FBI seizing evidence at California plant where chemical tank overheated and forced evacuations

The FBI executed a search warrant at a Southern California aerospace facility following a chemical tank overheat last month. This incident forced 50,000 residents to evacuate due to explosion fears. A federal judge approved the seizure of documents and records specifically related to the storage, use, or disposal of methyl methacrylate, the chemical contained within the affected tank. Federal authorities served the warrant on Wednesday to collect evidence regarding the facility's handling of the substance.
