A failed cooling system may have triggered the dangerous chemical leak at a Garden Grove aerospace facility that led officials to evacuate roughly 50,000 residents over an explosion threat, officials said. Orange County Fire Authority Chief TJ McGovern said that a pressurized storage tank holding 7,000 gallons of methyl methacrylate, a highly flammable liquid used in plastic manufacturing, began heating up after the cooling mechanism stopped working for reasons that have yet to be determined. “We don’t know why, but it stopped cooling,” McGovern told The Los Angeles Times on Tuesday.
