Crews responding to the chemical emergency at a Southern California<\/a> aerospace facility discovered what officials described as a possible crack in the unstable tank that may be relieving pressure inside the vessel.<\/p>\n

In a video update posted to social media Sunday, Orange County Fire Authority Interim Chief T.J. McGovern said specialized teams entered the hazard zone late Saturday night on a reconnaissance mission and visually identified what appeared to be a crack in the tank at the center of the crisis.<\/p>\n

“What they found was a potential crack in the tank, which could potentially be relieving some of the pressure in there,” McGovern said.<\/p>\n

Officials are now working to confirm the discovery, which McGovern said could change the strategy for managing the incident.<\/p>\n

“With this new information, it could change our trajectory and our strategy to this event,” he said.<\/p>\n

The overnight operation marked one of the first successful close-range inspections of the tank since the emergency escalated Thursday night at GKN Aerospace in Garden Grove<\/a>, where crews have been racing to prevent a catastrophic failure involving methyl methacrylate, or MMA \u2013 a volatile and flammable plastic epoxy chemical.<\/p>\n

The leak was discovered at the aerospace manufacturing facility, which produces engine structures and components for commercial and military<\/a> aircraft.<\/p>\n

Authorities previously warned the deteriorating tank could either rupture and spill thousands of gallons of hazardous chemicals or explode during a “thermal runaway” event, potentially triggering neighboring tanks and creating a wider disaster.<\/p>\n

The discovery now presents what officials suggested could be a more favorable scenario than initially feared, though crews cautioned the threat has not yet passed.<\/p>\n

“We\u2019re not there yet, but this was a step in the right direction,” McGovern said.<\/p>\n

More than 40,000 residents remain under evacuation orders as officials continue monitoring temperatures, air quality<\/a> and structural conditions around the facility.<\/p>\n

Gov. Gavin Newsom<\/a> declared a state of emergency Saturday as crews shifted from defensive containment operations to high-risk offensive actions aimed at preventing an explosion.<\/p>\n

McGovern praised firefighters and hazardous materials specialists involved in<\/a> the overnight mission, calling the operation successful and emphasizing that public safety remains the top priority before residents can return home.<\/p>\n

“We want to get you back, but we cannot do that until it\u2019s deemed safe,” he said.<\/p>\n

Officials said additional updates are expected later Sunday as engineers and hazardous materials experts analyze the new findings.<\/p>\n
