More than 40,000 people have been evacuated after a toxic chemical started to leak from a tank at an aerospace manufacturing facility in the US.
tank in southern California contains an estimated 7,000 gallons of methyl methacrylate, a highly volatile and flammable substance used in the production of plastic.
The Orange County Fire Authority (OCFA) issued initial evacuation orders for the area surrounding the Garden Grove facility on Thursday afternoon, after reports of a tank temperature increase.
The evacuation zone has been expanded and the cause of the leak is being investigated.
OCFA officials say there are three tanks at the facility, one of which has a compromised cooling system.
In a press conference on Friday afternoon, OCFA Chief Craig Covey said there were two potential outcomes from the leak, the first being that the tank fails and spills “very bad chemicals” into the area surrounding the facility.
