You can't have an arc rating without the material being flame resistant. Sometimes this boundary is the furthest one from the exposed equipment, other times the limited approach boundary is the furthest out. Arc flash (often called a flashover) is a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system. LLT ARC - ATPV 55 CAL/cm Jacket How often have you heard someone say, "I need an 8 cal shirt." Or, "My clothing needs a minimum of an 8 cal rating." Or even, "My blast suit is 40 calories." These common statements are the reason the NFPA 70E committee changed their terminology from hazard risk category (HRC) levels to personal protection equipment (PPE) levels in the 2015 revision of this standard. What about arc flash suits for the high incident energy levels. The results are often violent and when a human is in close proximity to the arc flash, serious injury or .
