388200 02: Spectators on Signal Hill watch as toxic smoke blows over downtown Long Beach, CA, April 23, 2001, from a fire at the Tosco oil refinery in Carson, 15 miles south of Los Angeles. The refinery was running at full capacity, around 125,000 barrels of oil per day, when a blaze broke out in the ''coker'' unit, where petroleun coke is burned in the making of gasoline. Lost production could add to the recent spike in gasoline prices, which analysts say could hit $3 a gallon or more. (Photo by David McNew/Newsmakers)
