Friday morning brought renewed and wider evacuation orders in Garden Grove after responders found valve damage on a leaking methyl methacrylate tank at GKN Aerospace.
Incident commanders said the unsecured tank is "actively in crisis" and could either fail, spilling up to 7,000 gallons of toxic chemicals, or explode and hit nearby chemical tanks.
Firefighters had initially cooled the overheated tank with hoses and briefly allowed residents to return Thursday evening before conditions worsened again.
More than a dozen schools were closed and two evacuation centers opened as Orange County authorities urged residents to leave the affected area.
The leak stems from a larger 34,000-gallon tank at the aerospace plant about 35 miles south of Los Angeles, underscoring ongoing industrial-safety risks in a dense suburban area.
