Potential Crack in Tank Discovered at Southern California Aerospace Facility

Emergency crews addressing a chemical hazard at a Southern California aerospace site found what officials describe as a potential crack in an unstable tank. This crack may be easing pressure inside. In a video shared on Sunday, Orange County Fire Authority Interim Chief T.J. McGovern explained specialized teams observed this crack during a night inspection on Saturday.

What they found was a potential crack in the tank, which could potentially be relieving some of the pressure in there, McGovern noted.

Officials are verifying this finding, which might influence their response strategy. According to McGovern, this development could alter their approach to managing the incident.

The close-range inspection represents a significant step since the emergency escalated last Thursday evening at GKN Aerospace in Garden Grove. Crews have been striving to prevent a major mishap involving methyl methacrylate (MMA), a flammable epoxy chemical.

The chemical leak occurred at the facility, which manufactures components for aircraft engines used in both commercial and military sectors. Authorities previously cautioned that the deteriorating tank might rupture, releasing thousands of gallons of harmful chemicals, or explode in a thermal runaway event, risking nearby tanks and exacerbating the situation.

The discovery of the crack provides a potentially better scenario than feared, though officials stress the situation remains perilous. “We’re not there yet, but this was a step in the right direction,” McGovern stated.

State of Emergency Proclaimed

In response to the ongoing chemical emergency, Governor Gavin Newsom declared a state of emergency in Orange County.

More than 40,000 residents are still under evacuation orders. Officials continue monitoring key environmental factors around the facility. Newsom’s declaration follows the shift from containment operations to high-risk actions to prevent an explosion.

McGovern commended the firefighters and hazardous materials teams for their successful night mission and reaffirmed that public safety remains a priority before residents can return home. “We want to get you back, but we cannot do that until it’s deemed safe,” he confirmed.

Further updates are anticipated as engineers and specialists assess the latest findings.
