A massive chemical tank at a Southern California aerospace plant is threatening to explode in what officials are calling an unprecedented industrial disaster. Evacuation orders were issued for 40,000 people in Orange County on Friday as emergency crews warn the situation is spiraling toward catastrophe. The 34,000-gallon tank containing highly volatile methyl methacrylate (MMA) cannot be secured and is threatening to 'spill or explode,' according to officials at the GKN Aerospace facility. 🎥 Reuters/ABC AFFILIATE KABC / ORANGE COUNTY FIRE AUTHORITY VIA X #california #news #chemicalleak
