Aside from other issues, like they weren't enforcing them anyway, and even then they were only a snapshot view of compressor operations with samples probably taken at times of highest quality expectations - immediately after filter changes, early mornings when the machines were coolest, etc. Of the compressors that still send samples tho, 3 to 5% of those are failing still...
See CO Poisoning Risk Higher Than You Think: Undercurrent 07/2012
I remember well the mentioned SB Accident thread. It got pretty heated between some of us, as some only wanted to mourn the loss of the CCV DM while some of us were as upset over the loss of the Texas tourist R.Gibbs and excited that this could happen. The resort promised full disclosure on their own forums board, but then both threads vanished, and there has been little information available about the accident since. At least this all lead to the development of the Passings forum here on SB, and changes in the special rules for Accidents which prohibit condolences on that forum less they distract from objective discussions - even if that clause is often not enforced if it does not seem to cause problems.
I was flattered that Undercurrent asked permission to use my article Carbon Monoxide in Scuba Tanks: Risks and Protection but I think my style may have been a little forward for them, and - the chosen article published is certainly a fine one. I really liked their closing paragraph...

I suspect that if a city told its residents it was no longer testing for E. coli in the drinking water, most people would stop drinking that water or want a testing device for E. coli to use at home. With the largest dive training agency on the planet no longer requiring its affiliates to test their breathing air quality on a quarterly basis, the time has come for individual divers to routinely carry a CO analyzer so that they can test for this odorless, tasteless and toxic contaminant in their tanks and prevent themselves from becoming a possible fatality.
