What types of PPE does an OSHA Compliance Officer wear in the USA when making an inspection of an indoor substation?
Darned good point, mate.
I would imagine that Safety Glasses or a visor would come into play, where that Inspector would be looking to remove the Dead-Front of the Panel.
A small question Joe, should it be any different to a worker accessing a panel, should that panel be Live?.
As in, should a Fault-Current calculation take place before that Dead front is opened, to decide what type of PPE shall be required?
To also add, I would not
open any panel wearing less than Class 1 Insulated Gloves and Outers and my over-alls sleeves rolled fully down.
BTW, a Hot-stick (or a Shot-gun stick) is also classed as PPE these days too.
What sort of voltage would you be dealing with, with an Indoor Sub-station?.
Only Sub-station's I've ever dealt with are Outdoor ones.
