GARDEN GROVE (CNS) – Orange County fire authorities were “bringing people in from all over the country” Saturday to confront a rising threat from a compromised chemical storage tank that authorities said is either going to crack open and leak thousands of gallons of toxic materials or explode.
Tens of thousands of people remained under evacuation orders in Garden Grove and surrounding areas Saturday, while a dangerous overnight foray into one of the tanks at GKN Aerospace revealed that temperatures there were rising by about 1 degree per hour and not decreasing as hoped, according to the Orange County Fire Authority.
Unified Incident Commander Craig Covey said Saturday that working with the chemists from the manufacturer’s emergency response team, the OCFA put its people “back in harm’s way last night” transitioning from defense to offense in an attempt to neutralize an additional 15,000-gallon tank to remove its explosive potential in the event that an adjacent tank blows up.
He said the workers were able to see a gauge that’s covered by water, and it revealed that the temperature had increased to 90 degrees from 77 degrees Friday morning.
The team was currently allowing the tank to “cure at a slower rate and reducing its (building) overpressure,” Covey said.
Additionally, the OCFA is “bringing people in from all over the country … talking to people all over the place, trying to come up with additional options,” he added. “Letting this thing just fail and blow up is unacceptable to us.”
He added that “very aggressive” contingency plans are being employed in case the tank blows up or leaks, including fire and medical emergency plans, though the only people currently at risk are the firefighters and police officers on scene, Covey added.
If the tank leaks, authorities are trying to establish “some diking and damming and divert it to a spot that could be holding area” to prevent the fluid from “getting into our storm drains, our river channels and ultimately into the ocean, (causing) an environmental disaster,” Covey said.
California Gov. Gavin Newsom proclaimed a state of emergency Saturday.
The proclamation directs the California Governor’s Office of Emergency Services and all state government agencies to support Orange County and impacted local jurisdictions to address the emergency. It also unlocks additional emergency response resources and authorities, including making state- owned properties and fairgrounds available to provide shelter for evacuated residents as necessary.
“@Cal_OES has been mobilized for over 24 hours and state agencies are supporting impacted communities to protect public safety, and assist local officials as response efforts continue,” Newsom said Saturday.
Rep. Derek Tran, D-Cypress, said he was urging Newsom to submit a request to President Donald Trump for a federal disaster declaration “in preparation for a potential catastrophic incident.”
The situation developed shortly after 3 p.m. Thursday at the facility at 12122 Western Ave., due to a chemical that became overheated inside a large tank. OCFA crews and Garden Grove police initially responded around 3:30 p.m. to GKN Aerospace because the overheated 34,000-gallon tank had begun venting vapors and triggering a sprinkler system designed to spray water on the tank to cool the material inside. The tank is located in proximity to two other storage tanks.
The chemical in the tank is methyl methacrylate, a toxic and highly flammable liquid chemical used in the manufacture of acrylic plastics. GKN Aerospace, a leading global supplier of vehicle and aircraft components, manufactures acrylic plastics.
GKN Aerospace posted the following statement on its website Saturday:
“There is a serious and evolving situation regarding a thermal issue in a chemical storage tank at our Garden Grove site in California. The situation remains ongoing and we are fully focused on working with emergency services, specialized hazardous material teams and the relevant authorities to ensure the safety of the local community, our employees and everyone else involved. We sincerely apologize for the significant disruption to the many local residents and businesses who have had to be evacuated. We are working tirelessly with all relevant experts to resolve this situation as safely as possible and in a timely manner and are deeply grateful for the continued skill and dedication of the Orange County emergency services.”
Evacuation orders were issued, but were lifted Thursday night when crews believed they were making progress mitigating the situation. But Friday morning, the orders were re-instituted “due to changing conditions,” according to the OCFA. As the morning wore on, the situation worsened, and the evacuation zone was expanded to create a roughly one-mile buffer area around the tank.
The overall evacuation zone in effect Saturday was north of Trask Avenue, south of Ball Road, east of Valley View Street and west of Dale Street.
Mayor David Shawver said the entire city of Stanton was in the mandatory evacuation zone, and urged everyone in the city to leave, with an emergency shelter located at Ocean View High School at 17071 Gothard St. in Huntington Beach.
Areas of Westminster and Anaheim were also affected by the evacuation order.
Santa Ana City Manager Alvaro Nunez said the city was not in danger, but officials there coordinating with the Santa Ana Police Department, OCFA, Santa Ana Unified School District and regional emergency response agencies, and “are ready to activate the Santa Ana Emergency Operations Center if needed.”
Officials clarified Saturday that the evacuation area was divided into a handful of zones, including three circular “blast zones” closest to the plant, with likely severe, moderate and light damage in the event of an explosion.
Beyond that, three other zones were identified: Areas of flammability where fire or flash fire could occur, areas that were “immediately dangerous to life and health, where it would cause injury if anybody inhales or is impacted by the product in question,” according to Nick Freeman, division chief with the OCFA, and a large “non-hazardous zone” where people could still smell odors from a leak.
After the first reports of a problem Thursday, firefighters began spraying the failing tank with water in an effort to cool the material inside.
Around midday Friday, Covey gave a bleak update online, saying authorities determined “The tank that is in the biggest crisis is in fact unable to be secured and mitigated.”
“There are literally two options left remaining,” 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.
No injuries have been reported as of Saturday morning.
It was unclear what caused the material in the tank to overheat.
Covey said a spill of the chemical is actually the “best case scenario, believe it or not,” favorable to an explosion and possible plume of toxic material spreading over the area.
Garden Grove Mayor Stephanie Klopfenstein implored residents to follow the evacuation orders.
“We understand it is frightening people who are worried about their homes, their businesses, their pets and loved ones,” she said. “But this is a serious situation and now is not the time to wait.”
Orange County Health Officer Dr. Regina Chinsio-Kwong said the MMA chemical is “very toxic.” She said there is a scarcity of reports on the effects of exposure to methyl methacrylate. “It can cause significant irritation in the lungs, the nasal passages, and it can also cause nausea, it can also cause dizziness,” Chinsio-Kwong said.
Rep. Derek Tran, D-Westminster, issued a statement Friday saying he was “closely monitoring” the situation.
“My office is in close contact with local police, fire, and emergency response officials as they work to contain the hazardous materials, assess air quality, and ensure residents and first responders are safe,” he said. “I am in contact with federal disaster relief officials, including FEMA and the EPA, to urge them to provide any available federal assistance for Garden Grove. I encourage everyone in the affected area to follow guidance from local authorities and avoid the impacted zones until further guidance is issued.”
Beach Boulevard was closed from Garden Grove Boulevard to Orangewood Avenue and several off-ramps on the Garden Grove (22) Freeway including Beach Boulevard, Knott Avenue and Valley View Street.

— Savanna High School, 301 N. Gilbert St., Anaheim;
— Kennedy High School, 8281 Walker St., La Palma;
— Oceanview High School, 17071 Gothard St., Huntington Beach.
Stanton’s Shawver said Savanna and Kennedy high schools had limited available space, and Savanna High School was closed overnight.
A public information hotline was available with up-to-date information at 714-628-7085, and Garden Grove was operating an emergency hotline at 714- 741-5444.
The lingering threat disrupted some events in Orange County including plans to open 39 vote centers Saturday and a The Giving Farm food bank operated by the Community Action Partnership of Orange County. One vote center and three ballot drop boxes are closed and Friday’s scheduled food bank was canceled.
In addition, the Garden Grove Strawberry Festival at the Village Green in downtown Garden Grove, which opened Friday and continues through Memorial Day, has canceled its planned parade and community breakfast. The festival remains open.
Nearby attractions including Disneyland and Knott’s Berry Farm remain open, but officials said they were monitoring the situation.
The closed vote center is at the Garden Grove Sports and Recreation Center, 13641 Deodara Drive, which is being used as an emergency evacuation center until further notice.
Ballot drop boxes in the evacuation zone are also closed. They are located at:
— Stanton Branch Library, 7850 Katella Ave., Stanton,
— Korean Martyrs Catholic Center, 7655 Trask Ave., Westminster, and
— Chapman Sports Park, 11700 Knott Ave., Garden Grove.
The Garden Grove Unified School District has canceled classes until further notice at Barker, Bryant, Carver, Enders, Garden Park, Lawrence, Wakeham and Patton Elementary School; Bell and Alamitos Intermediate School, Pacifica and Rancho Alamitos High School and Skylark Preschool.
Los Alamitos Race Course in Cypress canceled Saturday night’s eight- race program “in solidarity with the state of emergency declared in Orange County,” the track announced.
Los Angeles Mayor Karen Bass said city officials were closely monitoring the crisis.
“The Los Angeles Fire Department has confirmed that Los Angeles is not affected and there is no risk to the city,” Bass said Saturday afternoon. “The LAFD remains in close contact with the Orange County Fire Authority and Cal OES and is sending a hazmat specialist who will serve as a subject matter expert. The LAFD is on standby, ready to offer any further assistance and resources should they be needed. All Angelenos should avoid the area.”
GKN Aerospace paid about $900,000 to settle multiple environmental violations in 2021, including failing to keep emission records and operating equipment without a permit, according to the OC Register, which cited the South Coast Air Quality Management District.
