reducing the risk of a catastrophic explosion. An "all-night mission" is underway to confirm pressure relief, as the tank's interior temperature reached 100°F (37.7°C), increasing the chemical's conversion to gas and raising pressure. Firefighters are continuously spraying water to cool the tank and using drones for temperature surveillance. Officials confirmed only one crack and no active chemical leak, with atmospheric monitoring showing no chemicals escaping. Governor Gavin Newsom declared a state of emergency, and containment barriers are installed to prevent environmental contamination. Residents in the evacuation zone face displacement and potential health risks from methyl methacrylate exposure, which can cause respiratory and neurological problems. A class-action lawsuit has been filed against GKN Aerospace Transparency Systems, the facility operator, over potential property value impacts. GKN Aerospace has apologized and is working to mitigate risks, despite a history of regulatory violations.
