A significant fire erupted at the Chevron refinery in El Segundo, Southern California, late Thursday, sending a large fireball into the sky. Refinery personnel are accounted for with no injuries reported. While the cause is under investigation, officials are coordinating with local and state agencies to ensure community safety. No evacuation orders are in place, and air quality monitoring shows no detected exceedances at the facility's fence line. A temporary shelter-in-place was issued for a small area of Manhattan Beach as a precaution.
