Put up Arc flash labels on switchboard(s) with PPE requirements 3. ![]() Inform workers of the risk of the risks 2. Related shock-hazard approach boundaries include the limited and restricted approach boundaries, which refer to closer, more-hazardous distances from electrical equipment that require greater safety precautions in order to operate within. Complete an Arc flash study to determine safe working boundaries and PPE 1. Other standards require all equipment that necessitates an arc-flash boundary to be clearly labeled with information stating what that boundary is, thus enabling a quick understanding of the safe working distance by anyone near the equipment. 3: IEEE 1584-2002, IEEE Guide for Performing Arc Flash Hazard Calculations, is one of the available methods that provides guidance in determining arcing current. Both solutions also provide specific obligations for the PPE that must be used by individuals working closer to the equipment than the arc-flash boundary. within an arc-flash boundary as defined in NFPA 70E-2018, Standard for Electrical Safety in the Workplace. In lieu of calculating the point at which incident energy will equal 1.2 cal/cm 2, the standard also provides a table-based solution for determining an arc-flash boundary based on the properties of the electrical equipment under consideration. The NFPA prescribes specific calculations for determining the arc-flash boundary under Annex D of this standard. It is an OSHA-recognized consensus standard therefore, the arc-flash boundary has legal weight as a boundary that must be observed in workplaces in order for employers to meet their general duty obligations for workplace safety. The arc-flash boundary concept is defined by the National Fire Protection Association’s 70E standard.
