We are building / designing / testing a machine. The machine uses what I think are touch safe terminals. All energized parts >60V are insulated or behind suitable insulators. I am standing there, inside a roped off area, more than 40 inches between the rope barrier and the open energized control panel. The safety consultant was concerned that the panel should be shut whenever the machine is energized. We have been running the machine for debug purposes with the panels left open. People inside the roped off area are aware of potential hazards and are properly trained.
