PowerHawke, Inc.’s staff of electrical and professional engineers can complete an Arc Flash Risk Assessment and/or Coordination Study for your facility completely in-house. This assessment is performed within NFPA 70E Standard for Electrical Safety in the Workplace 2015 edition.
An Arc Flash Risk Assessment will analyze the condition of your electrical equipment and pinpoint areas of and levels of risk for arc flash. Estimates are provided for: (1) arc flash boundary distance, (2) arc flash incident energy at typical working distances, and (3) the required level of Personal Protective Equipment (PPE) at each piece of equipment in the distribution system. PowerHawke performed analysis per the recommendations of IEEE 1584-2002 and protection requirements in NFPA 70E-2012.
Under OSHA’s General Duty Clause, the employer is required to complete an arc flash hazard assessment to identify risks in their electrical system and mitigate those systemic risks. As a result of the AFRA, your system devices will be labeled with information on Arc Flash and Shock Hazards. Even if you have not yet had an Arc Flash Risk Assessment, at minimum all devices should have generic arc flash warning labels as required by code. However, until you have a complete assessment, you may never know the risk poised by each piece of gear.
In addition to labeling, you will receive a comprehensive report which includes details of the analysis, a computerized system model, discussion of the study results, and recommendations for mitigation. PowerHawke can also conduct customized training for site personnel based on the results of the AFRA study.
The investment in an Arc Flash Risk Assessment is largely driven by the field work required to visit and catalog every device into a working model. The size, complexity and how physically spread out an electrical system is constitutes a big portion of the work. Typically, simple buildings can run in the $5,000 – $10,000 range and multi-site, multi building campuses can run into the six-figure range. Data collection for an AFRA can be performed in conjunction with our energized or deenergized services at a cost savings to the customer. Additionally, if you have electricians on staff, they can supplement or assist in the data collection process for efficiency and cost savings.
