Hi all, I want to use arc flash PPE hazard risk category 3 and am planning to buy the HRC3 kit from salisbury with a rating of 31cal/cm2. Do I still need to wear a FR coverall underneath with a rating of 4cal/cm2? |

NM = Non melting a.k.a. cotton or something similar. No polys that can melt or make things worse. |
