I too have been a member of the IBEW since 99. As far as lockout Tagout, it all depended on the job, industrial it always happens, commercial it rarely happens. Local 58 is saturated with wiremen and the competition for work is fierce so you do what you have to do to be better and faster than the next guy and a lot of the time that involves working on live gear. It never bothered me to work hot (nothing macho about it) I always thought it brought some excitement to an otherwise boring day the main thing to remember is to stay afraid and you'll be okay.
As a wiremen I did really well I was the youngest Forman for the 2nd largest company in Michigan and on my last job I made the company an 18% profit however I hated the work, didn't care for most of the people I worked for and I detested the competition so I left the trade. Now I'm happier than a pig in mud as a barber.
If you love electrical work I would suggest taking classes to be a splicer, I did and it was the only part of the trade I really loved and there are lots of benefits to it. Best of luck to you!
Sorry for getting off topic there.
