The Garden Grove Chemical Release

On Thursday, May 21, 2026, a storage tank at the GKN Aerospace facility on Western Avenue in Garden Grove, near the Cypress border, overheated and began releasing methyl methacrylate vapor into the surrounding air. Orange County Fire Authority crews responded and continue to work to stabilize the tank.

Evacuation orders have been issued, lifted, and reissued more than once as conditions changed. As of May 24, 2026, the evacuation zone covers roughly 50,000 residents across portions of Garden Grove, West Anaheim, Cypress, Buena Park, and Stanton. Thirteen school campuses were closed, and evacuation centers have been opened at Stanton City Hall, the Garden Grove Sports & Recreation Center, the Cypress Recreation Center, Freedom Hall in Fountain Valley, Oceanview High School in Huntington Beach, and Los Amigos High School in Fountain Valley.

On May 24, 2026, Governor Newsom submitted a request to the White House for a federal emergency declaration in response to the release.

If you live, work, or send your children to school in any of these communities, this release may have a direct effect on you and your family.

Health Effects

What Methyl Methacrylate Exposure Can Do

Methyl methacrylate (MMA) is a volatile chemical with a strong, sharp odor. Short-term exposure to MMA vapor is known to cause a range of symptoms.

●Eye, nose & throat irritation ●Coughing & shortness of breath ●Headache ●Dizziness ●Nausea ●Skin & eye irritation

People with asthma or other respiratory conditions, young children, older adults, and pregnant residents can be more sensitive to these effects. If you or a family member experienced symptoms during or after the release, document them and seek medical attention. A medical record created close in time to the exposure matters.
