I have an old Green and White Book somewhere, I don't even remember where or how I got them, only that they seemed important at the time along with a copy of the National Electrical Safety Code. I soon found out that I was in the minority even having knowledge of their existence. None of the "Mechanics" (Maint.) I worked with even owned a copy of the NEC.
It gets discouraging after awhile, spouting code that no one including Management really cares about. What's the moral? I don't know, but there were some near-serious accidents and thankfully I was not close by. After the Companys' 'downsizing' to nothing several of these guys tried to get into the Trade but couldn't make it. Last I heard the "Ace" was making Pizza somewhere in Florida.
Do they have an Orange book too? Is that the Hazardous Location Equip?
