Not many of us remember riding the ball up and down to whatever elevation or platform you were hanging iron on that day. I cuss OSHA just like everyone else but in the end they did stop those kind of stunts. But it sure was faster for us, at the time we just thought we were being efficient! Once I became a crane operator many moons later I would always think of those days while we were doing the obligatory rescue exercise for tank extraction. They would harness a guy up and I got to fly him around a bit. The super always got the new guy who was very pale at the thought, explaining it was part of safety protocol. It actually is. Anyway, He would get him hitched to the little ball and give me the thumbs up and I would swoop him up and around! Super would then get on radio and offer me incentives if the guy puked!
