A fire at a Lineage cold storage facility in Boyle Heights, California, involving toxic anhydrous ammonia, and an earlier explosion scare at an Orange County aerospace facility raised concerns about hazardous chemical risks. Residents and officials question regulatory oversight as both facilities had prior violations, and conflicting information about chemical leaks caused public distrust.

A chemical tank leak at an aerospace plant in Garden Grove, California, has prompted evacuation orders for 40,000 residents. The overheated tank, containing methyl methacrylate, risks explosion or spillage, with authorities working to contain the hazard.
