BREAKING — GARDEN GROVE, CALIFORNIA | Firefighters have successfully eliminated the threat of a catastrophic explosion at a chemical tank in Orange County, officials confirmed Monday, ending a four-day emergency that forced the evacuation of roughly 50,000 residents.
The damaged tank at GKN Aerospace Transparency Systems cracked over the weekend, releasing pressure and reducing the risk of a catastrophic failure, Orange County Fire Authority division chief Craig Covey said. Overnight operations allowed crews to verify temperatures inside the tank were falling and that pressure had been safely released.
“The results of the overnight evaluation of the tank — that the temperature inside had dropped and that pressure had been released — was incredibly positive news,” Covey told reporters Monday morning.
The tank, which holds 6,000 to 7,000 gallons of methyl methacrylate, overheated on Thursday at the aerospace company’s facility in Garden Grove, a city of roughly 170,000 located about 40 miles south of downtown Los Angeles. As temperatures inside the tank rose, officials warned of a potential explosion that could devastate the surrounding neighborhood.
Firefighters spent days spraying the tank with water to cool the chemical, using drones to monitor temperatures at 10-minute intervals. Containment barriers were erected to prevent any spill from reaching storm drains, creeks, or the Pacific Ocean.
Despite the scale of the emergency, no injuries have been reported. Air quality monitoring throughout the evacuation zone showed pollution levels remained within normal limits, state and federal environmental officials said.
Residents filed a class-action federal lawsuit against GKN Aerospace over the weekend, arguing that property values in surrounding communities had been impacted regardless of the outcome. The company apologized and said it was “working around the clock to mitigate the risk of a leak.”
Disneyland, located in neighboring Anaheim, was not placed under evacuation orders. Park officials said they were monitoring the situation but that operations continued as normal.
Authorities have not yet announced when evacuated residents will be permitted to return to their homes.
