• Arc flash and shock hazards have existed as long as electricity has. NFPA 70E has contained valuable information to protect against shock, i.e. rubber insulating gloves. It was only in the last 15 years however, that we learned how to accurately calculate an arc flash. The calculations became easier with the advancement of software and computers. Now that we understand how to calculate a shock, let’s protect against it.
  • Better studies and calculations have been done to allow calculations of potential arc energies.
  • NFPA 70E is not only the recognized standard but it is now becoming more general knowledge. As more people learn the value of this standard, more will be trained.
