Oct. 3 (UPI) — A large fire broke out at a Chevron refinery in El Segundo, Calif., Thursday night, causing road closures and shelter-in-place orders.

The fire began at 9:30 p.m. PDT and was contained by morning, and there were no injuries, officials said.

The refinery has its own fire department, which used remote control water lines to keep the fire from spreading to other parts of the industrial site.

A shelter-in-place order was issued for nearby Manhattan Beach. Residents were told to close doors and windows and keep pets inside.

“We have zero reported injuries, and all workers and contractors are accounted for,” said El Segundo Mayor Chris Pimentel. “We rehearse these things in conjunction with Chevron all the time. We do a full sweep of disaster preparedness drills. Everything from spills in the ocean to fires at the refinery.”

The fire is believed to have originated from an isolation unit at the refinery, said Holly Mitchell, Los Angeles County Supervisor.
