[TheForge] old propane tanks

[Dave Mudge]

We regularly repair aluminum diesel fuel tanks and aluminum hydraulic
tanks at work. We usually wash them out with water then fill them with
argon or C-25 (75% argon / 25% co-2) . That displaces any burnable
fumes and any oxygen. I would do the same if I was going to cut a
propane tank.
On the other hand you could (perhaps) crush and sell the propane tanks
to the scrap yard then use that money to buy some less dangerous tanks
like used freon tanks.
