Chemical Tank Leak in Garden Grove Prompts Evacuations

A hazardous chemical leak at GKN Aerospace in Garden Grove, California, has led to the evacuation of approximately 40,000 residents across multiple cities. The incident began on Thursday afternoon when a storage tank containing between 6,000 and 7,000 gallons of methyl methacrylate—a volatile chemical used in plastics manufacturing—overheated and started releasing vapors.

Orange County Fire Authority Division Chief Craig Covey stated that the tank is at risk of either cracking and releasing the chemical onto the ground or exploding. "This thing is going to fail, and we don't know when," Covey said.

Evacuation orders were initially issued for Garden Grove and later expanded to parts of five neighboring cities: Cypress, Stanton, Anaheim, Buena Park, and Westminster. Authorities have managed to stabilize the tank's temperature, buying time to address the situation. No injuries have been reported.

Health officials warn that exposure to methyl methacrylate vapors can cause respiratory issues, eye irritation, nausea, and headaches. Crews have established containment barriers to prevent the chemical from contaminating local waterways.

The affected area includes a significant Vietnamese community, raising concerns about language barriers in emergency communications. Local officials are working to provide translated updates and support to ensure all residents are informed and safe.

Disneyland, located nearby, remains outside the evacuation zone and continues to operate as usual.
