ARC FLASH - Hazard Analysis Service
An arc-flash analysis assessment is critical to the safety of your employees and to ensure that your facilities are in compliance with industry standards. Unless a realistic determination of the available fault current and protective device clearing times are made at each of your equipment locations, it`s not possible to select the proper Personal Protective Equipment (PPE) for your electrical workers. Qualified personnel are needed to properly perform all aspects of an arc-flash hazard analysis assessment and propose solutions for reducing incident arc-energy levels at locations that exceed PPE Level 2, typically electrical engineers having a thorough understanding of the short-circuit behaviour of power systems, protective device coordination, and arc-flash mitigation techniques.
As specialists in electric power switching and protection, Arc Flash Advisors engineers are well qualified to prepare such assessments. We have the expertise to:
- Identify the equipment locations where an arc-flash hazard analysis is required
- Collect pertinent data at each location
- Prepare an appropriate system model and single-line diagram
- Prepare a short-circuit study to determine the three-phase bolted fault current at each location
- Prepare arc-flash calculations in accordance with NFPA 70E and IEEE 1584, using SKM Power Tools
- Determine appropriate PPE in accordance with risk levels defined in NFPA 70E
- Propose arc-flash mitigation solutions for locations that exceed PPE Level 2
- Calculate the arc-flash protection boundary distance
- Document the results and provide appropriate equipment labels
- Provide technical and safety training on arc-flash hazard
- Compliance: The analysis complies with OSHA, NFPA 70E, NEC 110.16, CSA Z462 and IEEE 1584 requirements, following the NETA recommendations.
Study Report:
- Following the recommendations of NETA, the results of the arc-flash study shall be summarized in a final report containing the following items:
- Basis, method of hazard assessment, description, purpose, scope, and date of the study
- Tabulations of the data used to model the system components and a corresponding one line diagram
- Descriptions of the scenarios evaluated and identification of the scenario used to evaluate equipment ratings
- Tabulations of equipment incident energies, hazard risk categories, and flash protection boundaries. The tabulation shall identify and clearly note equipment that exceeds allowable incident energy ratings
- Complete Arc Flash Analysis of your electrical panels
- Single or One-Line Diagram of the electrical distribution panels in your system
- Labeling of your Electrical Panels with OSHA and ANSI approved warning labels
- Complete Report of the Arc Flash Study for your records
- Arc Flash PPE Purchase advisory report and PPE supply
- Full Compliance of NFPA 70E and OSHA 1910 Arc Flash Regulations
- Conclusions and recommendations
