Arc Flash Analysis/Study - IEEE 1584 Update

Arc Flash Analysis

Arc flash analysis is commonly known as an electrical engineering "arc flash study" or "short circuit study" that allows commercial and industrial buildings and industrial facilities to fulfill OSHA 1910 132(d) and CSA Z462/NFPA 70E requirements for determining the potential for workplace arc flash.

You can access the live online training through our web-based platform from your own computer. You can see and hear the instructor and see his screen live.

You can interact and ask questions. The cost of the training also includes 7 days of email mentoring with the instructor.

Electrical safety is the focus of this 12-hour live online training course. First, you will learn to identify requirements and responsibilities from safety standards and codes (CSA Z462, NFPA 70e, IEEE 1584, NESC 410A). Next, you will examine methods for identifying and calculating arc flash hazards. Finally, we will analyze equipment selection and operational strategies to reduce risks.

UPDATE:  IEEE-1584-2018, IEEE Guide for Performing Arc Flash Hazard Calculations, was just released with the document’s first update in 16 years! In this course, we will also look at the impact the new release will have on those using IEEE-1584 to perform hazard calculations.

An arc flash analysis study is usually performed through the collection of data from existing electrical equipment and systems, followed by the proper calculation of arc flash hazards and requirements by an experienced electrical engineer. This can be done using either the manual method using IEEE 1584 calculations or using popular arc flash study/short circuit study analysis software.

An effective arc flash analysis training program should provide electrical engineers with the knowledge and understanding of how to perform such an analysis/study.

Performing arc flash hazard analysis study on an electrical distribution system is cruicial to understanding the potential arc flash hazard of electrical equipment.

An arc flash analysis study is not a one-time event, but rather it is just a snapshot of the electrical system at one specific point in time. Any changes to the electrical system can potentially affect the accuracy of the arc flash analysis.

But once arc flash analysis study in place, it must be maintained if it is to remain effective. Updating the Arc Flash Anaysis Study program maintenance involves two critical elements: the study itself and electrical worker safety training.

CSA Z462 Standard for Electrical Safety in the Workplace specifies that arc flash hazard analysis shall be updated whenever there is a major modification or renovation to the electrical system (e.g., changing a feed or adding large motors). Even in the absence of such changes, CSA Z462 still mandates reviewing the arc flash study a maximum of every five years to account for the many little changes that can have a big impact on study results.


“Retraining” in NFPA 70E/CSA Z462

Like as in the case of the arc flash analysis study, proper training of qualified electrical workers in NFPA 70E/CSA Z462 is not a one time event. Workers leave; new ones are added; people simply forget what they have learned.

CSA Z462 specifies additional as-needed worker training under certain conditions, but it also mandates retraining all qualified workers at an interval not to exceed three years. Some companies have adopted a yearly retraining policy, due to the importance of the CSA Z462 electrical safety concepts.

Arc flash analysis training educates electrical professionals about the existence, nature, causes and methods to prevent electrical hazards. Arc flash is a serious hazard with potentially devastating potential injury. Our arc flash analysis training course includes information on arc flash awareness, standards and codes, understanding of arc flash quantities, selection and use of appropriate PPE, reading and following warning signs and labels, methods to reduce risk while working on live exposed parts, arc flash hazard assessment and documentation. This is done to ensure electrical worker safety and meeting the challenges of the arc flash safety requirements can be a difficult task. From arc flash analysis and labeling to personal protective equipment and training.


Who Needs Arc Flash Analysis Training?
Most commercial, institutional, and industrial electrical systems have arc flash hazards. In Canada and the United States, OSHA requires that those systems be individually analyzed and, if hazards exist, labeled to identify the arc flash boundary, the incident energy at the working distance, and the required personal protective equipment (PPE).


Our Arc Flash Analysis Training course teaches arc flash analysis in the following areas:

Arc flash hazard analysis
Arc flash hazard labeling plan
Site review / compliance assessment
Mitigation services
Single-line diagrams
Short circuit and coordination studies
Preventative maintenance
Electrical safety program review / development
Arc Flash Training
Personal protective equipment plan
Arc flash hazard analysis


Arc Flash Hazard Analysis
Canadian Standards Association (CSA) Z462 guidelines require facility owners to perform an arc flash hazard analysis prior to allowing a worker or contractor to perform a task on energized equipment. The arc flash analysis identifies the presence and location of potential hazards and provides recommendations for personal protective equipment (PPE), boundaries for limited, restricted and prohibited approaches, recommendations for flash protection and safe work practices.


The Electricity Forum recommends that arc flash calculations be completed in conjunction with short circuit study calculations and protective device coordination to achieve the most accurate arc flash hazard results. Short circuit and coordination studies verify protective devices and arc hazard ratings, calculate momentary interrupting and relay currents, establish settings for all types of protective devices and coordinate your entire power distribution system to minimize downtime.
