Blast at Total's Gonfreville refinery injures five

French oil and gas company Total said on Monday that a gas leak at its 247,000 barrels-per-day Gonfreville refinery in Normandy had caused an explosion that injured five workers. The blast in northern France occurred during a scheduled maintenance work on a gas compressor, Total said, adding that emergency services were on site to contain the gas leak and fire. "There is no risk of it spreading within or outside the site," Total said in a statement.
