Massive Hazmat Emergency Near Disneyland Prompts Evacuations Across Orange County

A major industrial hazmat emergency is currently unfolding in Southern California just a few miles away from the Disneyland Resort, forcing tens of thousands of Orange County residents to evacuate their homes and businesses.

The incident initially began on Thursday, May 21st, at the GKN Aerospace facility located on Western Avenue in Garden Grove. Emergency crews responded to reports of an overheated 34,000-gallon storage tank containing methyl methacrylate—a highly flammable chemical commonly used to manufacture plastics, resins, and various aerospace components. While the tank is not at full capacity, authorities estimate that roughly 6,000 to 7,000 gallons of the volatile chemical remain trapped inside.

Despite around-the-clock efforts by fire crews to cool the exterior of the structure, malfunctioning valves and compromised systems have caused internal pressure and temperatures to rise to critical levels.

Orange County Fire Authority Division Chief Craig Covey gave a stark update during a news conference, explaining that the manufacturer’s technical representatives believe a catastrophic failure is inevitable. Officials are currently preparing for two possible outcomes: either the tank cracks and the chemical leaks safely onto the ground where hazmat teams can neutralize the vapors, or the built-up pressure causes the tank to rupture violently.

While initial, smaller evacuation orders were briefly lifted when conditions seemed to stabilize on Thursday, the situation rapidly deteriorated on Friday, May 22nd. This prompted officials to reissue and significantly expand the evacuation zone. The current orders now impact approximately 40,000 residents across several neighboring communities, including Garden Grove, Anaheim, Buena Park, Cypress, Stanton, and Westminster.

At its closest point, the established evacuation boundary sits roughly four miles away from the Disneyland Resort. Because the resort is outside of the active danger zone, Disneyland Park, Disney California Adventure, and the Downtown Disney District are not under evacuation orders and currently remain open. Disney has not issued an official statement regarding the situation, and it remains to be seen if shifting conditions will have any impact on weekend park operations.

Local health officials have warned the public that breathing in methyl methacrylate vapors can cause severe irritation to the eyes, skin, nose, and respiratory tract. Three official emergency shelters have been established for displaced residents at Savannah High School in Anaheim, the Garden Grove Sports & Recreation Center, and the Cypress Community Center.

California Governor Gavin Newsom has officially declared a state of emergency for Orange County to help clear the way for immediate state resources and funding. The declaration will allow state emergency management officials and hazmat specialists to work directly alongside local crews as they scramble to handle the volatile facility and secure the surrounding neighborhoods.
