With 2015 and 2018 editions of NFPA 70E, a major shift occurred in how stakeholders evaluate electrical risk. The National Fire Protection Association’s 2018 NFPA 70E: Standard for Electrical Safety in the Workplace, the latest edition of the voluntary consensus standard, addresses workplace electrical safety and includes guidance for performing risk assessments of arc flash, shock, and electrical hazards exposures.

The 2018 edition carries over several significant changes over previous editions. Where an arc flash, shock, or electrical “hazard analysis” was required before, now a “risk assessment” is required. Further, the standard has expanded the “risk assessment procedure” to include the requirement of hazard identification, assessment of risks, and the implementation of risk controls according to hierarchy of risk control methods specified in ANSI/ASSP Z10.0. The addition of the Informative Annex F, Risk Assessment Procedure, provides information regarding the process steps, risk estimation, risk reduction, and risk evaluation in alignment with ANSI/ASSP/ISO 31000. This shift from “hazard analysis” to “risk assessment” reflects a change in awareness about the potential for failure, moving from a hazard‐based to a risk‐based focus. In support of this shift, new definitions for hazard, hazardous, risk, and risk assessment are now included.
