Funny you should say this. My neighbor is a crane fixer-upper. He does all kinds of electrical repairs to cranes all sizes and all around the world. Sunday, he was just telling me the highest he ever was up, was 485' in the air. I said, I couldn't get that high unless there were 4 walls around me. He just laughed and then I slowly said...... how did you get up there that high ?? A frickin' helicopter drop you off ?? Nope. Have to shimmy up those things and no harness is used. Hafta shimmy back down, too. He's in his mid forties, has 2 kids and a wife and he does this stuff everyday for a living. Most of the cranes aren't that high, but he never wears a harness. Yesterday, he was down at the Philadelphia Naval Yard, working on a ship's crane. Was up something like 125'. He wants to borrow our bucket truck this weekend to do some stuff around the house. Should I ask him to wear a harness ?? You bet, but I can't force him to, if I'm not home to see it. I'll just leave a note on the dashboard stating all people in bucket must wear safety harness provided in back of truck.
