02 Bottles
Is it true that an O2 bottle thats being used must remain above 50 psi. In that as the psi gets below 50 the oxygen can become contaminated/poisonous. Also at low pressures the inside of the bottle is more prone to corrosion.
Does aviation oxygen that stored in a bottle at the correct pressure have a shelf life. Ie if you dont use it all and refil it, do you have to periodically discharge the oxygen and recharge with fresh O2?
