Personnel safety is the most important concern in the workplace.The NFPA 70E sets standards for electrical safety in the work environment and keep workers safe while working on or around electrically energized equipment. IEEE 1584 sets the industry standard for evaluating the arc flash hazards in a power distribution system and its equipment. 29CFR1910 subparts R and S tie these standards and governmental regulations for electrical safety together. OSHA mandates regarding electrical safety in the workplace specifically require employer assessment of generally recognized hazards in the workplace, and provisions for protecting the employee from those hazards.
