32、 the Workplace 2018 Edition This edition of NFPA 70E , Standard for Electrical Safety in the Workplace , was prepared by the Technical Committee on Electrical Safety in the Workplace and released by the Correlating Committee on National Electrical Code . It was issued by the Standards Council on Aug
33、ust 1, 2017, with an effective date of August 21, 2017, and supersedes all previous editions. This document has been amended by one or more Tentative Interim Amendments (TIAs) and/or Errata. See “Codes Part II, Safety- Related Work Practices; Part III, Safety-Related Maintenance Requirements; and Pa
34、rt IV, SafetyELECTRICAL SAFETY IN THE WORKPLACE 2018 Edition Requirements for Special Equipment. It was not considered essential for all of the parts to be completed before the standard was published and made available. Each part was recognized as being an important aspect of electrical safety in th
35、e workplace, but the parts were sufciently independent of each other to permit their separate publication. The rst edition of NFPA 70E, Standard for Electrical Safety Requirements for Employee Workplaces, was published in 1979 and included only Part I, Installation Safety Requirements. The second ed
36、ition published in 1981 included a new Part II, Safety-Related Work Practices. In 1983, the third edition added a new Part III, Safety-Related Maintenance Requirements. In 1988, the fourth edition was published with only minor revisions. The 1995 edition included major revisions to Part I to conform
37、 to the 1993 edition of the NEC. The concepts of “limits of approach“ and establishment of an “arc“ were introduced in Part II. In 2000, the sixth edition included an update of Part I to the 1999 NEC, as well as a new Part IV, Safety Requirements for Special Equipment. Part II continued to focus on
38、establishing ash protection boundaries and the use of personal protective equipment (PPE). Also, charts were added to Part II to assist in applying appropriate protective clothing and personal protective equipment for common tasks. The 2004 edition presented several signicant changes. The major chan
39、ges emphasized safe work practices. Clarity and usability of the document were also enhanced. The title was changed to Standard for Electrical Safety in the Workplace. The document was reformatted to comply with the National Electrical Code Style Manual. The existing parts were renamed as chapters a
40、nd were reorganized with the safety-related work practices relocated to the front of the document to highlight the emphasis, followed by safety-related maintenance requirements, safety requirements for special equipment, and safety-related installation requirements. The chapter on safety-related wor
41、k practices also was reorganized to emphasize that working on live parts is the last alternative work practice. An energized electrical work permit and related requirements were incorporated into the document. This standard is compatible with the NEC but is not intended to be used, nor can it be use
42、d, in lieu of the NEC. Chapter 4, Specic Purpose Equipment and Installations, was intended to serve a very specic need of OSHA. It was not intended to be applied as a design, installation, modication, or construction standard for an electrical installation or system. Its content was intentionally li
43、mited in comparison to the NEC in order to apply to an electrical installation or a system as part of an employees workplace. Chapter 4 was updated to correlate with the 2002 edition of the NEC, but requirements not directly associated with employee safety were not included. Omission of NEC requirem
44、ents did not affect the NEC, nor were omitted requirements considered as unimportant. They are essential to the NEC and its intended application that is, its use by those who design, install, and inspect electrical installations. NFPA 70E, on the other hand, is intended for use by employers, employe
45、es, and OSHA. Requirements were upgraded throughout the 2009 edition. Chapter 4 was deleted because it was a duplicate of NEC installation requirements. Article 350 was added for R&D facilities. Other changes included signicant revisions to Annex D, Annex F, and Annex J and the addition of Annex M,
46、Annex N, and Annex O. The 2012 edition marked another waypoint as this standard continued to evolve to meet the electrical safety needs of employers and employees. New research, new technology, and technical input from users provided the foundation for new and revised requirements that addressed the
47、 electrical hazards encountered by employees in current workplaces. Expanded or claried requirements, inclusion of technical material not previously covered, and removal of requirements related to the safe installation of electrical equipment rather than being safe electrical work practices were som
48、e of the major actions undertaken during the revision cycle. In addition, requirements covering the separate but directly related concepts of hazard identication and risk assessment were revised to clarify the concepts. A signicant revision to Annex F provided extensive coverage of this topic to ass
49、ist users with implementing effective hazard identication and risk assessment procedures. Annex P on aligning NFPA 70E implementation with occupational health and safety management standards was added. The majority of changes occurred in Chapter 1. Article 105, Application of Safety-Related Work Practices, and a requirement for hearing protection when working within an arc ash boundary were added, as were work practice requirements on the use of GFCIs to protect employees. Clarication was made that Article 130 applies whether incident energy ana
