I do think you are on to something. Last year the university safety
guys wanted to hang me for doing the CO2 cart demo. I convinced them it
was safe with the proper precautions and that it has been done for years
in 100's of schools without a problem. However, with a safety rating I
very easily could have lost my case.

Perhaps it would be better to think in terms of a set of guidelines
and warnings for the safe use of demos.
I include foot switches, gloves, goggles, etc. with both verbal and
written warnings and instructions for many demos.
A danger ranking would almost guarantee a class of demos being outlawed.
