A study shows U.S. oil refineries have an ongoing problem with accidents that turn deadly, losing four times as much money from such incidents than refineries in the rest of the world.
The insurance company report was obtained Friday by The Associated Press.
Federal officials say the problem is highlighted by a string of deadly explosions, including one that killed five people Friday at a Tesoro Corp. refinery in Washington state.
The cause of the blast was under investigation. The blaze started during maintenance work on a unit that processes highly flammable liquid derived during the refining process.
Six investigators with the U.S. Chemical Safety and Hazard Investigation Board were dispatched to the scene.
