Overview

  • An explosion around 9:30 p.m. PT ignited a blaze visible for miles at one of the West Coast’s largest refineries.
  • Chevron’s on-site team and local firefighters confined the fire to a single section, with the last visible flames out around 7:15 a.m. Friday.
  • A shelter-in-place for parts of Manhattan Beach was lifted overnight, and nearby roads were later reopened.
  • Air-quality readings showed no fence-line exceedances, and LAX said airport operations were unaffected.
  • The cause is under investigation, though some reports cite the refinery’s Isomax 7 jet-fuel unit as the possible origin.
