Aerospace firm GKN Aerospace is facing a new lawsuit linked to a chemical incident that compelled many Californians to evacuate over Memorial Day weekend. The legal action claims that the UK-based company exhibited negligence and failed to uphold safety protocols, despite previous regulatory warnings and a track record of environmental infractions.
This lawsuit is one of many that arose following a malfunctioning storage tank containing flammable methyl methacrylate, which overheated and broke down, leading to evacuation mandates in various Orange County cities during the holiday.
At that time, officials reported that the tank unexpectedly cracked, releasing pressure. Luckily, this prevented a major explosion and allowed many evacuees to return home safely.
The lawsuit’s claim of “trespass” is particularly interesting. It suggests that chemical vapors and odors entering the community amounted to an invasion of residents’ properties. Claimants are seeking unspecified damages for emotional distress, temporary loss of use of their homes, and potential long-term decreases in property values caused by the chemical exposure.
During the state of emergency, around 50,000 residents in areas including Anaheim, Buena Park, Cypress, Garden Grove, Stanton, and Westminster were ordered to leave their homes.
President Trump declared a federal emergency in light of these events. The complaint pointed out that GKN failed to implement adequate safety measures despite understanding the risks associated with methyl methacrylate operations.
The Garden Grove facility, which has been operational since 1966, is known for manufacturing window and canopy structures for both commercial and military aircraft, along with spacecraft. According to court documents, it has a history of environmental regulation issues, including notable fines related to air quality violations in 2025.
The complaint emphasizes that this history suggests the company should have adhered to stricter safety standards and monitoring practices due to the nature of their hazardous materials work.
Exposure to methyl methacrylate is reported by the Environmental Protection Agency to potentially cause severe respiratory illnesses, neurological issues, as well as skin, eye, and throat irritations.
Currently, more than 40 lawsuits have been filed related to this incident. Fox News Digital has reached out to GKN for a response and company representatives apologized for the situation earlier this week.
GKN senior vice president Steve Carlin acknowledged the difficulty of the situation, particularly during the holiday, stating the company is dedicated to understanding what occurred and finding ways to assist those affected.
