HazMat crews investigated a massive flaring at a refinery in Torrance, CA, caused by an electrical disturbance on Wednesday, officials said.
Torrance firefighters responded to the ExxonMobil refinery just before 6 p.m. after the flaring began.
Southern California Edison said a Mylar balloon hit a power line in the Torrance area, causing a “system disturbance” which resulted in a voltage dip.
“Operations were interrupted, so they can’t just hit a button and shut the flow off of everything. So they divert the hydrocarbon to the flares,” said Battalion Chief Bob Millea with the Torrance Fire Department.
Fire crews monitored air quality levels in the area as the flame continued to burn.
As a result of the flaring, firefighters closed off local streets around the facility.
The all-clear was given around 2 a.m. Thursday, and all roads have since reopened.
