Q: If you were working inside of a panel with high and low voltage, would it be allowable to have a shield installed to separate the two so that you could work on the low voltage equipment without needing to put on all of the arc flash and shock PPE? A: Electrical hazards are made...

Did something about the balaclava change recently in NFPA 70E®2018? Recently I completed an arc flash engineering study (part of an arc flash risk assessment) and then labeled the electrical equipment. I was asked by the electrical engineer at the plant as to whether the arc flash engineering study was based on NFPA 70E® –...

Q: Do we need arc rated protection or shock protection (like rubber gloves or arc rated gloves) when switching inside industrial panelboards similar to the ones we have at home (e.g. 120V)? A:  It really depends on the individual situation. What are the most common operations on 120V panelboards (fed from transformers that are generally...

large, mostly empty warehouse
Warehouses, silos, and logistic operations are exposed to the electrical hazards of arc flash and electrical shock. In fact, unique risks are present when the electrical utility bill is one of the smaller budget items, as is the case in warehouses, silos, and logistic operations.  This, together with the rather infrequent performances of electrical operations,...
