Authorities in Southern California are working urgently to prevent a possible explosion after a chemical tank at GKN Aerospace in Garden Grove overheated and began leaking vapors.
The tank contained 6,000–7,000 gallons of methyl methacrylate, a volatile compound used in plastics. Around 50,000 residents were evacuated as a precautionary measure.
Firefighters have been continuously spraying water to cool the tank, while officials note that a crack in the tank may be relieving pressure, reducing the likelihood of a catastrophic blast.
Governor Gavin Newsom has declared a state of emergency, and federal assistance has been requested from President Donald Trump to support local efforts.
Air monitoring indicates pollution levels remain within normal limits, but the situation is still considered high-risk until the tank stabilizes fully.
Health experts warn that exposure to methyl methacrylate can cause lung, skin, and eye irritation, nausea, and dizziness. Environmental teams are deploying sandbags and barriers to prevent contamination of storm drains and waterways.
Authorities continue to monitor the tank’s temperature, air quality, and structural integrity, while displaced residents are being sheltered in schools and community centers until conditions are deemed safe.
