NFPA 70E 2015 (PPE category change from 2012 standard). What happen to PPE Category 1 and 2?
Question:
There are four different categories in PPE Table such as 0, 3, 4 and DANGER.
What happen to PPE Category 1 and 2?
And what is difference between PPE category 3 and 4?
It looks those are the same Protection.
Solution:
In PTW, we are performing Incident Energy Analysis so we can’t use Table 130.7(C)(16). Please refer to NFPA 70E 2015 130.5(C). NFPA 70E 2015 recommends using Table H.3(b) when performing Incident Energy Analysis which is our default.
We are moving away with terms like Category and Level and just using incident energy like in Table H.3(b). So now, it will not show Category or Level numbers in PTW by default.
from the NFPA 70E 2015 which only utilize 3 levels (<=1.2cal, 1.2 - 12cal, >12cal) as shown below.
