At 1:00 p.m. on December 16, 2022, an employee monitored the start-up and operations of a high-pressure Water Tube Generator Boiler in preparation for an anticipated winter storm. A threaded plug on the boiler wall failed during the boiler’s start-up as system pressure was building, allowing the release of high-temperature and high-pressure steam. The steam sprayed the employee and resulted in severe burns to approximately 80% of his body. The employee was transported to the hospital but died due to complications from the burns.
