Hello all, a very basic beginnings question here, I don’t want to mess up anything. I was wondering what the proper procedure is for bleeding the air out of a nitrox dedicated tank. Is there anything special that needs to be done for bleeding out Nitrox? I know to leave about 500psi in but about how long should a Al80 take to get to 500psi without any moisture issues. Also is there any risk with bleeding a nitrox tank under 40% [like a fire], since it is a hyperoxic mix? Thanks for the help!!
