what's the fuss?
I have kept blue rings before, and contrary to popular belief, mine never attempted to leap out of the tank and attack my face at all! Seriously though, I keep all my venomous animals (snakes, etc) in one room of my house, which is locked...I am not worried about being envenomated myself, just worried about a neighbor or a friend at a party getting too curious. That said, I really don't use any special precautions in dealing with blue rings, other than the obvious: don't put your hand in the tank for any reason. Every keeper I know who has been injured by a venomous animal has disobeyed this rule. You should use a sumped system, so all filter changes, etc occur OUTSIDE the tank. Tank cleaning can be done with sticks and tools. A lid that will keep in a vulgaris will keep in a blue ring too! The easiest setup would be an established natural reef... lots of rock and a bit of calurpa, and you are set! Good luck! Send in some pics when you get one!
