Large fire erupts at Chevron refinery in El Segundo

A massive fire was burning at a Chevron refinery Thursday sending large flames and a dark plume of smoke up into the air in El Segundo.

The fire erupted around 9:30 p.m. at the refinery in the 300 block of West El Segundo Boulevard, the El Segundo Police Department said.

There were no injuries at the refinery and all personnel were accounted for, the company said in a statement late Thursday, adding that a monitoring system indicated the fire did not move beyond the facility’s fence line

By early Friday, the fire was contained and there was no threat to public safety, the city said in a statement. No evacuations had been ordered.

While the exact reason for the fire is still unclear, the fire is believed to have originated from an isolation unit in the refinery, according to LA County Supervisor Holly Mitchell.

“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 city of Manhattan Beach issued a shelter-in-place order as a result of the fire. Macy Jenkins reports for the NBC4 News at 11 p.m. on Oct. 2, 2025.

Neighbors tell NBC4 they heard a loud bang before seeing the orange glow coming from the refinery.

“I never ever fear anything. This (fire), I got in panic mode when I saw it,” a neighbor told NBC4. “It looked like about 7 to 10 football fields wide of a flame and smoke billowing in the air.”

Several LA County Fire and El Segundo Fire Department crews were on scene to assist with the fire. LA County Supervisor Holly Mitchell said fire crews had contained the blaze to one section of the refinery.

A shelter-in-place order for nearby Manhattan Beach south of El Segundo was lifted Friday.

No immediate air pollution problems were detected. An air quality index map Friday showed good levels for the Los Angeles area, according to the South Coast Air Quality Management District.

The refinery covers roughly 1.5 square miles and has more than 1,100 miles of pipelines, according to the company’s website. The refinery, which has been in operation since 1911, can refine up to 290,000 barrels of crude oil per day, including gasoline, jet and diesel fuels, according to the company’s website.
