I have a customer that has a 1" copper line that provides liquid oxygen to to a machine. He wants me to cut in a ball vale of course I know I'll have to silver solder it. But I am unfamiliar with liquid oxygen other than the fact that it is highly cbustable. There are unions on line so My question is if I bust union apart is it safe to solder after it air out for a few minutes? Thanks for any help
