In this 16 hour arc flash hazard analysis training class, Jim Phillips, P.E., takes you through the 2018 edition of the IEEE 1584.  Jim discusses the changes, walks you through the calculations with his calculation worksheets and how the 2018 edition is is used in arc flash studies.  You will see calculation details and be able to evaluate the differences between the 2002 edition and the 2018 edition as well as differences when changing parameters such as electrode configurations and enclosure sizes.

The Second Edition of IEEE 1584 is a major game changer.  Almost everything has changed since the original edition was introduced in 2002.

Highlights of the next edition include:

  • Five different electrode configurations to enable more detailed modeling
    • Vertical electrodes in a metal box/enclosure – VCB (also in 2002 Edition)
    • Vertical electrodes terminated in an insulating barrier in a metal box/enclosure – VCCB
    • Horizontal electrodes in a metal box/enclosure – HCB
    • Vertical electrodes in open air – VOA (also in 2002 Edition)
    • Horizontal electrodes in open air – HOA
  • More choices for enclosure types and sizes
  • Enclosure correction factor calculation to adjust for specific enclosure size
  • The effect of grounding has been eliminated
  • An arcing current variation factor calculation replaces the 85% factor
  • Calculations performed at 1 of 3 voltage levels with interpolation to actual voltage
  • The 125 kVA transformer exception was eliminated

Each calculation is performed in 2 steps which includes an initial calculation based on one of three voltage levels and a second calculation interpolating to the specific system voltage.    The 125 kVA “exception” was replaced.  Learn why and what has replaced it.  What about the 2 second rule?  Jim discusses all this and much more.

ArcFlash

What is an Arc Flash Study?

As part of an arc flash study (Risk Assessment) the incident energy exposure level is determined based on the working distance of the employee’s face and chest areas from a prospective arc source. Arc-rated clothing and other PPE is selected with a rating sufficient for the incident energy exposure and shall be used by the employee based on the specific task. IEEE Std. 1584 tm, IEEE Guide for Performing Arc Flash Hazard Calculations is the method used globally for calculating the prospective incident energy.
NFPA 70E and CSA Z462 also require determining the arc flash boundary, which is the distance from a potential arc source where the incident energy is 1.2 cal/cm2. This value is considered to be the point at which the onset of a second-degree burn occurs. Live work performed outside of the arc flash boundary does not require PPE, although the risk of some injury still exists.

The concept of these requirements is simple. At each location, the arc flash study is used to determine: The perspective incident energy exposure for a worker’s chest and face, the rating of PPE based on the perspective incident energy, the arc flash boundary.

Although NFPA 70E provides more generalized PPE tables as a simplified alternative for PPE selection, an arc flash calculation study requires performing calculations to estimate the magnitude of incident energy exposure. These calculations are based on specific details, including the available short circuit current, device clearing time, grounding, arc gap distance, equipment type, and many other factors.

This information, as well as data regarding electric shock protection and approach limits, can be included on the arc flash warning labels placed on the equipment under study. Before conducting energized work, a qualified worker can refer to the label and obtain the data necessary for the shock hazard risk assessment and the arc flash hazard risk assessment as required by NFPA 70E and CSA Z462.

Although an arc flash study can appear to be complex, it can be more manageable when broken down into basic steps as outlined in this training program.

Why Perform an Arc Flash Study?

According to OSHA 1910.132(d) The employer is responsible to assess the hazards in the work place, select, have, and use the correct Personal Protective Equipment (PPE) and document the assessment. The use of NFPA 70E and other related industry consensus standards has been used to demonstrate whether an employer acted reasonably when there is a possible OSHA enforcement action taken.

So although NFPA 70E is not directly part of OSHA standards, it can be used as evidence of whether an employer acted reasonably in complying with OSHA standards and addressing “recognized hazards”.

There are more specific links within the OSHA standards as well. A typical example is found in 1910.335, Safeguards for personnel protection which requires: “(a)(1)(i) Employees working in areas where there are potential electrical hazards shall be provided with, and shall use, electrical protective equipment that is appropriate for the specific parts of the body to be protected and for the work to be performed.”

This regulation requires that employees must be properly protected from potential electrical hazards, by using adequate PPE, but it does not provide specific detail of what specific personal protective equipment is necessary to achieve the objective. It might be considered that based on this generalized statement, the selection of the correct PPE is open to interpretation however, this would be incorrect and an Arc Flash study should be performed.
