Arc Flash Hazards

An Arc Flash Analysis is the cornerstone of any electrical safety program and is critical to ensuring that your facility is in compliance with industry standards and new arc flash safety requirements. Without this analysis and and an understanding of the available fault current and protective device clearing times, it is not possible to select the proper Personal Protective Equipment (PPE) for your personnel. For this reason, the following Standards now mandate that employers assess the arc-flash hazards to their employees:

OSHA 29 CFR 1910.132 (d) requires that employers evaluate their workplace to determine whether hazards exist, and that employees utilize the appropriate PPE for these hazards. Written certification is required to verify that a hazard analysis has been conducted for each particular location of the facility.

NFPA 70E requires that an Arc Flash Analysis be performed to protect employees from injury and to determine the appropriate level of PPE.

NESC Part 4, Section 41 requires that – effective January 1, 2009 – employers ensure that an analysis is conducted to determine the potential exposure to an electric arc for employees who work on or near energized parts of equipment.

In addition to identifying the appropriate PPE for personnel at each location in your facility, through an Arc Flash Analysis it is also possible to identify opportunities for reducing / mitigating incident arc-energy levels at locations that exceed PPE Level 2. Powerserve Inc. has the tools and experience to conduct such an analysis.

What we will do:

  • Identify the equipment locations where an arc flash analysis is required
  • Collect the required data at each location
  • Prepare a system model and single-line diagram
  • Prepare a short-circuit study to determine available fault currents
  • Prepare arc flash calculations per NFPA 70E and IEEE 1584
  • Identify appropriate PPE per risk levels defined in NFPA 70E
  • Propose arc flash mitigation solutions for eqpt that exceeds PPE Level 2
  • Calculate the arc flash protection boundaries
  • Document results and provide appropriate equipment labels
  • Provide technical and safety training on arc flash hazards
