    hi, i'm assuming you're refering to a small b tank not a big honker
    industrial welding bottle in all these answers 

    1. not really there is fire hazard but with the tank off it should
    be fine in most conditions. 

    2. i've been using acetelene for 35 + years both in jewelery and
    plumbing. i routinely leave the tank outside in my truck. keep it
    upright to keep the gas stable. 3.shutting off the main valve key and
    bleeding is fine. the regulator knob doesn't need to be touched if
    you're happy with the gas flow. the regulator's job is to regulate
    the flow of gas to your torch head. if you want a bigger flame add
    more pressure as read on the valve and adjust up or down at the
    torch head . for less pressure do the opposite. 

    4.you'll notice as the tank gets empty the flame intensity will wan.
    as you approach empty you'll also get some popping from the acetone
    mixing in . i usually replace the tank when the flame velocity gets
    weak , mostly cause i'm fussy about my flame being consistant and
    not having a popper trash a delicate joint. 

    5. it really depends on what's burning . water is usually a bad
    choice except for wood or paper. electrical fire and any burnable
    liquids come to mind as really bad with water .using water on the
    first could kill you and on the second it'll just spread the fire
    out. get a couple of really good LARGE fire extinguishers suitable
    for all types of fires. put them in easy to access locations and you
    should be fine . 

just my 2 pennies   dave
