Authorities are working to confirm whether a crack in a tank is relieving pressure. If so, the risk of a boiling liquid expanding vapor explosion (BLEVE) decreases. The possibility of a BLEVE remains a concern, and efforts to confirm pressure release continue overnight. A confirmed release would reduce the evacuation zone, allowing focus on cooling the tank.
Air monitoring indicates no toxic air release from the possible fissure. Concerns persist over a potential rupture at GKN Aerospace, which could release toxic materials into waterways and vapors into the air.
According to the Orange County Fire Authority as of early Monday, one of three tanks has been neutralized with a compound. However, two, including the affected tank, remain unaddressed. Reports of multiple cracks have been refuted. Weather stripping peeling doesn’t indicate additional cracking. Monitoring confirms no current chemical leak.
A GKN Aerospace spokesperson stated crews are continuously working to mitigate leak risk. An explosion could trigger blasts in adjacent tanks holding methyl methacrylate, posing significant risks.
Concern centers on potential tank ruptures releasing toxic substances. Division Chief Craig Covey suggested it could be one of California’s worst chemical incidents. The blast radius, up to half a mile, would cause severe damage and toxic vapor dispersal. With 50,000 evacuees, shelters in Orange County are near capacity.
Lydia Green, an Anaheim resident, expressed fear and hardship without basic needs. Her partner, Eugene Smith, described their situation as a nightmare, fearing a catastrophic explosion. Nearby shelter resident Jaden Gebeleinis voiced anger about hazardous facilities near homes and hopes for effective management to avoid worst-case scenarios.
The American Red Cross reported shelters at or near full capacity. No return timeline is set for evacuees, with concerns initially sparked by a vapor release last Thursday.
Firefighters use sprinklers and hose lines to cool the tank, with temperatures appearing to exceed 100 degrees Fahrenheit. Gov. Gavin Newsom declared a state of emergency and requested federal support. Collaborative efforts aim to safely return families to their homes.
