[TheForge] old propane tanks

[Paul Novorolsky]

Just for the record: from what I've read, freon decomposes to phosgene 
at high temps. So while freon tanks are less likely to go boom, they 
aren't completely "safe" either. So they too need to be handled 
appropriately.

Information can be found on many welding safety sites.
