Carbon monoxide should not burn and it'll delude the propane.
This is just my method and opinion of how to deal with them but gas tends to permeate the metal of the container it is stored in and heat expands and releases it.
As far as exhaust goes It may work fine coming from a warm well tuned engine with a catalytic converter but is noxious as hell no matter what
I've seen a lot of people get away with cutting and welding on them without incident but I just won't do it.
I've seen enough tanks blown apart to convince me that I don't wanna be anywhere near one going off.
