Table 130.7(C)(15)(a) is used to determine whether arc flash PPE is required.

• A. True
• B. False
• C. Not specified
• D. Depends on category

Answer: (B)

Arc flash PPE is chosen after assessing the hazard, not used to decide whether PPE is required in the first place. The table 130.7(C)(15)(a) translates the incident energy (cal/cm^2) at a given working distance into the minimum PPE category you should wear. In other words, once you know there is an arc flash hazard and you have the energy level from your hazard analysis, the table tells you which specific PPE to use. It’s a selection aid, not a decision tool for whether PPE is needed at all. If the hazard analysis shows an energy level that requires protection, you then consult the table to determine the appropriate PPE.
