Chev, please don't take this the wrong way but your posts show some misunderstanding of the requirements and basis of PPE. If you are the ESWP trainer at your facility you really need to get some "train the trainer" training, I used to offer these in Michigan but no longer do that stuff but I can recommend some people if you like. I understand the difficult position you are in, seen the same thing many times.
The other guys addressed your questions already, keep in mind there are 2 types of PPE, shock and arc flash. Shock PPE, such as rubber gloves will be dependant on voltages, but arc flash PPE has little to do with voltages. If your facility used the tables there should be different HRC's for doors open and closed and different tasks, which makes it all confusing for the operator. The limitations of the tables changed with the 2009 70E so that should be looked at and many of the HRC's from the task tables changed also.
Your best bet it to get some good compliance training, sounds like your facility needs to start from square 1. Again, I really don't want this to come off the wrong way and will be happy to help, as will many others here.
