Does anyone have an image with only the limited and restricted approach boundaries along with the arc flash boundary shown? Since the NFPA has discontinued use of the prohibited approach boundary definition I would like to bring my arc flash hazard reports up to date with the terminology in the standards. In the past we've used an image that includes the prohibited approach boundary but if it is passe then I'd prefer to avoid using it.

Thanks

From what I understand reading the new 2015 standard a label can only list the cal/cm2 that was determined by performing an arc flash hazard assessment. The only time you can list both the incident energy and the PPE level is if the facility has a site specific policy for PPE level that they must use. If I am way off base on my understanding please let me know. I have attached a proto type label that we plan to use.

The revised 70E language states:


•  Either the available incident energy with the corresponding working distance or the arc flash PPE category in Table 130.7(C)(15)(A)(b) or Table 130.7(C)(15)(B) shall be listed but not both.


There is nothing in new NFPA 70E that prohibits using the term "PPE Level". As long as you don't call it "PPE Category" there should be nothing preventing you from doing so. Remember that not that long ago people were told not to mix HRC with incident energy. So they began to call it 1, 2, 3 and 4 PPE categories to get away from the term HRC. This time 70E kinda claimed ownership for the term "PPE category" that people moved to, and say you can't use that term with incident energy. I guess "PPE Level" will be the next term 70E prohibits using along with incident energy.

Also, the NFPA Handbook shows a sample label with fields to be filled in for "Available Incident Energy" and "Level of PPE" while just half a page earlier states that "available incident energy" cannot be included with the "PPE category" in table 130.7(C)15(A)(b).
