About the SSI fatality. Not sure if this is an addition from after the fatality, but today the standards state:
EXAMPLE: Skills like ditching and recovering the scuba unit, breathing directly from the cylinder valve, and any ascents without the regulator in the mouth and/or the breathing gas turned off are not endorsed by SSI, and must NOT be taught during SSI training programs.
Maybe agencies should add to their standards "don't be a dumba$$", but that's probably too vague, so breathing from a cylinder, don/doff, doing emergency ascents with the valve closed, etc..
Stupid things that instructors do without checking with their agency (note previous comment about IQs above 50) will probably result in SSI adding to this list.
