ST. LOUIS—NFPA 70E Standard for Electrical Safety Requirements for Employee Workplaces requires that before a worker approaches exposed electric conductors or circuit parts that have not been put in an electrically safe work condition, a flash hazard analysis must be performed.

Previously, this has been a difficult and time consuming procedure to meet OSHA requirements that unfortunately might be overlooked in certain situations, creating a serious electrical safety hazard. Bussmann’s easy-to-use on-line program can be quickly accessed by Arc Flash Calculator, connecting to www.Bussmann.com, selecting Electrical Safety from the left-hand navigation bar and choosing Arc Flash Calculator. The calculator is based on the IEEE 1584 Guide For Performing Arc-Flash Calculations (23 September 2002).

This valuable software program quickly outputs the incident energy level and flash protection boundary needed for the flash hazard analysis under specific conditions. Inputs that are necessary are the three-phase bolted short-circuit current available and the overcurrent protective device ampere rating. It is intended to help assist in determining the proper flash protection boundary and level of Personal Protective Equipment (PPE) to help safeguard a worker from severe burns due to an arc flash incident. The information available from this calculator does not address worker protection required to guard against the effects of pressure, shrapnel, molten melt spray, or toxic copper vapor resulting from an arc fault.
