A damaged chemical tank in Southern California is suspected to have developed a crack, potentially reducing the chances of a catastrophic explosion. However, an evacuation order for approximately 50,000 local residents remains in place with no specific timetable for their return, according to a statement by a fire official on Sunday.
Orange County Fire Authority Captain Wayhowe Huang mentioned that experts are currently assessing the tank following the identification of a potential crack overnight. Huang noted that as of Sunday morning, there is no evidence of any leakage of the highly volatile chemicals stored in the tank.
“While the risk of a potential explosion persists, we are not ruling it out,” Huang emphasized. “Our operations continue under the assumption that this risk is still present.”
Firefighters have been actively spraying water on the exterior of the tank to cool down the chemicals inside, aiming to avert any potential explosion.
Lee Zeldin, the head of the U.S. Environmental Protection Agency, indicated on Sunday that the most likely outcome at present is a low-volume release, allowing officials to monitor, neutralize, and contain any potential threat.
Efforts are focused on keeping the tank’s temperature under control, as emphasized by Craig Covey, the Orange County Fire Authority division chief. Covey suggested that the suspected crack might actually be relieving some internal pressure, potentially altering the situation’s course and response strategy.
The pressurized tank initially overheated on Thursday, leading to the venting of vapors at a Garden Grove company site. No injuries have been reported, and air quality tests within the evacuation zone have shown no abnormal pollution levels. Specialized equipment has been deployed to prevent any gas release from the compromised tank.
Authorities are working to mitigate the situation by cooling the chemicals inside the tank to prevent leaks or explosions. In case cooling efforts fail, the priority would be to contain any potential leak rather than risk a widespread explosion.
Residents in the affected area have taken legal action against GKN Aerospace Transparency Systems, the company operating the facility housing the damaged tank, expressing concerns about property values and potential health risks. The company has expressed its focus on safety and cooperation with emergency services and authorities amid the ongoing situation.
The damaged tank, situated at GKN Aerospace, holds a significant amount of methyl methacrylate, a chemical used in plastic production. Exposure to this chemical can lead to severe health issues, although Orange County health officials have reassured residents that its distinct odor would likely provide an early warning without immediate harm.
