The employer is expected to use the best means available to comply with this requirement, and that is done through consensus standards like NFPA 70E. NFPA 70E is about worker safety. The common labeling methods which includethe incident energy require clear procedures so that employees understand that the specified required gear or specified minimum rating, not the incident energy,defines the only permitted PPE rating. Arc Flash PPE Categories. Our understanding of arc flash and arc blast has changed considerably since then. Following that, each method for ensuring safety is considered less effective than the one before it, with the use of PPE as the method of last resort. 1. NFPA 70E states two methods can be used in an arc flash risk assessment to determine appropriate arc flash PPE. Since PPE category is not an incident energy and an incident energy is not a PPE category, these two should never appear on a label together. Use of this table is permitted, meaning it's an optionit can be used, but is not mandatory. These two categories pose the most risk based on the arc rating value and therefore require the most protection and coverage. Several NFPA 70E users ask about using both the incident energy and PPE categoryon a label. FR protective apparel is matched with an arc .
