Hi Jesse

    I wrote the original post that you were responding to.... I
    personally use the one pound disposable bottles that you are
    referring to with my Little Torch. 

    The small 1 pound bottles disposable propane bottles are also
    equipped with small pressure relief valves similar to the ones found
    on the larger BBQ sized bottles.  But, since the disposable bottles
    are filled by the manufacturer under controlled conditions, the
    relief valve should never ever open when exposed to the typical
    temperatures found in your home basement studio. The only time that
    I would expect these relief valves to open is if the bottles are
    exposed to fire or a direct torch flame.  As long as they are
    handled in a careful manner, these propane bottles are perfectly
    safe to use in your home.
