All of my V-rated tools are clearly labeled with the voltage rating . My Nomex uniform shirt also has a tag on the outside that says FR . V-rated tools have two layers of insulation . If the first layer is compromised , and the second layer shows through , the tool is trashed .
Thanks for posting the youtube video of this segment, I was a little late coming in on this conversation. Do these violations occur very often on TOH? I may have to watch more often with the kids!
