After a five-day emergency, Orange County officials have declared the evacuation zone safe for most residents, allowing nearly 34,000 of the 50,000 people evacuated to return home. Orange County health officer Dr. Regina Chinsio-Kwong reassured residents, stating, "I want to reassure everyone who is outside of the new evacuation zone that when you go home, you can feel safe."23

Officials determined that the damaged chemical tank will not cause a massive explosion, easing concerns among the community as there were no fumes, no vapors, and no contamination reported from the incident. However, around 16,000 residents remain under evacuation as precautions continue to avoid risks of fire, leaks, or small explosions. Hazmat Branch Division Chief Nick Freeman confirmed the tank’s temperature is currently around 50 degrees, significantly lower than the peak of 100 degrees during the crisis. The five-day crisis underscored the importance of ongoing vigilance as residents transition back to normalcy in their communities.6
