Although the duty to provide electrical safety in the workplace can be traced to the 1970 Occupational Safety and Health Act, updates and continual revisions to OSHA, National Electrical Safety Code (NESC) and the 2015 Edition of the National Fire Protection Institute (NFPA) 70E represent the basis for requirement for Arc Flash Risk Assessment (formerly a Hazard Analysis) and protective clothing and equipment. Updated Incident Energy Levels should be determined based on any system revisions and 2015 NFPA 70E requirements.
