Use Argon.

Several have suggested purging the tanks with Nitrogen. Please remember
that Nitrogen does displace Oxygen and that we need the Oxygen to live.
We (at GE Plastics) lost a couple of folks who entered a 'pure' Nitrogen
purged vessel not remembering no Oxygen was available. Death came after
only a few breaths.... can't see it or smell it. Be careful! Earl
