Trumpy, My folks first rule is: If you feel or think it is unsafe (for whatever reason), you don't do it. Any employee has the right to refuse and I will back them up. My philosophy is that there is nothing we do that is worth the loss of life or injury of any kind. And I re-inforce this on them quite often. In thirteen years I had one emplyee injured, cut her finger on the jacket of a water heater.
