The Electrical Utility Risk Assessment Practice #250 is a best practice developed to define and evaluate the risk associated with working with medium\u2014and high-voltage activities in the DOE complex.<\/p>\n

Why was the best practice used? <\/strong>Electrical utility tasks involve high-hazard activities where the risk is often undefined. This best practice is developed to assess the risk of high hazard activities to assist DOE contractors in implementing controls to reduce risk. These controls follow the hierarchy of control methods defined in ISM and NFPA 70E. Additionally, human performance indicators and tools are utilized to address the human element of risk.<\/p>\n

What are the benefits of the best practice? <\/strong>Using this best practice will allow DOE contractors to evaluate their high-hazard tasks in order to reduce risk to an acceptable level. This best practice provides a common, systematic approach for all DOE contractors to evaluate their Electrical Utility Operations. Making use of this systematic approach will enable each site to implement adequate work control to ensure the proper rigor, staffing, and work method controls are in place and implemented for appropriate high-risk activities.<\/p>\n

What problems\/issues were associated with the best practice? <\/strong>NFPA 70E requires electrical activities to go through a risk assessment process; however, Electrical Utility Operations are exempted from those requirements. Electrical Utility Operations are among the highest hazard activities performed on DOE sites. This is developed to evaluate the risk of EUO high hazard tasks and provide methods for implementing risk control.<\/p>\n

How was the success of the Best Practice measured?<\/strong> This best practice was developed using several experienced EUO personnel from multiple DOE sites.<\/p>\n

Description of process experience using the Best Practice: <\/strong>The known operating experience to date is limited to a few sites associated with the development of this product that have successfully employed some or all of the components of this Best Practice at their respective sites.<\/p>\n

Scope and Applicability<\/h2>\n

The best practice applies to Electrical Utility Operations (EUO) at United States Department of Energy (DOE) sites. The risk assessment herein covers the scope of high hazard electrical work not covered by NFPA 70E Electrical Safety in the Workplace. [See Roles and Responsibilities]<\/em><\/p>\n

Note: The information provided is intended to be modified by each facility to meet their applicable mission, roles, staffing, and tasks.<\/p>\n

Performing a Risk Assessment for High Hazard Electrical Utility Operation Tasks:<\/h2>\n

Identify the Scope and Hazards<\/strong><\/p>\n

    \n
  1. Identify the scope of work that will be assessed for risks.<\/li>\n
  2. Perform a planning walk-down and\/or table-top to identify hazards (shock, arc flash, environmental, chemical exposure, work from heights, etc.) associated with the task(s). Involve appropriate SMEs, as needed.<\/li>\n
  3. Identify possible situations that could develop into accidents during work task, considering serious\/high-impact, but credible, scenarios.<\/li>\n<\/ol>\n

    Categorization<\/strong><\/p>\n

      \n
    1. Using Table 1, organize scenarios into one of the following three categories according to what would be impacted by an accident: More than one may apply.<\/li>\n<\/ol>\n
