LOL, I've had scorpions and tarantula's far longer than snakes! As long as you are careful there is nothing to be afraid of. Low maintenance pets!
The important thing to remember about Pandinus imperator is that it is a rainforest species and needs to have high humidity. Use potting soil or some other substrate that holds water well. I would recommend it be 3-6 inches deep or so. Keep the temps about 75 or so, provide a water dish and a hide and you will be good to go.
