Officials have lifted all evacuation orders related to an overheating chemical tank in southern California, a day after a crack in the structure eliminated the risk of a catastrophic blast.

The threat of an explosion due to pressure and heat inside a volatile toxic chemical tank at a California aerospace facility has been eliminated.

The risk of a “catastrophic” explosion at a chemical tank in a Los Angeles-area city was averted by Monday, but around 16,000 people remained under evacuation orders as some risks remained, officials

While "that is incredibly positive news," an official said, authorities are warning that danger still persists in Southern California
