Massive Fire at Chevron El Segundo Refinery Disrupts Jet Fuel Output in Southern California
A large fire erupted at Chevron’s El Segundo refinery, near Los Angeles, late Thursday night, sending flames and plumes of smoke visible for miles across the South Bay area. Officials confirmed that no injuries were reported and all plant personnel were accounted for.
How the Blaze Started and Spread
The blaze ignited in the Isomax 7 unit, which handles the conversion of mid-distillate fuel oil into jet fuel, according to Reuters. Eyewitnesses reported a loud explosion around 9:30 p.m. local time, followed by towering flames and a “sky turned orange” effect across the Los Angeles skyline. Firefighters responded rapidly, and the fire was largely contained within hours, though parts remained burning into the next morning. The cause of the ignition remains unknown as of this writing.
Scope, Capacity and Impact
The Chevron El Segundo refinery is one of the U.S. West Coast’s key fuel hubs. It handles about 285,000 barrels per day and supplies nearly 20 percent of motor vehicle fuel and 40 percent of jet fuel used in Southern California, including for LAX airport. Because California’s fuel supply is relatively isolated from other U.S. refining zones, even localized disruptions can ripple into broader supply constraints and price volatility.
Emergency Response and Safety Measures
Chevron deployed its own fire department along with local agencies in El Segundo and Manhattan Beach to fight the fire. Road closures were implemented around the site, and residents were initially advised to shelter in place. Officials later confirmed no evacuations were required, and air quality remained within safe limits. The facility remains under active monitoring, and authorities are investigating whether the blaze could escalate or cause residual hazards.
Supply Chain and Market Implications
The fire could squeeze jet fuel supply to Los Angeles International Airport (LAX) if the Isomax 7 unit remains offline for an extended period. Officials, however, said there was no immediate impact on LAX operations. Analysts suggest that while the fire is unlikely to derail the global oil market, localized fuel shortages could push gasoline and jet fuel prices higher in Southern California. To make up any shortfall, import routes from Asia into the West Coast are being considered.
Historical Context and Precedents
This is not the first time the Chevron El Segundo facility has experienced major fires. Previous incidents in 2022 and 2017 sparked concerns over aging infrastructure and maintenance safety practices. In 2025 alone, multiple U.S. refineries have faced fire incidents, highlighting ongoing industry risk from high temperatures, complex operations, and chemical volatility. Regulatory scrutiny over refinery safety standards has increased in recent years.
What to Watch and Next Steps
Key indicators in the coming days will include:
- Extent of damage to Isomax 7 and how long it remains offline
- Effect on jet fuel stocks entering LAX and region-wide supply chains
- Investigative findings on the cause (mechanical failure, maintenance lapse, external event)
- Any further fires or flare-ups in adjacent units or storage areas
- Fuel price movements in California and adjacent states
