Thanks very much, Maga76. What really stood out to me was her contention that OSHA prohibit requiring the use of masks for long periods without first giving a full medical evaluation! That is useful info and why haven't we heard THAT before? There must be plenty of OSHA people who are aware of that little nugget.
Also that extra O2 is piped into Ors. Very interesting. Thanks again for the summary.
