FBI Investigates Chemical Tank Incident in Southern California

An aerial view captured a chemical tank at GKN Aerospace in Garden Grove, California, highlighting federal authorities serving a search warrant at the facility. This action followed an incident where a chemical tank overheated, leading to the evacuation of 50,000 residents due to fears of a potential explosion.

Details of the Federal Search Warrant

The search warrant, signed by a federal judge, authorized the seizure of documents related to the ‘storage, use, or disposal’ of methyl methacrylate, the chemical involved in the incident. Authorities also sought samples from any container suspected of holding this chemical.

Additionally, records on ‘any cooling equipment or other equipment used to control or regulate the temperature of methyl methacrylate’ were targeted for seizure. The FBI confirmed its agents conducted the search at the GKN Aerospace facility, with several federal agents and vehicles present.

GKN Aerospace’s Response and Community’s Reaction

GKN Aerospace, known for manufacturing cockpit windows and windshields, has shown cooperation with authorities. The overheated tank contained 6,000 to 7,000 gallons of highly flammable methyl methacrylate, used in various plastics and coatings.

Steve Carlin, representing GKN, addressed the community’s concerns at a meeting. He apologized for the disruption and highlighted the company’s intention to maintain transparency during the investigation.

Community leaders have suggested relocating the chemical tanks away from residential areas. However, Carlin emphasized that it is too early in the investigation to make decisions regarding future actions.

Potential Health Risks and Safety Measures

Methyl methacrylate poses health risks including respiratory problems and irritation. Cooling system failure resulted in the tank overheating to 100°F (37.7°C). The situation stabilized at 92°F (33.3°C) when crews used water spray and removed insulation to cool it. A crack relieved pressure and prevented a catastrophic explosion.

Evacuees returned home after authorities announced the tank remained stable without sprinkler intervention. The Orange County District Attorney’s Office also initiated a criminal investigation to preserve evidence.

Lawsuits and Federal Investigation

Federal lawsuits have been filed by around a dozen evacuees, including businesses, against GKN Aerospace, citing negligence. These cases highlight reports of strong odors, respiratory irritation, and dizziness experienced by residents.

Lawyers representing affected residents and businesses are encouraged by the FBI’s involvement, hoping it will lead to justice for those impacted. They express concern over the proximity of such chemical facilities to residential zones.

Orange County health officials have reassured that no contamination occurred, continuing to monitor air quality and drainage systems. The incident at GKN Aerospace preceded another hazardous chemical emergency in Longview, Washington, underscoring the importance of chemical safety on the West Coast.
