Text For Citation: 01 Item/Group: 002 Hazard:

29 CFR 1910.269(a)(2)(i)(A): Each employee was not trained in, and familiar with, the safety-related work practices, safety procedures, and other safety requirements in this section that pertain to his or her job assignments: (a) Heat Recovery Steam Generator (HRSG) - On or about April 29, 2025, and at times prior thereto, at the Calpine Hay Road combined cycle facility, the employer did not ensure that employees assigned to perform maintenance on the low-pressure (LP) drum of HRSG Unit 6 were adequately trained and familiar with safety-related work practices required for the safe opening of inward-swinging manway doors on pressure vessels that may retain vacuum or residual pressure after shutdown. Operators had not been trained to recognize that a drained HRSG drum can develop a vacuum during cool-down, nor in the specific methods to verify and equalize pressure using vent valves before removing bolts and strongbacks. They were not instructed on staged bolt removal, stand-clear procedures, or the requirement to verify zero energy by both instrument and physical venting prior to breaking the seal. As a result, employees worked on a vessel that was not verified at atmospheric pressure, and an operator was fatally struck when the manway door was violently drawn inward by vacuum suction.
