Define GHS!
I just taught a class on this in Amsterdam and another here in the US for my scenic artists. In the course in NYC, I used the GHS format and two MSDSs from Sigma-Aldrich to illustrate the difference between the old and the new data sheets. The Sigma-Aldrich data sheets from 2010 use most of the GHS format. This format has blanks for various toxicity tests required under GHS. You can just look down the blanks and see the either the test results or the words "no data available" which quickly shows when tests have not been done. The only thing Sigma-Aldrich does the old way is that dumb line about not being listed by IARC when instead, they should say that there is "no data available."
I'm so enthused about finally being able to easily demonstrate how few chemicals have been tested, especially for chronic hazards, even when they are in suspect classes. Students and workers need to know that their chemical's hazards are mostly unknown.
