California chemical tank has cracked, causing state of emergency, thousands to evacuate

A chemical tank at the GKN Aerospace facility in Garden Grove, California, has cracked, prompting a state of emergency and the evacuation of approximately 50,000 residents. The 7,000-gallon tank contains methyl methacrylate, a highly toxic and flammable chemical used in resin and plastic manufacturing. Emergency responders have been working since Thursday to manage the overheating tank, which poses a risk of leaking or exploding due to a dangerous chemical reaction inside. Firefighters discovered the crack late Saturday while assessing the tank’s condition. Officials believe the crack may be relieving some pressure inside the tank, potentially reducing the immediate risk of an explosion. However, the situation remains precarious, as methyl methacrylate can release energy rapidly when reacting, causing a sudden pressure buildup that could turn the container into an explosive hazard. Continuous efforts, including spraying water on the tank, are underway to cool it and prevent further deterioration. The incident recalls a similar event in the United Kingdom in 2009, where an explosion at a resin manufacturing plant involving methyl methacrylate caused significant damage but no fatalities. In Garden Grove, authorities remain cautious due to the chemical’s volatility and the potential for widespread harm if the tank ruptures. The evacuation order remains in place as emergency teams monitor the tank closely, emphasizing the importance of public safety and swift response in industrial chemical emergencies.
