Possible reasons for this are also cited. CO2 and Helium both increase the risk of O2 toxicity. See again the references cited.

Statistics work as impressive as ever. Two questions Alex;
What specific legal requirement are you referring to in the first statement, curious.
The reference to He & CO2 increasing the possibility of a tox, have you found much tangible evidence to get some conclusions from on this? Any suppositions you might want to share?
Interesting stuff.
