In brief
California Governor Gavin Newsom has declared a state of emergency amid a critical situation at an aerospace manufacturing facility in Garden Grove, where a 7,000-gallon tank of methyl methacrylate—a highly volatile chemical—is bulging and heating rapidly. Orange County Fire Authority Chief Craig Covey warned of two dire scenarios: a catastrophic tank rupture or explosive thermal runaway. Temperature readings confirmed the internal tank temperature had risen to 32°C (90°F), climbing by one degree per hour despite emergency water sprays. Over 5,000 residents were evacuated, schools closed, and major roads shut as authorities built containment barriers to prevent chemical runoff. Health officials warned of respiratory risks from the chemical's distinctive 'fruity and heavy smell' but confirmed safety outside a one-mile perimeter.
California Governor Gavin Newsom declared a state of emergency on Friday as fire crews raced to prevent a potentially catastrophic failure of a toxic chemical tank at an aerospace manufacturing facility in Garden Grove. The incident involves a 7,000-gallon container of methyl methacrylate—a highly volatile chemical used in plastic manufacturing—that had bulged and was heating dangerously, prompting immediate evacuation orders for thousands of residents.Orange County Fire Authority Chief Craig Covey described the critical situation: 'The tank was rising in temperature, and we were facing two scenarios: does it rupture and spill, or does it blow up?' He confirmed internal temperatures had reached 32°C (90°F)—up from previously estimated 16°C (61°F)—and were increasing by one degree Fahrenheit hourly. 'Letting this thing just fail and blow up is unacceptable to us,' Covey emphasized, explaining crews were spraying the tank with water and constructing containment barriers to prevent any chemical runoff into storm drains or the ocean.The facility, operated by UK-based aerospace supplier GKN Aerospace, is located approximately 5 miles from Disneyland, which remained open as it lay outside the evacuation zone. Authorities reported an 'inoperable valve' had compounded the crisis, with local schools closed and major road exits restricted to limit access. Health Officer Dr. Regina Chinsio-Kwong warned residents to report 'a fruity and heavy smell' while acknowledging that exposure to vapors could cause respiratory issues and dizziness, though those outside the one-mile evacuation perimeter were deemed safe.Resident Mark Olsen recounted the urgency: 'I was woken up by the sirens... then told to evacuate. Not knowing when I could return home was really frustrating.' GKN Aerospace issued an apology, stating: 'We are fully focused on working with emergency services to ensure the safety of the local community, our employees and everyone else involved.'The incident underscores ongoing industrial safety concerns in California's manufacturing hubs, with officials stressing that while the situation remains tense, containment efforts are progressing as crews work to stabilize the failing tank before further escalation.}
