NFPA. 70E. HRC. Hazard Risk Category Levels explained. In it's most basic form HRC level 1 is low risk and HRC 4 is the most dangerous. HRC level is determined by the minimum amount of calories per square centimeter ( ATPV or Cal/cm 2) a treated garment must pass through with a 50% probability of a 2nd or 3rd degree burn occurring, thus the. According to NFPA 70E, arc flash incidents occur five to ten times each day. The occurrence of an arc flash is the most serious fault within a power system. The destructive impacts of an arc flash event can lead to severe injuries of operating personnel, costly damage of the switchgear, and to long outages of the system. Active arc elimination systems can mitigate the above-named consequences. In the NFPA 70E standard, an Arc Flash Study is referred to as an Arc Flash Risk Assessment. NFPA 70E, in turn, refers to IEEE 1584 for when the Incident Energy Method is used. Note that IEEE 1584 uses the term Arc Flash Study. NPFA 70E is not directly enforced from the OSH Act of 1970 in the USA, or the relevant federal regulations
