The NFPA has identified the various FR hazardous risk category levels, which range from PPE 1 (which is low risk and requires AR clothing with a minimum arc rating of 4), up to PPE 4 (which is high risk and requires AR clothing with a minimum arc rating of 40). Each level, 1-4, is rated at a certain amount of flame resistance measured in cal/cm2.
