Firefighters Still Working to Cool Garden Grove Chemical Tank
The situation has grown more urgent as temperatures inside the compromised tank have continued to rise, reaching about 90 degrees Fahrenheit (32.22 degrees Celsius) on Saturday from 77 degrees (25 degrees Celsius) a day earlier.
About 50,000 people in Orange County have been told to evacuate, with many spending the Memorial Day weekend in shelters, hotels or with friends and family outside the danger zone.
If that is not possible, Purdue University engineering professor Andrew Whelton said it would be best if the tank sprang a leak so the chemical could be mostly contained.
About 40,000 Californians were forced to evacuate their homes on Friday following a leak from a chemical storage tank in the southern part of the state.
