Workers commented that there was no method for selecting all the PPE required when using the incident energy analysis method, because Table H.3(b) was in Annex H and anything in the annexes is not considered part of the standard. In the 2018 70E the table was modified to eliminate any clothing or PPE under 1.2 cal/cm2, because it only deals with arc-rated clothing and other PPE. NFPA 70E is the major industrial standard for safe electrical work in the United States. Categories 1 and 2 are both listed as single layer. Incident energy is not a good measure of the pressure wave that might be created by an arc event. Click to reveal learn more 2. PPE Category 3: Minimum Arc Rating 25 cal/cm2PPE Category 3 and 4 require additional layers of PPE. Chapter 1 is divided into ?
