Authorities are calling the toxic chemical leak in Garden Grove a “crisis situation,” triggering evacuation orders for roughly 40,000 residents and school closures.
AIR7 video from overhead on Friday afternoon shows unmanned fire hoses and an automatic sprinkler system spraying water on the overheated tank, which is facing a potential catastrophic failure.
The tank at GKN Aerospace is carrying a highly toxic and flammable chemical used to make plastics. Now, fire crews say the tank is going to fail in one of two ways: either with a spill of thousands of gallons of toxic chemicals or an explosion. Authorities just don’t know when or how it will end.

“There are literally two options left remaining,” Orange County Fire Authority (OCFA) Division Chief Craig Covey said. “One, the tank fails and spills a total of about 6,000 to 7,000 gallons of very bad chemicals into the parking lot in that area, or two, the tank goes into a thermal runaway and blows up, affecting the tanks that are around them that have fuel or the chemicals in them as well.”
Covey stressed that “there is no active gas leak, no plume in the area,” but he warned residents to heed the evacuation warnings and remain out of the area due to the possible spill or explosion. Officials said air quality was being actively monitored in the area, and all readings were still within healthy limits.
