A huge fire broke out on Thursday night at a Chevron oil refinery in California, one of the largest on the U.S. west coast, following reports of an explosion. No injuries were reported from the incident at the El Segundo plant, Chevron said on Friday, with the U.S. energy major’s fire department personnel and emergency services “actively responding” to the situation. “All refinery personnel and contractors have been accounted for and there are no injuries,” Chevron said in a statement, according to NBC. The El Segundo oil refinery is capable of refining 290,000 barrels of crude oil per day, Chevron says on its website, and its primary products are gasoline, jet and diesel.
