Garden Grove chemical tank cooling raises hope as thousands evacuated in Orange County

Emergency crews are cooling a leaking toxic chemical tank at Garden Grove's GKN Aerospace, prompting evacuations for about 40,000 Orange County residents and several shelters in Garden Grove and nearby cities. Authorities warned the tank could either spill thousands of gallons or explode, but cooling efforts have reduced the temperature and responders are working overnight to mitigate the hazard. Residents are advised to follow advisories and avoid the affected area while air quality is monitored.
