Experts are trying to prevent a tank of hazardous chemicals from exploding in Southern California. The tank, which contains methyl methacrylate, a flammable chemical used in plastics and manufacturing, could rupture and spill up to 7,000 gallons of toxic material or explode and endanger other tanks on the GKN Aerospace site. Tens of thousands of people are covered by the evacuation orders.
NEW YORK: Experts trying to prevent a tank of hazardous chemicals from exploding in Southern California found a "potential crack" in the container that might be reducing the pressure, a fire official said on Sunday.
Since Friday, officials have warned that the tank, which contains methyl methacrylate, a flammable chemical used in plastics and manufacturing, could rupture and spill up to 7,000 gallons (26,500 litres) of toxic material or explode and endanger other tanks on the GKN Aerospace site. Evacuation orders were issued on Friday for an area in Garden Grove, a suburb roughly 30 miles (48km) south of Los Angeles. Tens of thousands of people are covered by the evacuation orders.
TJ McGovern, interim fire chief of the Orange County Fire Authority, said in a video message posted on social media that a team of specialists on Saturday night found "a potential crack in the tank, which could potentially be relieving some of the pressure in there.
" Discovering the potential crack was "positive intel", McGovern said. Authorities are still trying to determine whether the possible crack has relieved pressure in the tank, a spokesperson for the Orange County Fire Authority told Reuters. Lowering the pressure could help avert an explosion, he said. Although officials for now are focused on measuring pressure, the spokesperson said, the crack eventually could allow authorities to gradually drain the chemicals.
California governor Gavin Newsom on Sunday said he had requested that president Donald Trump issue a federal emergency declaration to support response operations. Newsom declared a state of emergency for Orange County on Saturday. At one point on Saturday, the tank’s internal temperature reached as high as 90 degrees Fahrenheit (32.2C), the fire authority said.
But EPA Administrator Lee Zeldin told CNN’s "State of the Union" programme on Sunday that local officials were working to stabilise the tank by keeping its temperature under 85 degrees Fahrenheit.
"I’m being told this morning that the most likely scenario is one of a low-volume release, where the local authorities are going to be able to monitor, neutralize and contain the threat," Zeldin told CNN. Crews were preparing for a possible spill by looking for ways to dike, dam and divert the liquid into a holding area at the commercial site, rather than allow it to reach storm drains, river channels or the ocean, the fire authority has previously said.
Health officials have said they were concerned that prolonged exposure to vapor from the chemical could cause severe respiratory problems. Air monitors deployed in Garden Grove were not detecting any chemicals or pollutants on Sunday, the EPA said. Sensors located around the tank itself have not picked up any chemical leaks in the air, the fire authority spokesperson said. The Orange County Fire Authority and the Garden Grove mayor’s office did not respond to requests for comment on Sunday.
The incident began on Thursday at the GKN Aerospace facility, which specializes in the manufacturing and testing of windows and canopies for commercial and military aircraft, according to its website
