If you haven’t been keeping up with the NFPA 70E, Standard for Electrical Safety in the Workplace revision cycle, the 2021 edition was issued June 1, 2020 with an effective date of June 21, 2020. Independent standards development organizations, such as NFPA, and the standards they publish play a major role in protecting the public from injury or death. For those of you who took part in the process whether by submitting inputs and comments, attending the draft meetings, or by being a member of the technical committee, NFPA thanks you for your participation.
For the 2021 edition, Article 110 was revised to incorporate the general requirements for electrical safety-related work programs, practices and procedures from other articles. References to arc-resistant switchgear has been changed to arc-resistant equipment to address the use of other types of arc-resistant equipment. Article 360, Safety-Related Requirements for Capacitors and Annex R, Working with Capacitors were added to address specific electrical safety requirements unique to capacitors. Annex D, Incident Energy and Arc Flash Boundary Calculation Methods was revised to reference IEEE-1584-2018 as a method of calculation. Throughout the standard there are other changes so be sure to check for those that might affect your electrical safety program.
Information regarding not only this new edition but earlier editions, providing input to the next edition and asking a technical question is available on the NFPA 70E web page at www.nfpa.org/70E.
