Welcome, zorinlynx;
It's extremely that you get proper training before even THINKING of going into a medium of high voltage situation. You will not get a second chance; if you are uncomfortable, don't go in the area. If your boss forces the issue, consider quitting right there. No responsible foreman would expect an untrained person to risk his life when they aren't ready to work there. I used to give tours in-house and let folks know that the guests who WEREN'T nervous about the 15kV equipment needed to wait outside. Too many people have been hurt or killed leaning on or backing into something. Remember that you need to respect electricity; it won't cut you any slack. If you get close enough (and the distance can change with the weather) it will bite you.
Also, if you work with a buddy and the flash gets you both, who's going to call for help? Always have someone outside of the 'danger area' watching your back.
Simple rules...never work alone, keep your hands in your pocket when not working, don't touch anything and don't approach unless someone standing closer to the equipment tells you to.
