So, I'm trying to figure out when to have our folks wear PPE according to NFPA 70E. For example, if one of my folks (Qualified) is throwing a 480 volt switch on a welder plug; is that interacting or what about throwing a 240 volt switch for compressor? We understand the easy part; if the doors were opened on either disconnect and they were energized, it would absolutely be interacting and therefore proper PPE would be required. What about if the disconnect box is closed? Is the fact the box is closed enough to say PPE is not needed? I'm trying to protect our employees, but between the expense and employees balking at "wearing PPE for everything", I'm frustrated. I don't care what the cost is, if I need to protect my employees. By the same token, I don't want to throw money out the window and I don't want frustrated employees. Our employees too, believe in wearing the PPE, but they question what interaction really is.
