I don't have the costs on that. There are 2 different types of fittings - flammable and non-flammable (flammable screws on backwards and has notches and some other differences). I think picking up a non-flammable tank might be nice, but we would need to find a corner to chain it up to. Even non-flammable tanks are pressurized and can become projectiles if knocked down and the (soft brass) valves get knocked off, as could happen in an earthquake.<div>

</div>If it's possible to revise the date, would the earlier weekend work<br>
better? 2/13 and 2/14 are also the weekend of BIL, which might be a<br>
conflict for some.<br>

</div>Dumb question: are tanks at all gas-specific, or it it just fittings<br>
that care about seal materials and stuff? If we buy one for NB, will<br>
it be usable for any future project that has gas storage needs? And<br>
how much would it cost?<br>
