![]() There is no magic in the categories but at the time most garments and almost NO systems were rated so we developed this idea with the NFPA 70E Table committee to offer protection and ease of selecting PPE. The idea was that every single layer system on the market in 1998-1999 (or so because this entered NFPA 70E in 2000) would meet HRC/ARC/CAT 1.Įvery two layer system would meet HRC/ARC/CAT 2Įvery Three layer system would meet HRC/ARC/CAT 3Īnd a two layer with a flash suit would meet HRC/ARC/CAT 4. We did tweak the categories based on my data but the idea was Tom’s. Since I tested for many companies and he had only DuPont data, I validated his findings. He sent me his table and a list of the PPE he had tested which met the four categories. The idea of the categories was developed by Dr. HRC 2 (Now PPE Category 2) is PPE which has a rating of 8-24.9 cal/cm² BUT the category hazard from the tables is expected to deliver no greater than 8 cal/cm². That was a mistake made my many training companies and a few less knowledgeable PPE manufacturers.
