its not worth it.....swim never saw any p fires,,,,anyone having fires?.....why rid the O2 just to fill the atm will allot of H2..doesnt have to be done...yes h2 is inert but could make a quick flash fire.....swim one time used a small RB and directly after the rxn didnt let the h2 do itsthing (sit for 20mins) and just directly poured the contents of the RB into another vessel and a flash fire (small one) occured...the rb was flung about 2 feet and a popping sound was heard with a firecracker looking sounding blast (small fire-cracker--salute)
swim would technique and safety are much more important than ineret gas...and save the inert for a reductive amination
your creating an inert gas and any put in would be driven out with the push
