ARC FLASH Compliance


what matters the most

Arc Flash Hazard has proved to be a significant and dangerous threat to electrical personnel. Severon’s Arc Flash Compliance program provides a comprehensive safety solution that helps you ensure that all of the arc flash requirements are met effectiviely. A Deadly Force Arc Flash is a result of a rapid release of energy caused due to an arcing fault between live electrical conductors. Arc flash is initiated by an external trigger that creates a conduction path for the arcing current. This may occur as a result of a human error, such as the accidental contact of a test probe between an energized conductor and earth or an equipment failure, such as insulation breakdown. The energy discharged in an arcing fault can be significant. Associated hazards include, extreme radiant heat (reaching temperatures of up to 4 times the surface of the sun), explosive pressure waves, shrapnel and toxic gasses.

Industry Standards Many industries have already established and implemented enterprise wide arc flash compliance programs that ensure employee safety in the event of an arc flash. Several international standards cover the methods used to calculate energies resulting from arc flash incidents. These standards include: NFPA 70E Standard for Electrical Safety Requirements for Employee Workplaces


IEEE Standard 1584 A Guide for Performing Arc Flash Hazard Calculations


Actions To Take Good safety plans involve adherence to the following six-point plan: 1 Asset owners are able to demonstrate an implemented safety program with defined processes that address arc-flash hazards.

2 Documented calculations of the degree of arc flash hazard (incident energies) and the associated PPE requirements.

3 Issue appropriate PPE to workers based on the degree of arc flash exposure at the place where electrical work is to be carried out.

4 Train workers on the hazards associated with electrical work including electric shock and arc flash.

5 Provide appropriate tools, if employees are required to work on live electrical equipment (Live testing, fault finding etc...).

6 Affix arc flash warning labels on equipment where electrical work could be performed.

ARC FLASH STUDIES Arc Flash Hazard Analysis Severon maintains a high level of engineering expertise in arc flash analysis. The company has implemented enterprise-wide analysis for several customers. Severon’s arc flash compliance program includes: g






Deploying field-based resources to gather electrical system data necessary to complete the arc flash study. Using the gathered data to accurately model the power distribution system, calculating short-circuit currents and coordinating over current protective devices. Using the power system model to calculate incident energies at various locations across your power system. These calculations are performed in accordance with NFPA 70E or IEEE1584 requirements and include parameters such as flash protection boundary, incident energy and associated hazard risk category. Providing detailed recommendations and strategies to mitigate arc flash hazards while evaluating options for reducing the incident energy as per client’s operational requirements. Supplying and/or installing equipment warning labels that define the calculated flash protection boundary, incident energy and hazard risk category for each electrical equipment. Presenting the study results and providing site specific arc flash hazards and safety training to personnel who operate and/or maintain electrical equipment.

Severon’s highly-qualified power systems engineers (PSE) have extensive experience in performing Arc Flash studies. All PSEs have access to a variety of analysis tools used to best address the safety risks of your unique system. Our combined use of commercial and proprietary software utilizes IEEE and NFPA equations and methods that are comprehensive and accurate for calculating parameters including fault current momentary duties, device clearing times, arcing fault currents, arc durations and incident energies.

ARC FLASH TRAINING PROGRAM Education: A Key to Better Arc Flash Safety Severon’s arc flash safety training helps you understand what Hazard Risk Categories, incident energies and flash protection boundaries mean to you. You can then use this knowledge to choose the right personal protective equipment (PPE) in accordance with NFPA 70E and local safety requirements. We specialise in offering customized trainings, specifically designed to suit your company’s unique requirements and address your site hazards. If it’s not practical for your staff to train at one of Severon’s facilities, we would be glad to offer you a more workable alternative. Severon’s “Understanding ArcFlash” training program covers: g

Standards used to determine Safe Approach Distances


Methods for calculating Prospective Short Circuit Current


How to calculate Flash Protection Boundary and Incident Energy


Determining Hazard Risk Category (HRC)


Selecting PPE using Incident Energy value and the PPE Matrix


Arc Ratings for common types of garments used in the industry
