CO2 Bottle and Safety

I finally got a 5lb. CO2 bottle and a FROG.(the same one George suggested in an archived 
message I read).  Just waiting for a needle valve.

My questions concern safety with this bottle.  It is going to be placed at my fiance's house 
so I want to take all precautions in keeping this bottle from spewing on me.

I have read all the mishaps and what there is about safety in the archives.  I simply want to make sure
I don't so anything stupid and have the bottle erupt on her.

Any safety suggestions would be greatly appreciated.

Thank you,
