2018 updated versions of NFPA 70E and its Canadian counterpart CSA Z462, have been released. Here are some of the major changes.
Hierarchy of Risk Control Methods —The hierarchy of risk control methods is now part of the mandatory text with an emphasis on identifying risks and mitigating those risks BEFORE a job starts. The standards now explicitly state that the priority must be the elimination of the hazard; each method of control that follows is considered less effective than the one before it.
Risk Assessment Procedure — Completing a Risk Assessment Procedure for every energized electrical work task is mandatory and shall be documented as a requirement in your company’s Electrical Safety Program. The risk assessment procedure now specifically requires you to address human error and its negative consequences on people, processes, work environments, and equipment.
Establishing an Electrically Safe Work Condition (ESWC) — Although there are no major changes to these requirements, the information in the respective sections (NFPA) and clauses (CSA) has been completely restructured to logically step you through how to set up a program.
