Authorities in California have found a crack in a tank containing 26,000 liters of methyl methacrylate, a volatile chemical, which may relieve pressure and reduce the risk of an explosion. This discovery comes after approximately 40,000 residents in the Garden Grove area of Orange County were evacuated on May 22 due to a leak that began earlier in the week. The tank is located about five miles from Disneyland, raising concerns about public safety in the densely populated area. Firefighters have been spraying water on the tank to cool it down, as it was heating up, heightening fears of a catastrophic blast. The Orange County Health Officer emphasized the necessity of the large exclusion zone around the tank, while shelters have been opened for evacuees. Governor Gavin Newsom declared a state of emergency for Orange County, urging residents to heed evacuation orders. The leak originated at the GKN Aerospace facility, which focuses on manufacturing and testing aircraft components. GKN has expressed regret for the disruption caused to local residents and businesses.
