Summary Nr: 136398.015 Event: 06/18/2021Power Plant Worker Is Killed When Struck By Vessel Lid
At 6:30 p.m. on June 18, 2021, an employee was working for a firm that operated electric power generation facilities. He was working at a natural gas-fired powe r plant. He and a coworker were restoring a natural gas filter system at the pow er plant, by aligning valves after a maintenance crew had replaced filter media. This system separated liquids from the natural gas before the natural gas was b urned as fuel gas to heat water and produce steam for turbines. This was Filteri ng Unit A. It had been taken offline for the filter media replacement. It was a model number 95V-W12A-I-18-550-WP vertical dry gas scrubber, with tag number ONG 01FA.
