For our veterinary hospital, we have to use only Medical Grade Oxygen. We are not allowed to use welding tanks. We get it from the same distributor as welders, but the Medical grade tanks have to be certified as such.
So I have to ask the question: Is welding grade oxygen really good enough for people to breathe.
As the son of someone who worked in the industrial gas business for 25+ years, the medical grade ox, welder's ox, and ABO are ALL drawn off the same many thousand gallon LOX storage tank. Medical bottles are completely emptied before filling, welder's bottles are topped up.
