I am using SKM software with 1EEE 1584 for an incident energy analysis.
Customer want to show the PPE Level on the arc flash label and not the arc flash energy on the label which is Ok.
But the customer wants to show the PPE (PPE Level 0&1,2,3,5) from the NFPA 70E-2021 table 130.7 c (15)(a) on the label which is the PPE Equipment Category Method and not the SKM PPE Level from the software program (Level 0,3,4,dangerous).
I know that you can label site specific PPE on a label but it seems that this is mixing apples and oranges since I am doing an incident energy analysis?
thanks Jimmy

What your customer wants isn't the correct application of the 70E guidance. The table you refer to is only specific to using the table method. Table 130.5 (G) is the PPE table to be used when an incident energy analysis has been performed. SKM bases its PPE table on 130.5(G) in the 70E.

(not a formal interpretation)
Site specific is open to interpretation. If an owner wants to adopt their own values, they can but it needs conveyed to the workers and everyone involved. So 1, 2, 3, 4 is OK if it is "site specific' Basically I view this as a loophole stemming back to resolving a 2009 NFPA 70E issue when NFPA 70E began with prohibiting including HRC (since changed to PPE category) and incident energy an the label together. There was quite a protracted debate (I as part of it) regarding all this and "site specific" was the compromise.

My preference these days is to list the arc rating instead. People really just want to know what to wear.

I have a video (free) that includes a simplified labeling strategy (Module 7 in the series) that satisfies NFPA 70E 130.5(H). Many companies have been adopting this approach.
