An aerospace company at the center of a chemical emergency leading to mass evacuations in California faces legal action. The lawsuit accuses GKN Aerospace, based in the United Kingdom, of negligence, trespass, and nuisance, claiming failure to maintain proper safety protocols despite previous warnings and environmental infractions.
This legal move follows an incident involving an overheating storage tank filled with flammable methyl methacrylate. The malfunction led to evacuation orders in several Orange County cities over the Memorial Day weekend. A crack formed in the storage tank, relieving pressure and minimizing the risk of a catastrophic explosion, allowing most evacuees to return home safely.
State of Emergency and Evacuations
Governor Gavin Newsom declared a state of emergency in Orange County in response to the hazardous chemical situation in Garden Grove. Plaintiffs in the lawsuit argue that the spread of chemical vapors and airborne contaminants into their community constituted a trespass, causing a property invasion.
The plaintiffs seek unspecified compensation and punitive damages for emotional stress, temporary property use loss, and decreased property value due to chemical stigma. The emergency forced approximately 50,000 residents from Anaheim, Buena Park, Cypress, Garden Grove, Stanton, and Westminster to evacuate.
Company’s Regulatory History
The lawsuit highlights GKN’s previous regulatory issues concerning environmental and air quality violations. It notes a 2025 settlement that resulted in significant penalties for air quality infractions. The complaint suggests this history should have prompted the company to ensure strict compliance and rigorous safety measures.
Exposure to methyl methacrylate can lead to severe respiratory, neurological, and skin issues, according to the Environmental Protection Agency. The Orange County Register reports at least 44 lawsuits have been filed in relation to the incident.
GKN’s Garden Grove facility, operating since 1966, manufactures windows and canopies for both commercial and military aircraft and spacecraft. The lawsuit claims GKN ignored safety risks associated with their operations.
Company’s Response
GKN Aerospace issued an apology for the emergency. Steve Carlin, Senior Vice President overseeing the Garden Grove site, acknowledged the challenges faced during the Memorial Day holiday. He assured commitment to understanding the events and supporting those affected.
