NFPA 70E 2015 version, eliminates the commonly used term HRC (Hazard/Risk categories), which described the level of PPE(Personal Protective Equipment), needed for specific tasks in the PPE tables. Instead, the new NFPA 70E use the term “arc rated PPE category,” or simply “PPE level.”
HRCs have become common on clothing, and the levels are still there but will be called PPE categories or PPE levels. The categories remain essentially the same. For example, the current HRC 2, encompassing the range of 8 to 24 cal/cm2, will be PPE level 2, etc.(see tables below).“Hazard/risk category 0″has been removed from the table. Hazards/risk category will now be referred to as “PPE category”. Hazard/risk category 0 was deleted because of the new PPE table only species PPE for work within the arc ash boundary. If there is no arc ash hazard, then no arc flash PPE is required and it is therefore not necessary on the table devoted to PPE.
