Where is the definition of an electrically safe work condition found?

The definition of an electrically safe work condition is found in NFPA 70E Article 100. This standard focuses specifically on electrical safety in the workplace and provides guidelines for safe work practices, including how to establish an electrically safe work condition. This includes ensuring that circuits are de-energized, testing for voltage, and implementing lockout/tagout procedures to prevent unintended energization.

The other sources cited do have valuable information related to electrical safety and regulations, but they serve different purposes. IEEE 1100, often referred to as the “Emerald Book,” provides guidance on power quality issues, while the National Electrical Code (NEC) covers the safe installation of electrical wiring and equipment but doesn't specifically define workplace safety conditions. OSHA regulations set overall workplace safety standards but do not delve into the specifics of electrically safe work conditions as defined in NFPA 70E. Therefore, NFPA 70E Article 100 is the most authoritative source for this particular definition.
