IEEE Cincinnati January 2025 Meeting

An arc-flash hazard analysis, also known as an arc flash study is a risk assessment that evaluates the likelihood of an arc flash incident and how to protect people from the resulting hazards: – What it does – Determines the potential energy of an arc flash, the likelihood of injury, and the appropriate PPE to protect workers – Why it’s important – Helps ensure compliance with arc flash codes and standards, and facilitates safe work conditions – Who requires it – OSHA enforces employers are required to ensure their workers understand and can protect themselves from arc flash risks – How often it’s required – NFPA 70E requires arc flash studies to be updated every 5 years or as needed per power system modifications An arc flash hazard analysis typically includes the following components: – Field survey – Data collection of the power distribution system – Single-line diagram – Produce a power distribution schematic – Short-circuit analysis – Determines the fault current that would flow to each piece of equipment in the event of a short circuit – Incident energy analysis – Determines the potential arc flash energy present in each piece of equipment per IEEE 1584 – Protective device coordination – Compares the fault current to the interrupting capacity of main circuit breakers or fuses – Reports and recommendations – Includes label installation with hazard and PPE guidance Speaker(s): Dave Hernandez, March First Brewing & Distilling, 7885 E Kemper Rd, Cincinnati, Ohio, United States, 45249
