In the contracting world that I came from, we did a lot of things that were really not safe, but you did what you had to do to get the job done. I was young and dumb at the time, and invincible in my mind. Climbed off of a scaffold 60 feet up to fish a wire once, stood on a 2x4 on top of a climbing stair to very awkwardly install a conduit too. Probably inhaled a lifetime worth of asbestos and insulation along the way. But hey, it paid off and I'm now in a much better place large in part due to my field experience.
