Fire officials have issued urgent evacuation orders in Southern California as emergency teams work to contain a significant chemical tank situation that is, as described, “currently in crisis” and poses risks of leaking or exploding.
At an emergency news conference, Interim Chief TJ McGovern of the Orange County Fire Department reported that crews have been tirelessly engaged at GKN Aerospace, a facility involved in manufacturing products for both commercial and military aircraft. This effort followed the detection of a large tank releasing toxic gas.
Authorities confirmed on Thursday that methyl methacrylate (MMA), a volatile and flammable epoxy used in the aerospace sector, was leaking from a 34,000-gallon storage tank. Consequently, firefighters began implementing critical cooling measures.
Initially, officials believed they had the situation under control and thought residents might return home. However, by Friday morning, conditions had markedly deteriorated.
“It turned out that securing or mitigating the tank at greatest risk was actually impossible,” explained Craig Covey, Incident Commander and Orange County Fire Chief.
According to Covey, officials are preparing for two potential disastrous scenarios: the tank could fail, releasing 6,000 to 7,000 gallons of hazardous chemicals into nearby areas, or it might undergo “thermal runaway,” leading to an explosion that could trigger a chain reaction in adjacent tanks containing flammable materials.
“We’re organizing evacuations based on these two possibilities: failure or explosion,” Covey added.
While no gas leaks or toxic plumes were occurring at the moment, he advised residents to remain cautious and heed warnings without delay.
No timeline has been given regarding when a leak or explosion might happen.
Garden Grove Police Chief Amir El Farah noted that the evacuation zone was expanded to ensure public safety.
“The safety of our community is our top priority,” El Farah stated, emphasizing the need for community cooperation in resolving the issue effectively.
Emergency shelters were established for families displaced by the crisis in Garden Grove and Cypress.
Local law enforcement and support teams remain actively monitoring the unfolding situation. As of 1 p.m. local time, there were no reports of injuries or fatalities.
Representative Derek Tran, a Democrat from California, is closely following the chemical leak and is in regular contact with local emergency officials. He mentioned, “I have been in touch with federal disaster authorities, including FEMA and the EPA, to request any available federal assistance for Garden Grove.” Tran also advised residents to adhere to local authority directions and stay out of affected areas until further notice.
As of now, FEMA and the EPA have not made any immediate statements regarding the incident. This story is still developing, and updates will follow as new information becomes available.
