Orange County Evacuations Continue as Overheated Chemical Tank Spurs Explosion Fears

A methyl methacrylate storage tank at GKN Aerospace in Garden Grove overheated, triggering an evacuation of about 50,000 residents. Fire officials are cooling the tank and monitoring for leaks or a possible explosion; authorities say a low-volume release is most likely, but the risk of a blast remains. No injuries have been reported, air monitoring around the evacuation zone is within normal limits, and a class-action lawsuit has been filed. California has declared a state of emergency as investigators and hazmat crews work to stabilize the site and prevent spills into waterways.
