I just read a news article about 40 thousand people being evacuated because of a "temperature rise" and a "bulge" in a 7000 gallon chemical tank.
"The Orange County Fire Authority (OCFA) issued initial evacuation orders for the area surrounding the Garden Grove facility on Thursday afternoon, after reports of a tank temperature increase."
