The instructor, Jim Phillips is not just another trainer reading a script. Jim’s training is based on his insider’s view from holding many leadership positions for the development of various electrical safety standards coupled with his arc flash testing experience and broad electrical power background. This provides him a unique perspective from the inside – a perspective he loves sharing with others. When asked questions about some topics, his explanations often run along the line of “Well, here’s what happened in the lab when we blew it up…”
Watch the video as Jim provides a one hour overview of the major changes to the 2021 Edition of NFPA 70E.
Here is a sample of Jim’s involvement.
♦ Vice Chair – IEEE 1584 – IEEE Guide for Performing Arc Flash Calculations
♦ Technical Committee Member – NFPA 70E Committee
♦ International Chair – Geneva, Switzerland based, IEC TC78 Live Working – 40+ global standards including many for arc flash.
♦ IEEE/NFPA Arc Flash Collaborative Research Project – Member of the Steering Committee
♦ Author of Complete Guide to Performing Arc Flash Hazard Calculation Studies

Watch Jim explain why electrical equipment’s doors are not considered as protection from an arc flash. One of his arc flash tests illustrates how doors can blow open during an arc flash.
Why is NFPA 70E Such an Important Standard?
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. NFPA 70E is used to define the specific details and requirements.
