Description:A 43-year-old assemblyman died on May 26, 1999 from chest injuries he received earlier that day when struck by a high pressure water jet emitted after the failure of a gasket during a hydrostatic test of a cooling coil for an air cooled heat exchanger. At the time of the incident the victim was part of a two-man team conducting the hydrostatic test at a heat exchanger manufacturing company. The laborer was positioned on a stepladder near the heat exchanger coil manifold to close an isolation valve on the pressure line connected to the manifold flange when the gasket failed, releasing a high pressure water jet in the direction of the worker. The water struck the assemblyman in the chest knocking him approximately 20 feet off the end of a loading dock onto the concrete drive below. Another employee nearby immediately contacted 911 by mobile phone and the victim was evacuated by helicopter to a local hospital where he died from injuries sustained in the incident. Face investigators concluded that, to help prevent similar occurrences, employers should: 1. Incorporate specific safe work practices into the work instructions for setting up and conducting hydrostatic testing, and train workers in those practices
2. Provide the proper materials and equipment for use in performing high-risk work
3. Analyze or otherwise investigate critical system failures and take corrective action to prevent future occurrences
and 4. Provide barrier protection for employees who must work in close proximity to potentially weak points in the hydrostatic test system or provide a remote control to physically separate the employee from the high-risk area.
