Firefighters ​contending with an overheating ‌tank of ​hazardous chemicals in southern California on Monday said an overnight operation ‌had eliminated the possibility of the tank exploding.

The tank of highly flammable methyl methacrylate began overheating on Thursday at ‌the GKN Aerospace facility in Garden Grove, a city ‌of about 172,000 people roughly 20 miles (35 km) south of Los Angeles. By Saturday, California Governor Gavin Newsom had declared ⁠a state ​of emergency ⁠and evacuation orders had been issued for an area home to ⁠tens of thousands of people as fears mounted that the ​tank could rupture and spill up to ⁠7,000 gallons (26,500 liters) of toxic material or explode and endanger nearby ⁠tanks.

Firefighters ​celebrated the appearance of a crack in the tank over the weekend, which helped relieve ⁠pressure, and the tank had cooled slightly. "That is incredibly positive ⁠news," Craig ⁠Covey, a division chief at the Orange County Fire Authority, said in a ‌video statement.
