VIDEO — California: 40,000 Under Evacuation Orders Due to Toxic Chemical Leak

Approximately 40,000 residents of Garden Grove, California, were under evacuation orders due to a leak from an aerospace facility’s storage tank, which has created a dangerous situation.

Officials have been working to figure out how to stop the tank that holds chemicals used to make plastic parts from exploding once it overheated on Thursday and vented vapors into the air, the Associated Press (AP) reported Saturday.

Orange County Fire Authority Division Chief Craig Covey said the tank could crack or blow up but authorities were unsure of a timeline.

“This thing is going to fail, and we don’t know when. We’re doing our best to figure out when or how we can prevent it,” he added.

Aerial video footage showed firefighters spraying the tank with water to keep its temperature low, per CBS LA. The outlet noted officials were monitoring air quality in the area:
