Protecting workers’ lives is a priority. If a serious incident occurs, the emotional and financial effects can be devastating. For most countries, including the United States, electrical safety is mandated and regulated by the law. OSHA 1910.132 requires employers to assess the workplace to determine if hazards are or are likely to be present. OSHA references the National Electrical Code (NEC), NFPA 70E – Standard for Electrical Safety in the Workplace, and IEEE standards for compliance. Additionally, these standards, as well as the National Electrical Safety Code (NESC), which is specifically enforced for electric utilities, require an arc flash assessment to be performed. IEEE 1584 – Guide for Performing Arc Flash Hazard Calculations, provides a procedure for performing the arc flash hazard/incident energy calculations.
