Sounds like a good plan to me!.
The idea that I was trying to convey, was that the cover sheets, hide any bits in the panel (or whatever you're working on) that could cause a flash or shock hazard.
Live busbars, terminals and large bits of Earthed metal spring to mind.
Just a small question, We have a test bath at work for the Live Gloves we use for line work and I've used it to test my own gloves, but we have to send the Cover Blankets away for testing in Christchurch.
How do they test a sheet of Neoprene?.
