While I'd like to say no problem I know how much training these guys endure to learn all of the safety procedures down cold 10 times over. Their safety protocol makes training for a space flight look like taking a ride in an elevator. I've been out to the tip of the boom on tower cranes to clear fouled cables and do other repairs which were probably higher off the ground than those guys the difference there was there was no 500K volts to worry about.
