Hi,
Here is another fact about oxygen.
The most abundant element in the earth's crust is oxygen (49.5%), and air contains about 21% oxygen.
Does that mean that everything around us is 70.5% OXYGEN? Oh and water has two molecules of it too.
I would say the biggest concern is securing the bottles and transport.
Regards
Greg
