Is anyone using arc flash warning labels with PPE etc. listed in substations? If so, where are they posted, on the equipment, on the substation gate/fence? - Thanks!

My substation is in a manufacturing plant and everything is deadfront. So I have a label on the doors of all the equipment. If I had an open crib type substation, I would have a large sign made, something like 12"x8" and post it on all entrance gates. For live front equipment typical labelling probably won't work. Could you imagine a 4"x3" label with 1/4" text on the can of regulator and it reads that a 10ft arc flash boundary is required. You'd have to get within 24" just to read it. Plus in a substation you are dealing exclusively with trained personnel. So your policy could say, on the gate, and I think that would cover you.

I think he is talking about an outdoor switchyard.
