Arc Flash NFPA 70E Online Training Course

Course Overview

2018 Changes:

We changed a couple of events in chapter 5 due to recent changes to the NFPA 70E guidelines for electrical safety. 

The following was changed:

To determine where this boundary should be, you calculate at what distance from the equipment the "incident energy" of an arc flash would equal 1.2 calories of heat per square centimeter. ("1.2 calories per square centimeter" is the "heat value" that will cause a second-degree burn unprotected skin.)

This "second-degree burn distance" is where the Arc Flash Boundary will be set up.


Electricity is so common in our homes and workplaces that we normally don't think twice about using it. But electricity kills and injures thousands of people every year, so it's important to understand its hazards and know how to avoid them. 


Electricity poses two major hazards to people who work with it. The most intense is arc flash, a violent release of electrical energy that causes severe injuries and fatalities. The second is shock, which can cause burns, internal injuries, cardiac arrest and even be fatal. 

Atlantic Training's new training on Arc Flash focuses on what arc flash is, its hazards and how employees can avoid it on the job. The program provides practical procedures employees can use to protect themselves from electric shock, as well. 

Topics covered in these products include:

  • Shock and how to avoid it.
  • What is arc flash?
  • Personal protective equipment.
  • Creating an electrically safe condition.
  • Avoiding arc flash situations.
  • …and more.
