A storage tank containing 6,000 to 7,000 gallons of methyl methacrylate overheated and began venting vapors at an aerospace plastics facility in Garden Grove. Authorities warned the tank could fail and crack, releasing chemical onto the ground, or could explode. Evacuation orders affected about 40,000 people across Garden Grove and parts of five nearby Orange County cities after crews were unable to stop the leak overnight. No injuries or deaths were reported. Officials later said they maintained the tank’s temperature, which bought time to determine how to fix the problem. The facility is near Disneyland, though the theme parks were not under evacuation orders.
"A storage tank holding between 6,000 and 7,000 gallons (22,700 and 26,500 liters) of methyl methacrylate overheated Thursday and began venting vapors into the air at an aerospace plastics facility in Garden Grove, a city in Orange County, the local fire authority said."
"The tank could fail and crack, releasing the chemical onto the ground, or it could explode, Orange County Fire Authority Division Chief Craig Covey said Friday. "This thing is going to fail, and we don't know when," Covey said. "We're doing our best to figure out when or how we can prevent it.""
"Officials ordered residents in Garden Grove to leave and expanded evacuation orders Friday to some residents of five other Orange County cities - Cypress, Stanton, Anaheim, Buena Park and Westminster - after being unable to stop the leak overnight on the tank at GKN Aerospace, which makes parts for commercial and military aircraft."
"In an update later Friday, Covey said authorities have been able to maintain the tank's temperature, buying time to figure out how to fix it. No injuries or deaths have been reported, authorities said."
