Chemical Tank Blast Risk Eases in California After Pressure Drops

US officials said the risk of a chemical tank explosion in California has been greatly reduced after a crack that formed in the tank over the weekend relieved pressure inside it. The development eased fears around the site, where an emergency evacuation order remains in effect. Orange County fire officials said overnight assessments produced positive results, but stressed that the evacuation order is still active. Residents who have not yet left the area were warned by the mayor of Garden Grove about the danger. The tank began overheating and releasing steam last Thursday, prompting the evacuation of nearly 50,000 people. The incident quickly escalated into a major public safety emergency in the area. As the risk zone expanded, Governor Gavin Newsom declared a state of emergency in California. Authorities continued monitoring the situation as crews worked to assess the tank and surrounding area.
