Poll on the use of Nitrox

[LclDiver]

Simple Green is not what you use to O2 clean a tank, that would leave behind film that may leave undesirable odors in your tank. It is not air that causes your tank to become non-O2 clean such as exposing it to ambient air, it is the oil and carbon that can sometimes be expelled from a non-O2 approved compressor. Most shops such as Scuba Center will air fill an O2 clean tank with O2 compatible air for the same price as "regular air".
Also, the idea seems to be here that O2 is flammable. This is a misconception. Oxygen is not flammable in itself, oxygen supports combustion because it is an oxydizer. High concentrations of oxygen make almost everything burn faster and easier than in air.
If you take a nitrox class and the idea or reason behind O2 cleaning is not explained, then your class is not being taught correctly.
