Arc Flash Hazard AnalysisOctober 8–10, 2013 in Madison, Wisconsin

Arc Flashes Pose

Serious Hazards!The National Fire Protection Association(NFPA) defines an arc flash as “a dangerouscondition associated with the release of energy caused by an electric arc.” Five to tenarc flash explosions occur daily in electricalequipment in the United States. Injuriesfrom arc flash events range from minor, tolife threatening, to fatal. An arc flash eventcan, in addition, cause serious equipmentdamage, resulting in an interruption of facilities operation.

An arc flash is essentially an electricalshort circuit through the air. In an arcflash incident, concentrated radiantenergy explodes outward, resulting inpressure waves, a high-intensity flash, anda superheated ball of gas. The potential forphysical injury is extreme.

This proven course will show you how tomitigate arc flash hazards.

Ensure Worker SafetyLearn about new industry standardsestablishing safe practices to protectelectrical workers from the hazards of shock, electrocution, arc flash, and arcblast. These standards include:

• OSHA 29 Code of Federal RegulationsPart 1910, Subpart S

• NFPA 70, National Electrical Code

• NFPA 70E, Standard for Electrical Safety Requirements for Employee Workplaces

• IEEE Standard 1584, Guide forPerforming Arc Flash Hazard

Calculations• NESC 410A3, which required that by 

January 1, 2009, a potential arc exposureassessment shall be performed

At this course you will examine thesestandards, gain an understanding of theirsignificance, and learn how to apply themin your workplace.

Attend and Benefit

This course will assist plant and designengineers responsible for ensuring asafe work environment in industrialelectrical distribution systems. Thisincludes plant, facility, and corporateelectrical engineers dealing with one ormore company distribution systems andconsulting and utility engineers dealingwith clients’ systems. Utility engineers witresponsibilities for NESC compliance willbecome familiarized with arc flash hazardanalysis. Experienced electrical contractorwill also benefit from this course.

There are a number of computer programthat are excellent tools for the analysisof arc flash hazards. We invite providersto send literature and/or demo CDs fordistribution to the class.

Comply with NESC 410A3

The 2012 revision of the NationalElectrical Safety Code includes flameretardant clothing as a requirement. Rule410A3 states, “Effective January 1, 2009, theemployer shall ensure that an assessment isperformed to determine potential exposureto an electric arc for employees who work on or near energized parts or equipment.If the assessment determines a potentialemployee exposure greater than 2 cal/cm2

exists, the employer shall require theemployee to wear clothing or a clothingsystem that has an effective rating at leastequal to the anticipated level of arc energy.”

Section 8 of this course will deal extensively with utility concerns including:

• NESC/OSHA requirements

• Computer simulations

• Case studies

Learn How to Perform ArcFlash CalculationsThe arc flash calculations taught in this

course will enable you to estimate incidentenergy exposure from potential arc sources.A bolted fault creates high current thatflows through the network. Traditional faultstudies are used to select equipment thatcan withstand and interrupt these shortcircuit currents. Arcing faults follow a paththrough a vapor between two conductingmaterials. The arcing fault current issmaller than a bolted fault current, but thepotential for human injury is much greater.

Arc flash calculations follow the NFPA 70E

and IEEE 1584 methods for determiningarc flash hazard distance and incidentexposure energy. These calculationsincorporate short circuit calculations,empirical equations, and protective deviceoperating times.

What Students Say…

“This has been a very informative

and eye-opening experience.”

“I feel much more confident

 that I can move forward with

implementation at work.”

“I came to hear from experts

about how to perform arc flash

studies and what to be aware of.

 The instructors were experts and

provided the information I was

looking for.”

“We have relied on outside

consultants over the years.

 This info provides a very good

overview of what others

are doing, thinking, and

interpreting.”

“Great insight from a full

spectrum of presenters. Good

interaction between students

and presenters.”

“I was looking for a good

introduction to the topic, from

both the commercial/industrial

and utility perspective. The

course exceeded my expectations.”
