NFPA 70E Hazard Risk Category Levels (HRC)

NFPA 70E is a safety standard that denotes Hazard Risk Categories (HRC) based upon an array of occupational duties. An HRC level is determined by the minimum amount of calories per square centimeter (ATPV or Cal/cm2). There exists five risk levels which range from 0 to 4. Level 0 is little to no risk whereas, level 4 is extreme risk. The following chart illustrates the five HRC levels with corresponding clothing, layer requirements and minimum arc ratings.
