As it was explained to me, if an indivdual could use a conductive item and is able to make contact with energized parts, that means that there is hazard present. Such as a paper clip, a metal knife blade, keys, etc. Therefore we must pursue avenues to minimize or eliminate the "hazard". As I understand, this means de-energizing the system or require tools to gain access to the energized parts.
While I concede someone has to work at it to harm themselves, where do we draw the line? If my interpretation of this is correct, then ALL unused outlets must be de-energized. That will certainly cause problems for anyone who needs to find the correct breaker to turn on a de-energized outlet to plug in a vacuum cleaner, trouble light, or battery charger for their computer. How about circuits where some of the outlets are used and the rest of them empty?
My philosophy is that people have to have some basic sense. If they are that much of a hazard that we have to protect them from themselves, then they should not be allowed to be in the work area, be allowed to use fire, or drive a motorized vehicle. Typically if a person is not trained to not stick objects into electrical bits, we hire a sitter to keep them out of trouble.
