Hi Francois,
Installing glass is not difficult or dangerous, nor do you need any special tools other than gloves and a good back. The edges are usually rounded from the factory (inhibits large chip-outs from occurring around the edges) and are safe to handle.
A couple things about tempered glass sheets: they hate any single point pressure or binding when mounted. Make sure the seal surface is smooth and free of protrusions such as nails, staples ect. The glass needs to lie flat and not bind anywhere around the edges, otherwise it will shatter when you apply the pressure from the outer stops.
The other important thing to remember when handling large sheets is that the glass needs to stay pretty much vertical all of the time. If it goes too horizontal without proper support, it will fold in on itself and crumble.
A 4'X8'X1/2" sheet of glass will weigh in at a bit over 200 pounds, and I think if you've never done this before, you should have the glazier do it. Have them come out and measure it too, so they're responsible for any mistakes.
You are going to do most of work anyway; all of the inner stops should be in place, and the outer stops cut with seals in place and ready to install. This should be the last of the major mechanical tasks, and everything should be vacuumed and cleaned the day before installation. The air needs to settle and be dust free. Shutting off the air cond wouldn't hurt either.
When the glass is positioned on the floor in front of the opening, give it a good cleaning with windex and lint-free towels. Have a buddy with a light shine it at an angle while you clean. Take your time doing this, and don't let the installers rush you. When you're absolutely satisfied with it, have them lift the glass into place. Make sure there is no binding and that it sits flat against the inner seal. Then you can install the outer stops. After the first pane is in, you have a second chance to clean it from the inside if you missed something or a palm hit it. The second one you won't, obviously, so take your time with it.
