Safety Board Faults Cleaning Practice In Fatal Explosion

摘要

The practice of using flammable natural gas to clean power plant piping, which led to a fatal explosion in February, is commonly used at gas-fired power plants. That's among conclusions of the U.S. Chemical Safety Board (CSB), which concluded a report on the explosion, which killed six workers and injured at least 50 others at Kleen Energy in Connecticut.rnAccording to CSB, the explosion occurred during a "gas blow," a planned effort to clean out new fuel-gas piping by directing high-pressure natural gas through the pipes and out of vents near ground level.
