Chemical Leak at Garden Grove Aerospace Facility Prompts Evacuations

A hazardous chemical leak at an aerospace facility in Garden Grove, California, has led to the evacuation of approximately 40,000 residents across multiple Orange County cities. The incident began on Thursday afternoon when a 34,000-gallon storage tank at GKN Aerospace, located in the 12000 block of Western Avenue, started leaking methyl methacrylate—a volatile, flammable chemical used in plastic manufacturing.

Emergency crews responded promptly, establishing an initial evacuation perimeter encompassing parts of Garden Grove, Cypress, Stanton, Anaheim, Buena Park, and Westminster. Despite efforts to stabilize the situation, including cooling the tank with water, the leak persisted into Friday, raising concerns about a potential rupture or explosion.

Garden Grove Fire Chief Craig Covey emphasized the gravity of the situation, stating, "This is not precautionary. ... This thing is going to fail, and we don't know when." He further explained that the tank could either crack, releasing the chemical onto the ground, or explode.

Evacuation orders were expanded on Friday morning to include additional areas, with residents directed to leave immediately. Evacuation centers were established at the Garden Grove Sports & Recreation Center and the Cypress Community Center to assist displaced individuals.

As of Friday evening, no injuries had been reported. Authorities continue to monitor the situation closely, urging residents to adhere to evacuation orders and stay informed through official channels.
