A chemical emergency in Orange County has kept tens of thousands of residents away from their homes as crews monitor an overheated chemical tank at a GKN Aerospace facility in Garden Grove.
CNN reported that officials ordered evacuations after a tank containing methyl methacrylate began overheating, raising concerns that it could leak or explode. The chemical is used in manufacturing plastics and can pose health risks through fumes or direct exposure.
Fire officials said a crack found in the tank may be helping release pressure, which could reduce the chance of a larger explosion. Still, evacuation orders remained in place while emergency crews continued cooling the tank and checking air quality around the affected area.
California officials declared a state of emergency for Orange County as shelters opened for displaced residents. The company has said it is cooperating with emergency responders.
The situation has also led to legal action from residents who say the evacuation disrupted their homes, work, and daily lives.
